Re- Proposal to Provide Engineering Design Services for- the Testing, Evaluation
and Recommendations Relating to Colored Water
Dear Mr. Bauman:
The purpose of this letter is to transmit our proposal prepared in response to your RFP,
dated August 1'), 2007, requesting proposals to provide Engineering Design Services for
the Testing, Evaluation, and Recommendations Relating to Colored Water, Trussell
Technologies, Inc. is particularly pleased to submit a proposal in response to this RFP
because we believe this is a project that our organization is uniquely suited to perform.
Also, we want to personally thank you for the time you spent explaining the situation to
us and helping us understand San Juan Capistrano's needs. We have retained the services
of the Akel Engineering Group to assist us on the system modeling in Task 4. Tony
Akel's experience in this area is exceptional, and we are confident you will be pleased.
Colored water problems have plagued water utilities from the beginning of time. We feel
it is important to resolve these problems because they have a direct impact on consumer
confidence. At the same time, such problems are often not easily solved. The key to
success in resolving such problems is to determine their cause. As a result we support the
basic approach outlined in the RFP and, as you requested, we have prepared a scope of
work and an estimate designed to respond directly to the services described in the RFP.
At the same time we are proposing some changes to the approach detailed in the RFP in
the form of an optional scope. We believe these changes will save the City money and, at
the same time, improve the chance of success. They are based on our experience that
such color problems often result from gradual accumulation of iron and/or manganese in
the system over time, and show a poor correlation with the performance of the treatment
plant on any one given day. As a result we are proposing a unique application of
composite samplers; both at the treatment plant and in the distribution system to
simultaneously accomplish three objectives: a) find if there is a direct correlation between
treatment plant effluent quality, b) document conditions in the distribution system
throughout the year, and c) document the quality of all the streams in the treatment plant
so that efforts to troubleshoot the treatment process can be targeted where the), will make
the most difference. In this regard, we propose sampling raw water header, the bypass
strearn, the recycle stream, the RO strearn and the final product water from the clearwell
so that all aspects of plant performance can be examined.

RE: Proposal to Provide Engineering Design Set -vices for the Testing, Evaluation
and Recommendations Relating to Colored Water
We propose that, during normal weeks, a single week-long composite sample be prepared
for sites throughout the treatment plant and in the distribution system. This will give us a
complete record of all the inputs and outputs. So that this composite can be prepared, we
plan to save the composites from the first part of the week so they can be combined into
one composite at the end of the week. These stored samples create another opportunity.
When a colored water incident occurs, we will be able to analyze water throughout the
system and the treatment plant for several days before and after the incident. This
maximizes the likelihood that we will be able to identify any correlations to be found.
We save money but learn more.
It is also proposed that the budget for pilot studies be retained by the City until a time
when testing can be identified that will directly address the cause of the color problem.
Based on the information we've seen to date, there are three possible issues that might be
investigated at the treatment plant: a) poor performance of' oxidants ahead of the
greensand filter (target of the pilot work proposed in the RFP), b) interference of recycled
wash water with the performance of' the greensand filters (this was the problem in the
Camp Pendleton system where Trussell Tech is involved in a project to improve
performance), and c) poor performance of the RO in removing manganese (manganese is
now higher than anticipated during design). Desktop studies may show that pilot testing
is not required.
Trussell Tech has reviewed the sample Professional Services Agreement provided by the
City and is claiming no exception to its standard terms and conditions. This proposal is
an offer valid for a 90 -day period.
We hope you find our proposal interesting and responsive. We assure you that if Trussell
Technologies, Inc. is selected to do this project you will receive the direct attention of the
principals of the firm.
Very Truly Yours

PROPOSAL To PROVIDE ENGINEERING DESIGN SERVICES FOR THE TESTING, EVALUATION, AND
RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
PROJECT UNDERSTANDING
The City of San Juan Capistrano (henceforth
referred to as the "City") has been receiving
persistent colored water complaints in its
distribution system. The City hired Malcolm
Pirnie Inc. (JMPI) to develop a Study Plan to
assess water quality issues associated with the
complaints. The proposed project
encompasses execution of the Study Plan as
written by MPI. At the same time, the
proposed project will lay out an alternative
strategy to identify the source of the color and
to eliminate the colored water episodes. It is
our belief that judicious use of week-long
composite samples at several locations will
improve the chance of success. We also
propose that the City retain the budget for
pilot studies until a time when it is certain that
the testing to be conducted will directly
address the cause of the color problem.
BACKGROUND
Before providing background on the specific
problem being experienced by the City, it is
useful to provide a little background on the
experiences of other utilities with colored
water problems.
Colored Water Colored water is a common
cause of consumer cornplaints and there are
many causes of colored water. The most
common example is the colored water that
occurs in the dead ends of almost every water,
system. For most of the 20"' century cities
with low alkalinity water (e.g. Portland, OR;
Tacoma and Seattle, WA; Boston, MA; New
York, NY; and Sydney, Aus.) experienced red
water complaints resulting from iron release in
cast iron mains. These same cities also
experienced blue and green water at the
consumer's taps due the action of the same
water on consumer plumbing. A few cities
have also experienced a blue water
phenomenon that has been attributed to the
action of bacteria On Consumer plumbing (e.g,
EBMUD in Oakland, CA). Another common
problem is the red water after a municipality
changes from an unchlorinated deep well
supply to a chlorinated surface supply. This
happened in parts of Long Beach in the 1960s,
in Upland, CA in the 1970s and in Tucson, AZ
in the 1990s. Red watei is also more common
in systems with high chloride water using cast
iron or ductile iron mains. Besides dead ends,
the most prevalent colored water problem
today is probably red water associated with
iron mains.
Yellow, brown or black water associated with
manganese is also a common problem. Some
confusion exists concerning acceptable levels
of manganese. EPA's secondary MCL for
manganese is 50 ltg/L. Although keeping
mangaDese below 50 lig/L is usually adequate
to prevent staining of fixtures, lower levels are
required to prevent periodic occurrences of'
colored water. Over the years, the quality of
the distribution systems has improved,
consumers have become accustomed to higher
quality water and more utilities are now
finding that very low manganese levels are
required to prevent consumer complaints.
When manganese is present in water entering
the distribution system, it deposits on pipeline
surfaces and, periodically the deposit comes
loose, making colored water. In 1960, A.
Griffen, Chair of the AWWA Task Group on
Manganese Deposition in Pipelines concluded
that a range of 10 to 20 pg/I could be safely
tolerated (Griffen, 1960). Thirty years later a
careful study was done in Brisbane, Australia
(Sly et al, 1990). This study reported that
consurner complaints were only eliminated
when manganese levels in the treatment plant
effluent were consistently less than 20 lig/L,
with an average level near 10 gg/L

PROPOSAL TO PROVIDE ENGINEERING DESIGN SERVICES FOR THE TESTING, EVALUATION, AND
RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
San Juan Capistrano. The City has historically
relied on imported water from the
Metropolitan Water District of Southern
California (MWDSC) as the primary source of
its drinking water. In order to decrease its
dependence on imported water, the City
retained ECO Resources Inc. to design, build,
and operate a Ground Water Recovery Plant
(GWP,P) to treat groundwater from six wells:
Capistrano Valley Water District (CVWD- 1),
Dance Hall. Kinoshita, San Juan Basin 2
(SJB-2), San Juan Basin 4 (S.113-4). and
Tirador.
Well water quality The six wells serving the
GWRP have varying quality. Table I -I shows
the average turbidity, iron, manganese, and
TDS for each of the six wells based on
sampling conducted in 2004 along with the
design raw water quality (DRWQ). Iron and
manganese are highlighted because they often
cause color episodes in distribution systems.
Table 1-1 also shows the maxiinuin
production that was anticipated from each
well. Table I -I shows that certain wells are of
considerably lower quality than others,
notably Dance Hall and Tirador. The report
by Boyle cited in Table 1-1 also noted one
well would be used as a stand-by well and that
not all wells would be used under typical
operation. The Boyle report also showed a
scenario where blending Five wells would
result in a manganese concentration that
exceeded the DRWQ (Boyle 2004).
Based on the experience of ECO Resources in
operating the plant, it is known that the wells
were not capable of producing the anticipated
amount of water shown in Table 1-1 (Drehet,
2006). Therefore, it is possible that the
blending of well water may result it,
conditions where the DRWQ for manganese is
exceeded. It has been observed recently that
the blended well water nianganese
concentration has been hi(,her than the
DRWQ, — 1.5 mg/L (Bauman, 2007). While
the blended well water manganese
concentrations have been higaher than
expected, they are consistent over a period of
time and not subject to fluctuations that
correspond with the color episodes.
Therefore, the City believes the well water
quality, alone, is not likely the cause of the
intermittent color episodes (Bauman, 2007).
Description of the Groundwater Recovery
Plant (GWRP). The GWRP treats a portion of
the flow with reverse osmosis preceded by
conventional multimedia filtration
pretreatment. No oxidants are added upstream
of the RO process. The remaining portion of
the now bypasses the RO and is treated by
oxidation followed by greensand filtration.
For the bypass stream, sodium hypochlorite is
added prior to the greensand filter to oxidize
the iron and potassium permanganate is added
to oxidize the manganese. Figure 1-1 shows a
simplified schematic of the GWRP process.
Figure 1-1 includes enough detail to describe
the issues related to the proposed project and
is not intended to show all details. For
example, certain chemical feeds are omitted
from Figure 1-1, such as the sodium bisulfite
added upstream of the RID, the caustic soda
added to the RO permeate, the free chlorine

Colored water complaints. The City has
received persistent colored water complaints
from residents since the GWRP began
operation in December- 2004. A map of the
distribution system provided by the City
showed that in eight colored water episodes
since 2005, most of the customer complaints
occurred in the 250S pressure zone.
July 2005. A colored water complaint was
received in July 2005 that resulted in
operational changes to the GWR -P. On July
17: 2005, the GWRP had a turbidity spike of >
1.0 NTU that lasted for 12 minutes, During
the episode, customers were calling the City
complaining of "brown water." At the time,
the GWRP was not alarmed for turbidity
spikes (Dreher, 2005a).
Upon investigation, it was deten-nined that
solids buildup in the washwater recovery
tanks was resulting in increased turbidity of
the clarified washwater recycle line that is fed
to the RO bypass greensand filters. In
essence, it was determined that the washwaiei
line was drawing from a layer of high
concentration solid material at the bottom of
the washwater recovery tanks. In the short-
term, ECO began pumping out the higher -
concentration material from the %vashwater
recovery tanks, For the long-term, ECO
instituted weekly flushing of backwash water
to the SOCWA wastewater plant and initiated
a program of visual inspection of the
backwash water tanks interior, to determine if
buildup is occurring. Additionally, an alarm
was put in place to shut down the washwalet
recovery purrips when turbidity in the RO
bypass filter effluent exceeds 0.2 NTU
(Dreher, 2005a).
September 2005. A colored water
complaint was received in September 2005
that resulted in additional changes to the
GWRP Operating procedures. On September
23, 2005, a turbidity spike was observed in the
GWRP in the influent to the clearwell (see
Figure I -I) with a duration of 1. 5 hours and >
I NTU for 20 minutes (Dreher, 2006b).
In a letter from ECO's plant operator to
CDHS, it was noted that it was only the
second time since plant operations began that
colored water complaints were preceded by a
turbidity spike. It was also noted that "post
pi ior incidents have been related to
distribution system issues." (Dreher, 2006b).

Additional modifications to plant operations
were made aftei this incident. The online
turbidirneter on the RO bypass stream had
been "active" only when the plant was in the
backwash recovery, process. After the
incident, the RO bypass filter effluent
turbidity alarm was set to remain active 24/7
and the plant's distribution pumps were set to
be shutdown by this alarm. After the July
2005 incident, a procedure was put in place to
waste the Fc/Mn solids sludge from the
bottom of the washwater recovery tanks
weekly. After the September 2005 colored
water episode, the frequency of this process
was increased to three times per week (MWF)
(Dreher, 2006b).
Evaluation of July and September 2005
Colored Water Episodes by MPI. The City
retained MPI to identify corrective measures
for water quality issues causing- "customei
complaints of red and brown water resulting
from excessive levels of iron and manganese
concentrations in the distribution system
samples." MPI was also asked to evaluate
potential areas of concern regarding the
GIAIRP's ability to produce 4800 AFY (MPI,
2006).
The MPI evaluation corroborated the
observations made by F -CO's plant operator
(Dreher, 2006a&b) that high turbidities in the
washwater recovery line contributed to the
elevated turbidities in the July 2005 and
September 2005 incidents of colored water. It
was reported that the online turbidity
analyzers for the RO bypass and blended RO
permeate/R0 bypass water samples had limits
of 10.0 and 1.0 NTU, respectively. In the July
and Septenibei 2005 incidents, these limits
were reached and actual turbidity values may
be higher than those reported for these
streams. MPI also reported that it is "highly
unlikely that RO membrane operation resulted
in the excessive turbidities obseived hi the
City's distribution system (MPI, 2006).
For the RO bypass treatment train, MPI
recommended installation of an online
turbidimeter on the washwater recycle line to
the RO bypass filter to continuously measure
turbidity and made several recommendations
involving GWRP operations. They also noted
that changes to plant operations that increase
"the particulate and solids loading to the
filters, such as oxidizing and filterin.- the
complete plant now or operating the
Backwash Recovery tanks in a less than
optimal manner for solid separation may
require construction of additional Filters or
washwater recovery tanks (MPI, 2006),
In their evaluation, MPI also recommended
that ECO consider modifications for RO
pretreatment to remove iron and noted that
ECO is considering adding a sodium
hypochlorite feed to the entire plant now
(sand separator innuent) to oxidize it -on and
remove it in the RO feed filters prior to the
RO and avoid probleiris with membrane
fouling. MPI also recommends that if this
strategy is followed, there are several concerns
that must be addressed (MPI, 2006):
• The RO feed filters may not be
adequately sized to handle the
increased loading and additional filters
may be needed
• The RO feed filters will need to be
backwashed more frequently, resulting
in more wastewater to the washwater
recovery tanks and possibly a need For
additional tankage
• The sodium hypochlorite may come in
contact with the RO inernbranes and
daniage them so careful evaluation of
the sodium bisulfite feed system to
avoid this potential problem is needed.
• Manganese is not likely to be fully
oxidized by the sodium hypochlorite,

but it may be partially oxidized and
could foul the RO membranes.
Based on the raw data in Attachment A of
MPI (2006)., Trussell Tech constructed a
probability plot of average RO Feed
conventional filter effluent compared to
average RO Bypass greensand filter effluent
for the period June through September 2005.
As shown on Figure 1-2, the RO bypass
greensand filter produces a lower effluent
turbidity than the RO feed conventional filters.
This suggests that a strategy to oxidize iron in
the complete plant flow and increase the
loading of the RO feed filters may indeed
require the installation of additional RO Feed
filters.
EVALUATION OF THE COLORED WATER
PROBLEM AND POSSIBLE APPROACHES
TO SOLUTION
The Tasks as laid out in Exhibit A by MPI
will probably resolve the colored water
problem, but Trussell Tech believes that, if
some modifications are made to this approach,
the chances of success can be improved and
the cost of the project can be reduced.
('oncepts Behind the Optional Approach. The
following four tasks were laid out in Exhibit
A:
1. Task I -- Sampling
2. Task 2 — Evaluation of' Treatment
Alternatives
1. — Optimization of GWRP
_3 Task 3
Processes
4. Task 4 — Optimization of Distribution
System Operations
Trussell Tech. would like to suggest
modifications to Tasks I and 2. As it is
currently specified Task I would collect daily

EVALUATION OF THE COLORED WATER
PROBLEM AND POSSIBLE APPROACHES
TO SOLUTION
The Tasks as laid out in Exhibit A by MPI
will probably resolve the colored water
problem, but Trussell Tech believes that, if
some modifications are made to this approach,
the chances of success can be improved and
the cost of the project can be reduced.
('oncepts Behind the Optional Approach. The
following four tasks were laid out in Exhibit
A:
1. Task I -- Sampling
2. Task 2 — Evaluation of' Treatment
Alternatives
1. — Optimization of GWRP
_3 Task 3

4. Task 4 — Optimization of Distribution
System Operations
Trussell Tech. would like to suggest
modifications to Tasks I and 2. As it is
currently specified Task I would collect daily
samples at three points in the distribution and
at the following locations at the treatment
plant: a) the blended well water, b) the bypass
water, c) the recycle water, and d) the product
water,
Optional Approach to Sampling The
optional approach would collect coniposite

RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
Five sample bottles will be purchased for each
of the composite samplers, one for each day of
the work week. Each day, the oldest
composite sample will be thrown away at each
site and the bottle reused. As a result, there
will always be four earlier samples as well as
the sample for the current day at each sample
site. At the end of each week, an aliquot will
be taken from the composite sample for each
day and poured into one sample bottle for
each site, provided by the laboratory - to
create one overall composite sample for each
sample site Im the week. This approach
provides a complete characterization of plant
performance and of conditions in the
distribution system, but it reduces the sample
load by 80 percent.
When an incident occurs and color complaints
are triade, the four previous samples will be
analyzed as well as sample for the day of the
incident as well as the samples for the
following two days. As a result we will have
sound data on the overall long-term conditions
at all sample sites as well as a specific daily
record before and after each incident. Equally
important samples before and after the
incident can be preserved for future analysis
should questions arise.
Optional Approach to Pilot Work
Trussell Tech also recommends that a decision
to conduct the pilot work proposed in Task 2
be postponed until the completion of the
oxidants analysis in Task 2, the optimization
analysis in Task 3 as well as the first 4-6
months of the sampling program as well as
preliminary work on Task 4. This will put the
team in a strong position to judge the cause of
the colored water problem, to understand the
part of the plant that is not meeting the city's
needs and if piloting is necessary to address
the problem.
Trussell Tech believes the decision to pilot
preoxidants is prerriatine at this time for the
following reasons:
I ) Piloting is expensive and should out), be
conducted if there are identifiable
berefits.
2) The Clilorine-pei-iiiaiiganate-a,i-eeiisand
approach used on the bypass stream at
the GWRP is accepted as the state of the
art for the removal of iron and
manganese and it is successfully used
throughout the country.
3) There is a reasonable possibility that
other problerns at the GWRP are
responsible for the color problem and it
is not clear that an oxidants pilot study
would resolve these. Examples are a)
the possibility that the washwater
recycle, while improved, is still
interfering with performance and b) the
possibility that the RO membranes it) the
GWRP, which have been cleaned man),
times an which ate constructed with no
brine seal, are contributing to the
problem.
4) The use of an oxidant on whole flow
may void RO membrane warranty.
Boyle proposed gieensand treatment for
the whole now during the original
desi,,ri but was forced to change to
conventional filters before RO and avoid
oxidants in order to gain the cooperation
of the RO manufacturer.
5) There is very limited or no turbidity data
for the RO permeate and the washwater
recovery streams and very limited iron
and manganese data for any streams
other than the raw water and product
water. This data is essential for the
analysis of possible treatment solutions.
6) Until the sampling, source tracking- and
t1ushing studies are completed it is not
certain that improving oxidation at the
GWRP is the most cost-effective means
of solving the color problems.

Approach to Hydraulic Modeling. A hydraulic
model, developed based on information
extracted from the City's existing GIS shape
Files for the 250 pressure zone, will be the
central tool for the source tracing task,
Hydraulic pathways from and to the 250
pressure zone will be considered to establish
the boundary conditions and bypass modeling
the entire City-wide system at this time.
Sources of watet at the locations of elevated
iron and manganese occurrence within the
distribution system will be determined. The
intent of this task is to determine if the
complaints are resulting from the operation of
the treatment facility or due to operation of
certain distribution systern infrastructure.

The project approach and scope of services
will build upon the logic laid out in the Project
Understanding (Section 1). The scope will
encompass execution of all the Tasks as laid
out in Exhibit A of the REP. In additiOD, all
optional approach to Task I and Task 2 will
be included that Trussell Tech believes will
3esu It in a determination of the cause of and
the solution to the colored water episodes at a
cheaper cost to the approach defined in the
RFP.
TASK 1 — SAMPLING OF THE RAW
WATER, GWRP TREATED WATER AND
AT THE DISTRIBUTION SYSTEM
The purpose ofTask I is to collect regular
monitoring data frorri the raw water, from
various locations in the GWR -P, and from the
distribution system to aid in determining the
source, cause, and extent of the colored watei
problems. Table 2-1 shows the deliverables
for Task I broken down by sub -tasks. The
scope of services for Task I will be described
below for both the approach described in
Exhibit I of the RFP and the optional
approach recommended by Trussell Tech.
Approach in the RFP The scope of services
for the approach laid out in the REP is
described below. As shown in Table 2- 1, a
sampling plan and database for storing sample
data will be developed before sampling
begins. In addition, operators will be briefed
on the sampling plan so they will be prepared
to take the samples. A local lab was contacted
in preparation of the project budget so the
seeds of developing a sample collection and
preservation protocol have been planted.
Task I A Influent Water. As shown in
Table 2-1, grab samples for the influent water
for the constituents shown in Table 2-1 will be
collected daily (5d/wk) at varying times
throughout the day over a 12 -mo. period. As
an alternate approach, composite samples will
be collected daily (5d/wk) over a 12 -mo.
period.

Task I B GWRP I reated Water Sampling.
As shown in Table 2 -1 . the GWRP treated
water will be sampled for the constituents
shown in Table 2-1. Samples will be collected
daily (5d/wlo at varying times throughout the
day over a I 2 -mo. period. As an alternate
approach, composite samples will be collected
daily (5d/wk) over a 12 -mo. period.
rask I C Additional Sampling when
Turbidity Spikes or Colored Water is
Reported. An intersive plan for sampling the
Plant when turbidity spikes > 0.3 ntu or when
colored water is reported will be developed.
Based on past online turbiderrieter data and on
the historical record of color complaints, 20
such events were included in the project
budget. The constituents to be sampled and
the sample locations in the GWRP are shown
in Table 2-1, The preliminary plan, to be
revisited before the sampling begins, is to
have the operators sample at each sample
location in the Plant four times per day for the
day a color event is reported and also the
following day for a total of eight samples.
Task ID Distribution System Sampling
when Turbidity Spikes or Colored Water is
Reported. Air intensive plan for sampling the
distribution system when turbidity spikes >
0.3 ntu or when colored water is reported will
be developed. Based on past online
turbidemeter data and on the historical record
of color complaints, 20 such events were
included in the project budget. The
constituents to be sampled and the protocol for
sample locations in the distribution system, to
be determined before sampling begins, are
shown in Table 2-1. The preliminary plan, to
be revisited before the sampling begins, is to
have the operators sample at each sairiple
location in the distribution system two times
per day for the day a color event is reported
and also the following day for a total of eight
samples.
As an alternate approach, a composite samp lei,
will be placed in the distribution system at a
location to be determined before sampling
begins. The composite samples will be
analyzed for the constituents shown in Table
2- 1. The preliminary plan, to be revisited
before sampling begins, calls for samples to
be collected under the same procedure as for
the distribution system grab sampling (2X/d
for the day of and day following an event).
Optional Approach Recommended by Trussell
Tech. As discussed in the Project
Understanding (Section 1), Trussell Tech
recommends an optional approach to meet the
objectives of the Task I Sampling at a cheaper
cost to the sampling prescribed by the RFP.
The optional approach would collect
composite samples at the same locations daily.
More intensive surveys would be conducted if
a color incident in the distribution system.
Trussell Tech suggests that composite
samplers be installed throughout the GWRP
and in the distribution system (locations to be
described in the sub -sections below).
Sampling Protocol for the Optional
Approach Recommended by Trussell Tech.
The protocol for sampling is as follows. Five
sample bottles will be purchased for each of
the composite samplers, one for each day of
the work week. Each day, the oldest
composite sample will be thrown away at each
site and the bottle reused. As a result, there
will always be four earlier samples as well as
the sample for the current day at each sample
site. At the end of each week, an aliquot will
be taken from the composite sample for each
day and poured into one sarnple bottle for
each site, provided by the laboratory - to
create one overall composite sample for each
sample site for the week. This approach

provides a complete characterization of plant
performance and of conditions in the
distribution system, but it reduces the sample
load by 80 percent.
When an incident occurs and colored water is
reported, the four previous samples will be
analyzed as well as sample for the day of the
incident as well as the samples for the
following two days. As a result we will have
sound data on the overall long-term conditions
at all sample sites as well as a specific daily
record before and after each incident. Equally
important samples before and after the
incident can be preserved for future analysis
should questions arise. Based on the historical
record, the fee proposal is based on six
colored water incidents being reported during
the one-year sampling program time frame,
Task [A Influent Water A composite
sampler will be installed on the influent water
stream and samples collected and analyzed as
described above. Sampler location:
I . The blended well wato (point "I" on Section
1, Fig-, I - 1)
Task I B/ I C GWRP Water Sampling
Composite samplers will be installed on the
following locations in the GWRP:
2. Theblended wellwater(point "I" on Fig. 1-1)
3. The washwater recycle line
(point "5" on Fig. I - 1)
4. The Bypass line (point "T' on Fig. 1-1)
5. The RO effluent (point "Y' on Fig. 1-1)
6. The product water exiting the clearwell
(point "4" on Fig. I - 1).
Samples will be collected according to the
protocol described above, which includes the
plan for regular sampling and analysis of the
GWRP along with the sampling and additional
analysis perfornried during events when
colored water is reported.
Task I D Distribution System Sampling
when Turbidity Spikes oi Colored Water 'is
Reported Composite samplers will be
installed at the following locations.
7, Three locations in (lie distribution system, to
be determined during preliminary planning.
Samples will be collected and analyzed
according to the protocol described above,
TASK 2 - EVALUATION OF TRFATMENI
At TERNATIVES
As stated in Exhibit I of the RFP, "this task
will evaluate alternatives for treatment of
colored water. Assuming that colored water is
caused by the presence of iron and manganese
in the water, oxidation followed by filtration is
the most preferable solution. Treatment
alternatives will be evaluated in this task
assuming that GWRP operations will not be
altered in response to an iron or manganese
spike in the raw water." An optional approach
to this task is recommended by Trussell Tech
in which the pilot study (Task 2.A.b) will not
be conducted at this stage of the project for
reasons discussed in the Project
Understanding (Section 1).
Approach in the RFP. rhe defiverables for
Task 2 are summarized in Table 2-2.

Each sub -task will be described below.
Task 2A Pre-treatment Alternatives
Evaluation This task will consider addition
of an oxidant chemical to the blended well
water to oxidize iron and/or manganese for
subsequent removal in the GWRP by the RO
bypass Filters oi the RO feedwater filters.
Task 2A.a Desktop Study As shown
in Table 2-2, this sub -task will analyze several
alternative pre -oxidants for the oxidation of
iron and manganese including free chlorine
and chlorine dioxide. The results will be
Summarized in a letter report selecting one
pre -oxidant for further consideration in the
project.
Task 2A.b Pilot Study The selected
pre -oxidant FTom Task 2.A.a will be tested in a
pilot study to demonstrate its applicability for
iron and manganese removal. The pilot study
will be performed for a period of 3 months
and is to be conducted on a side -stream of
blended well water prior to its entry to the
GWRP. After addition of pre -oxidant to
remove iron and manganese, the blended well
watei will be treated bys temporary
greensand filter in the pilot study to remove
precipitated iron and manganese. The fee
proposal includes rental of a greensand filter,
time for a Trussell Tech engineer to setup the
pilot study and assist the operators in running
the pilot experiment, and budget for laboratory
analysis of iron and manganese (total and
dissolved) in the feed and downstream of the
greensand Filter. The pilot study will run 24/7
as intermittent operation will introduce
reactions that will not be present during Full-
scale operation and potentially compromise
the results. The detiverabtes for Task 2.A.b
are summarized in Table 2-2.
Task 2A.c Conceptual Design and
Layout, VarousTrussell Tech engineers have
extensive experience with conceptual design
and layout. In this sub -task a conceptual
design and layout for the selected alternative
oxidant will be performed.
Task 2B Post-treatmern Alternatives
Evaluation Another alternative approach to
reduce iron and manganese levels entering the
distribution system is to post -treat the GWRP
treated water with an oxidant feed followed
by filtration. As shown in Table 2-2, the
deliverable wilt be a desktop soidy of post-
treatment alternatives.
Task 2C Conceptual Level Cost
Estimation. As shown in Table 2-2, the
deliverable is I Level 4 (-30%, +50%) cost
estimate for the selected pre-treatruent (from
Task 2A) and post-treatment (from Task 213)
alternatives. The Trussell Tech engineers
participating in this project have broad
experience with Level 4 cost estimates.
Optional Approach Recommended by Frussell
Tech. Trussell Tech recommends that a
decision to conduct the pilot work proposed in
Task 2 (Task 2A.b) be postponed until the
completion of the oxidants analysis in Task 2,
the optimization analysis in Task 3 as well as
the first 4-6 months of the sampling program
as well as preliminary worl, on Task 4. This
will put the team in a strong position to judge
the cause of the colored water problem, to
understand the part of the plant that is not
meeting the city's needs and if piloting is
necessary to address the problem. Trussell
Tech believes the decision to pilot preoxidants
is premature at this time for the reasons stated
in the Project Understanding (Section 1). As a
part of the optional approach recommended by
Trussell Tech discussed in Task 1, the fee
proposal includes this strategy of not
conducting the pilot study as a part of this
project as an element of the optional approach.

TASK 3 - OPTIMIZATION OF GWRP
PROCESSES
The purpose of Task 3 is to optimize the
performance of the GWRP for better removal
of iron and mangoarrese. According to Exhibit
I of the RFP, "the premise of this task is that a
well operated systern such as the one at
GWRP should be capable of effectively
removing iron and manganese from the well
water, which is anticipated to be the source of
colored water complaints." The deliverables
for Task 3 are summarized in Table 2-3.
TASK 4 - OPTIMIZATION OF
DISTRIBUTION SYSTEM OPERATIONS
Table 2-4 presents a list of deliverables for
Task 4. Each sub -task will be described in
detail below.
Task 4A Evaluation of the 250 Zone
Operational and Functional Conditions The
purpose of Task 4A is to assess water quality
conditions in the 250 pressure zone because
most of the colored water problems have been
associated with the 250 pressure zone, There
is a concern iron valves and other fixtures in
the distribution system may be subject to
corrosion and contributing to the colored
water episodes. The 250 pressure zone also
includes the older part of the City and there
may be unlined iron pipe in the distribution
system though the City has stated that the
colored water reported by consumers is not
typically associated with the older parts of the
250 pressure zone (Bauman, 2007). Water
samples will be collected at the frequency, in
the locations, and for the constituents
described in Table 2-2 in order to assess the
potential for corrosion contributing to the
colored water episodes. Trussell Tech
engineers have a unique expertise in this
particular area.

'I ask 4B Source 'I racing. Task 4B will be
divided into six sub -tasks discussed below.
Task 4B I Meetings. Data Collection, and
I ask Management This task includes project
triectings, data collection, task management,
meeting -agendas, and monthly progvess
reports.
Task 4132 Seasonal Demand Analysis and
Geocoefing from Water Billing Records.
Monthly City-wide production records for the
past 5 years will be evaluated to determine the
seasonal demand variations within the City.
The objective is to identify the maximum day
demands, typical average day demands, and
the low winter demand periods. Water age
tends to be a factor during the to", demand
periods. In this task, water demand peaking
factors will be recommended.
The hitting records will be normalized and
geocoded to the model junction nodes within
the 250 Pressure 70nes This methodology
provides a more accurate distribution of
demands for modeling purposes. Though this
task will focus on the pressure zone 250, this
same methodology can be used by the City to
complete the assembly of the entire
distribution system, following the completion
of this project.
Task 4B3 Hydraulic Model Development
from GIS and from Input/Output Location
Information. The City has invested in a GIS
that includes the water distribution system and
its appurtenances. The 250 pressure zone
includes approximately 15,000 pipes, 5,300
valves, and 1,700 hydrants.
The GIS shapefiles will be exported to the
hydraulic model. The project team is equally
competent with commercially available
hydraulic models including MWHSoft
H20NET, H20MAP Water, and Infowater, as
well as Bentley's WaterGEMS.
It is our understanding that City staff currently
own an 1420MAP water license. Since the
hydraulic engine contained in these software
packages are identical, our team Proposes to
perforin the analysis using a software most
preferred by City staff. A long term City goal
may be to build on the 250 pressure zone
model and assemble a City-wide model that
will be maintained by City staff During the
kickoff meetina we will discuss the benefits of
7
using 1120MAP Water, currently owned by
the City, versus Infowater which runs inside
ArcMAP,
Since the 250 pressure zones is interconnected
to other pressure zones, the boundary
conditions consisting ofwater flowing into
and out of this zone, are exceptionally
important. Historical and seasonal operational
data for water entering and leaving this zone
will be collected from the SCADA system.
The intent is to simulate realistic boundary
conditions for the demand scenarios that will
be used for the source tracing task.
Task 4134 Hydraulic Model Calibration to
SCADA and optional Pressure Monitors,
Calibration provides a measure of confidence
in the model simulated results. SCADA data
will be used to calibrate the boundary
conditions, including the operations of pump
stations and storage reservoirs influencing this
pressure zone. Calibration within the
distribution system of the 250 pressure zone is
an optional, though desired task. This task
involves installing up to 6 pressure loggers at
critical locations within the distribution
system and monitoring pressures for a period
of one week. This task assumes the pressure
loggers, if available, will be installed by the
City's operation staff.
The model will be calibrated for the extended
period simulation, using the data available
from SCADA and the optional pressure
loggers.

'I ask 4135 Source Tracing In this task, the
model will be used for the source tracing
simulations. Water age through the
distribution system will be mapped for
average day demand, maximum day demand,
and minimum winter day demand. The
model will be used to monitor the area of
influence from each source entering the 250
pressure zone and from the storage reservoirs.
The focus of the analysis will be the areas of
elevated iron or manganese occurrences
within the distribution system,
The preliminary analysis results will be
presented to City staff for discussions and for
evaluating further analysis scenarios. The
team feedback will be used to model the final

AGENDA REPORT G 2a
TO: Dave Adams, City Manager &A
FROM: Cindy Russell, Interim Public Works Director
SUBJECT: Consideration of Agreement for Colored Water Study and Appropriation of
Funds (Trussell Technologies Inc.)
RECOMMENDATION:
By motion,
1. Approve the agreement with Trussell Technologies Inc. to test and evaluate for
the causes of the colored water in the distribution system in the amount of
$199,939;
2. Appropriate $250,000 from the Ground Water Recovery Plant (GWRP) fund
reserves to cover the cost of the Colored Water Study.
SITUATION:
The City of San Juan Capistrano has experienced a significant level of customer
complaints about colored water since June of 2005. The problem was at first mitigated
through a program of hydrant flushing when complaints occurred. At this point, the
frequency and degree of complaints have risen beyond levels that can be addressed by
a flushing program. Given that colored water can come from many complex interactions
or even multiple sources, the City hired Malcolm Pirnie, Inc. to develop a Study Plan to
assess water quality issues associated with the colored water. This Study Plan was
utilized as a means of defining the problem and the approximate range of investigation
needed in a solicitation of proposals to perform the study of the colored water problem.
The Study Plan was prepared after careful evaluation of the data available to Malcolm
Pirnie related to the colored water occurrences. The available data included; a) The
Ground Water Recovery Plant (GWRP) system and basic operational information, b)
information about the distribution system network, c) raw well water quality, d) water
quality being produced by the GWRP, and e) listing of the customer complaints during
colored water occurrences. The proposed Study Plan included several tasks designed
to carefully evaluate the potential sources and causes of the colored water. The tasks
consisted of sampling of the water in the system including: import, well, system water at
several points, raw water and the product water of the GWRP. The sampled water is to
be tested for key parameters that could explain the source of the color and the exact
Agenda Report
Page 2 October 2, 2007
mechanism by which it materializes. After a careful evaluation of the source(s) of the
problem, the Study Plan considered an evaluation of the solutions including: a desk top
study of corrective actions, a pilot treatment plant, and a cost evaluation of the studied
solution.
The Study Plan was solicited to firms that have experience in the study and evaluation
of colored water. The firms were PSOMAS & Assoc., Black & Veatch, Malcolm Pirnie,
and Trussell Technology, Inc., Proposals were received from Malcolm Pirnie and
Trussell Technology. The proposal by Malcolm Pirnie follows the Study Plan with no
changes. The proposal by Trussell Technology followed the Study Plan except for a
recommendation to remove the pilot study, and Trussell included the cost of testing in
its response, unlike that of Malcolm Pirnie. Trussell's recommendation to drop the pilot
study was based on its evaluation that the true nature of the problem had not yet been
identified, and that the results of the monitoring and sampling combined with the
process study may yield the need for a much different pilot study than outlined in the
Study Plan. Adjusting the cost of the proposals for the cost of the testing and the
difference on the pilot study, Trussell will cost less ($298,375) than Malcolm Pirnie
(approximately $370,000). Staff recommends the modified proposal by Trussell
Technology, costing $199,393, which eliminates some of the testing in favor of
performing more compositing, and defers the pilot study recommended by the Study
Plan. The pilot study may or may not be required depending on the study results, and if
required, will in Trussell Technology's opinion, require modification from that
recommended by the Study Plan; requiring the solicitation of the pilot study at a later
date.
Summary and Recommendation:
Staff recommends accepting the modified proposal recommended by Trussell
Technology, Inc. in the amount of $199,939.
COMMISSION/BOARD REVIEW AND RECOMMENDATIONS:
This item will be presented to the Water Advisory Commission at its meeting of
September, 25, 2007. The comments of the commission will be presented orally.
FINANCIAL CONSIDERATIONS:
The projected budget for the analysis phase of this project is estimated at $250,000.
This amount covers that cost of the contract, plus approximately $50,000 is additional
staff, equipment and other expenses that may be necessary. For example, the
sampling requirements of the contract may result in the need for increased staff time
and/or temporary staffing. If no additional costs are needed these funds would no be
used. Additionally, the cost of this project is recommended to be funded from the
GWRP fund. Although the fund reserves may not be sufficient to fund the project, the
cash flow deficit can be covered from the capital replacement or debt service reserves
on a temporary basis.

If pilot testing of a developed solution is conducted, the cost of pilot testing phase may
cost an additional $100,000. The cost of implementing the ultimate solution is unable to
be determined at this time.

Re: Proposal to Provide Engineering Design Services for the Testing, Evaluation
and Recommendations Relating to Colored Water
Dear Mr. Bauman:
The purpose of this letter is to transmit our proposal prepared in response to your RFP,
dated August 13, 2007, requesting proposals to provide Engineering Design Services for
the Testing, Evaluation, and Recommendations Relating to Colored Water. Trussell
Technologies, Inc. is particularly pleased to submit a proposal in response to this RFP
because we believe this is a project that our organization is uniquely suited to perform.
Also, we want to personally thank you for the time you spent explaining the situation to
us and helping us understand San Juan Capistrano's needs. We have retained the services
of the Akel Engineering Group to assist us on the system modeling in Task 4. Tony
Akel's experience in this area is exceptional, and we are confident you will be pleased,
Colored water problems have plagued water utilities from the beginning of time. We feel
it is important to resolve these problems because they have a direct impact on consumer
confidence. At the same time, such problems are often not easily solved. The key to
success in resolving such problems is to determine their cause. As a result we support the
basic approach outlined in the RFP and, as you requested, we have prepared a scope of
work and an estimate designed to respond directly to the services described in the RFP.
At the same time we are proposing some changes to the approach detailed in the RFP in
the form of an optional scope. We believe these changes will save the City money and, at
the same time, improve the chance of success. They are based on our experience that
such color problems often result from gradual accumulation of iron and/or manganese in
the system over time, and show a poor correlation with the performance of the treatment
plant on any one given day. As a result we are proposing a unique application of
composite samplers; both at the treatment plant and in the distribution system to
simultaneously accomplish three objectives: a) find if there is a direct correlation between
treatment plant effluent quality, b) document conditions in the distribution system
throughout the year, and c) document the quality of all the streams in the treatment plant
so that efforts to troubleshoot the treatment process can be targeted where they will make
the most difference. In this regard, we propose sampling raw water header, the bypass
stream, the recycle stream, the RO stream and the final product water from the clearwell
so that all aspects of plant performance can be examined.

RE: Proposal to Provide Engineering Design Services for the Testing, Evaluation
and Recommendations Relating to Colored Water
We propose that, during normal weeks, a single week-long composite sample be prepared
for sites throughout the treatment plant and in the distribution system. This will give us a
complete record of all the inputs and outputs. So that this composite can be prepared, we
plan to save the composites from the first part of the week so they can be combined into
one composite at the end of the week. These stored samples create another opportunity.
When a colored water incident occurs, we will be able to analyze water throughout the
system and the treatment plant for several days before and after the incident. This
maximizes the likelihood that we will be able to identify any correlations to be found.
We save money but learn more.
It is also proposed that the budget for pilot studies be retained by the City until a time
when testing can be identified that will directly address the cause of the color problem.
Based on the information we've seen to date, there are three possible issues that might be
investigated at the treatment plant: a) poor performance of oxidants ahead of the
greensand filter (target of the pilot work proposed in the RFP), b) interference of recycled
wash water with the performance of the greensand filters (this was the problem in the
Camp Pendleton system where Trussell Tech is involved in a project to improve
performance), and c) poor performance of the RO in removing manganese (manganese is
now higher than anticipated during design). Desktop studies may show that pilot testing
is not required.
Trussell Tech has reviewed the sample Professional Services Agreement provided by the
City and is claiming no qNggptions to its standard terms and conditions. This proposal is
an offer valid for a 90 -day period.
We hope you find our proposal interesting and responsive. We assure you that if Trussell
Technologies, Inc. is selected to do this project you will receive the direct attention of the
principals of the firm.
Very Truly Yours

PROPOSAL TO PROVIDE ENGINEERING DESIGN SERVICES FOR THE TESTING, EVALUATION, AND
RECOMmENoAncNs RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
PROJECT UNDERSTANDING
The City of San Juan Capistrano (henceforth
referred to as the "City") has been receiving
persistent colored water complaints in its
distribution system. The City hired Malcolm
Pimie Inc. (MPI) to develop a Study Plan to
assess water quality issues associated with the
complaints. The proposed project
encompasses execution of the Study Plan as
written by MPL At the same time, the
proposed project will lay out an alternative
strategy to identify the source of the color and
to eliminate the colored water episodes. it is
our belief that judicious use of week-long
composite samples at several locations will
improve the chance of success. We also
propose that the City retain the budget for
pilot studies until a time when it is certain that
the testing to be conducted will directly
address the cause of the color problem.
BACKGROUND
Before providing background on the specific
problem being experienced by the City, it is
useful to provide a little background on the
experiences of other utilities with colored
water problems.
Colored Water. Colored water is a common
cause of consumer complaints and there are
many causes of colored water. The most
common example is the colored water that
occurs in the dead ends of almost every water
system. For most of the 201h century cities
with low alkalinity water (e,g. Portland, OR;
Tacoma and Seattle, WA; Boston, MA; New
York, NY; and Sydney, Aus.) experienced red
water complaints resulting from iron release in
cast iron mains. These same cities also
experienced blue and green water at the
consumer's taps due the action of the same
water on consumer plumbing. A few cities
have also experienced a blue water
phenomenon that has been attributed to the
action of bacteria on consumer plumbing (e.g.
EBMUD in Oakland, CA). Another common
problem is the red water after a municipality
changes from an uneblorinated deep well
supply to a chlorinated surface supply. This
happened in parts of Long Beach in the 1960s,
in Upland, CA in the 1970s and in Tucson, AZ
in the 1990s. Red water is also more common
in systems with high chloride water using cast
iron or ductile iron mains. Besides dead ends,
the most prevalent colored water problem
today is probably red water associated with
iron mains.
Yellow, brown or black water associated with
manganese is also a common problem. Some
confusion exists concerning acceptable levels
of manganese. EPA's secondary MCL for
manganese is 50 gg/L. Although keeping
manganese below 50 Ixg/L is usually adequate
to prevent staining of fixtures, lower levels are
required to prevent periodic occurrences of
colored water. Over the years, the quality of
the distribution systems has improved,
consumers have become accustomed to higher
quality water and more utilities are now
finding that very low manganese levels are
required to prevent consumer complaints.
When manganese is present in water entering
the distribution system, it deposits on pipeline
surfaces and, periodically the deposit comes
loose, making colored water. In 1960, A.
Griffen, Chair of the AWWA Task Group on
Manganese Deposition in Pipelines concluded
that a range of 10 to 20 lig/I could be safely
tolerated (Griffen, 1960). Thirty years later a
careful study was done in Brisbane, Australia
(Sly et al, 1990). This study reported that
consumer complaints were only eliminated
when manganese levels in the treatment plant
effluent were consistently less than 20 gg/L,
with an average level near 10 pg/L.

PROPOSAL TO PROVIDE ENGINEERING DESIGN SERVICES FOR THE TESTING, EVALUATION, AND
RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY Or SA14 JUAN CAPISTRANO
San Juan Capistrano. The City has historically
relied on imported water from the
Metropolitan Water District of Southern
California (MWDSC) as the primary source of
its drinking water. In order to decrease its
dependence on imported water, the City
retained ECO Resources Inc. to design, build,
and operate a Ground Water Recovery Plant
(GWRP) to treat groundwater from six wells:
Capistrano Valley Water District (CVWD-1),
Dance Hall, Kinoshita, San Juan Basin 2
(SJB-2), San Juan Basin 4 (SJB-4), and
Tirador.
Well water quality. The six wells serving the
GWRP have varying quality. Table I -I shows
the average turbidity, iron, manganese, and
TDS for each of the six wells based on
sampling conducted in 2004 along with the
design raw water quality (DRWQ). Iron and
manganese are highlighted because they often
cause color episodes in distribution systems.
Table 1-1 also shows the maximum
production that was anticipated from each
well. Table 1-1 shows that certain wells are of
considerably lower quality than others,
notably Dance Hall and Tirador. The report
by Boyle cited in Table 1-1 also noted one
well would be used as a stand-by well and that
not all wells would be used under typical
operation. The Boyle report also showed a
scenario where blending five wells would
result in a manganese concentration that
exceeded the DRWQ (Boyle 2004).
Based on the experience of ECO Resources in
operating the plant, it is known that the wells
were not capable of producing the anticipated
amount of water shown in Table 1-1 (Dreher,
2006). Therefore, it is possible that the
blending of well water may result in
conditions where the DRWQ for manganese is
exceeded. It has been observed recently that
the blended well water manganese
concentration has been higher than the
DRWQ, — 1.5 mg/L (Bauman, 2007). While
the blended well water manganese
concentrations have been higher than
expected, they are consistent over a period of
time and not subject to fluctuations that
correspond with the color episodes.
Therefore, the City believes the well water
quality, alone, is not likely the cause of the
intermittent color episodes (Bauman, 2007).
Description of the Groundwater Recovery
Plant (GWRP). The GWRP treats a portion of
the flow with reverse osmosis preceded by
conventional multimedia filtration
pretreatment. No oxidants are added upstream
of the RO process. The remaining portion of
the flow bypasses the RO and is treated by
oxidation followed by greensand filtration.
For the bypass stream, sodium hypochlorite is
added prior to the greensand filter to oxidize
the iron and potassium permarganate is added
to oxidize the manganese. Figure I -I shows a
simplified schematic of the GWRP process.
Figure 1-1 includes enough detail to describe
the issues related to the proposed project and
is not intended to show all details. For
example, certain chemical feeds are omitted
from Figure 1-1, such as the sodium bisulfite
added upstream of the RO, the caustic soda
added to the RO permeate, the free chlorine

ammonia and sodium hypochlorite added
downstream of the clearwell before the water
enters the distribution system. The numbers
that appear on Figure 1-1 correspond to
sampling locations, which will be discussed
later in the proposal.
Colored water complaints. The City has
received persistent colored water complaints
from residents since the GWRP began
operation in December 2004. A map of the
distribution system provided by the City
showed that in eight colored water episodes
since 2005, most of the customer complaints
occurred in the 250S pressure zone.
July 2005. A colored water complaint was
received in July 2005 that resulted in
operational changes to the GWRP. On July
17, 2005, the GWRP had a turbidity spike of >
1 .0 NTU that lasted for 12 minutes. During
the episode, customers were calling the City
complaining of "brown water." At the time,
the GWRP was not alarmed for turbidity
spikes (Dreher, 2005a).
Upon investigation, it was determined that
solids buildup in the washwater recovery
tanks was resulting in increased turbidity of
the clarified washwater recycle line that is fed
to the RO bypass greensand filters. In
essence, it was determined that the wasbwater
line was drawing from a layer. of high
concentration solid material at the bottom of
the washwater recovery tanks. In the short-
term, ECO began pumping out the higher
concentration material from the washwater
recovery tanks. For the long-term, ECO
instituted weekly flushing of backwash water
to the SOCWA wastewater plant and initiated
a program of visual inspection of the
backwash water tanks interior to determine if
buildup is occurring. Additionally, an alarm
was put in place to shut down the washwater
recovery pumps when turbidity in the RO
bypass filter effluent exceeds 0.2 NTU
(Dreher, 2005a).
September 2005. A colored water
complaint was received in September 2005
that resulted in additional changes to the
GWRP operating procedures. On September
23, 2005, a turbidity spike was observed in the
GWRP in the influent to the clearwell (see
Figure 1-1) with a duration of 1.5 hours and >
I NTU for 20 minutes (Dreher, 2006b).
In a letter from ECO's plant operator to
CDHS, it was noted that it was only the
second time since plant operations began that
colored water complaints were preceded by a
turbidity spike. it was also noted that "post
prior incidents have been related to
distribution system issues." (Dreher, 2006b).

RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
Additional modifications to plant operations
were made after this incident. The online
turbidimeter on the RO bypass stream had
been "active" only when the plant was in the
backwash recovery process. After the
incident, the RO bypass filter effluent
turbidity alarm was set to remain active 24n
and the plant's distribution pumps were set to
be shutdown by this alarm. After the July
2005 incident, a procedure was put in place to
waste the Fe/Mn solids sludge from the
bottom of the washwater recovery tanks
weekly. After the September 2005 colored
water episode, the frequency of this process
was increased to three times per week (MWF)
(Dreher, 2006b).
Evaluation of July and September 2005
Colored Water Episodes by MPI. The City
retained MPI to identify corrective measures
for water quality issues causing "customer
complaints of red and brown water resulting
from excessive levels of iron and manganese
concentrations in the distribution system
samples." MPI was also asked to evaluate
potential areas of concern regarding the
GWRP's ability to produce 4800 AFY (MPI,
2006).
The MPI evaluation corroborated the
observations made by ECO's plant operator
(Dreher, 2006a&b) that high turbidities in the
washwater recovery line contributed to the
elevated turbidities in the July 2005 and
September 2005 incidents of colored water. It
was reported that the online turbidity
analyzers for the RO bypass and blended RO
permeate/R0 bypass water samples had limits
of 10.0 and 1.0 NTU, respectively. In the July
and September 2005 incidents, these limits
were reached and actual turbidity values may
be higher than those reported for these
streams. MPI also reported that it is "highly
unlikely that RO membrane operation resulted
in the excessive turbidities observed in the
City's distribution system (MPI, 2006),
For the RO bypass treatment train, MPI
recommended installation of an online
turbidimeter on the washwater recycle line to
the RO bypass filter to continuously measure
turbidity and made several recommendations
involving GWRP operations. They also noted
that changes to plant operations that increase
"the. particulate and solids loading to the
filters, such as oxidizing and filtering the
complete plant flow or operating the
Backwash Recovery tanks in a less than
optimal manner for solid separation may
require construction of additional filters or
washwater recovery tanks (MPI, 2006).
In their evaluation, MPI also recommended
that ECO consider modifications for RO
pretreatment to remove iron and noted that
ECO is considering adding a sodium
hypochlorite feed to the entire plant flow
(sand separator influent) to oxidize iron and
remove it in the RO feed filters prior to the
RO and avoid problems with membrane
fouling. MPI also recommends that if this
strategy is followed, there are several concerns
that must be addressed (MPI, 2006):
• The RO feed filters may not be
adequately sized to handle the
increased loading and additional filters
may be needed
• The RO feed filters will need to be
backwashed more frequently, resulting
in more wastewater to the washwater
recovery tanks and possibly a need for
additional tankage
• The sodium hypochlorite may come in
contact with the RO membranes and
damage them so careftil evaluation of
the sodium bisulfite feed system to
avoid this potential problem is needed.
• Manganese is not likely to be fully
oxidized by the sodium hypochlorite,

but it may be partially oxidized and
could foul the RO Membranes.
Based on the raw data in Attachment A of
MPI (2006), Trussell Tech constructed a
probability plot of average RO Feed
conventional filter effluent compared to
average RO Bypass greensand filter effluent
for the period June through September 2005.
As shown on Figure 1-2, the RO bypass
greensand filter produces a lower effluent
turbidity than the RO feed conventional filters.
This suggests that a strategy to oxidize iron in
the complete plant flow and increase the
loading of the RO feed filters may indeed
require the installation of additional RO Feed
filters.

EVALUATION OF THE COLORED WATER
PROBLEM AND POSSIBLE APPROACHES
TO SOLUTION
The Tasks as laid out in Exhibit A by MPI
will probably resolve the colored water
problem, but Trussell Tech believes that, if
some modifications are made to this approach,
the chances of success can be improved and
the cost of the project can be reduced.
Concepts Behind the Optional Approach, The
following four tasks were laid out in Exhibit
A:
I . Task I — Sampling
2. Task 2 — Evaluation of Treatment
Alternatives
3. Task 3 — Optimization of GX�W
Processes
4. Task 4 — Optimization of Distribution
System Operations
Trussell Tech. would like to suggest
modifications to Tasks I and 2. As it is
currently specified Task I would collect daily
samples at three points in the distribution and
at the following locations at the treatment
plant: a) the blended well water, b) the bypass
water, c) the recycle water, and d) the product
water.
Optional Approach to Sampling. The
optional approach would collect composite
samples at the same locations daily. More
intensive surveys would be conducted if a
color incident occurs in the distribution
system.
Trussell Tech suggests that composite
samplers be installed at the following
locations -
1. Three locations in the distribution system
2. The blended well water (point "I" on Fig. 1-1)
3. The washwater recycle line
(point "5" on Fig. 1-1)
4. The Bypass line (point "2" on Fig. 1-1)
5. The RO effluent (point "Y on Fig. 1-1)
6. The product water exiting the clearwell
(point "4" on Fig. 1 -1).

RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
Five sample bottles will be purchased for each
of the composite samplers, one for each day of
the work week. Each day, the oldest
composite sample will be thrown away at each
site and the bottle reused. As a result, there
will always be four earlier samples as well as
the sample for the current day at each sample
site. At the end of each week, an aliquot will
be taken from the composite sample for each
day and poured into one sample bottle for
each site, provided by the laboratory - to
create one overall composite sample for each
sample site for the week. This approach
provides a complete characterization of plant
performance and of conditions in the
distribution system, but it reduces the sample
load by 90 percent.
When an incident occurs and color complaints
are made, the four previous samples will be
analyzed as well as sample for the day of the
incident as well as the samples for the
following two days. As a result we will have
sound data on the overall long-term conditions
at all sample sites as well as a specific daily
record before and after each incident. Equally
important samples before and after the
incident can be preserved for future analysis
should questions arise.
Optional Approach to Pilot Work.
Trussell Tech also recommends that a decision
to conduct the pilot work proposed in Task 2
be postponed until the completion of the
oxidants analysis in Task 2, the optimization
analysis in Task 3 as well as the first 4-6
months of the sampling program as well as
preliminary work on Task 4. This will put the
team in a strong position to judge the cause of
the colored water problem, to understand the
part of the plant that is not meeting the city's
needs and if piloting is necessary to address
the problem.
Trussell Tech believes the decision to pilot
preoxidants is premature at this time for the
following reasons:
1) Piloting is expensive and should only be
conducted if there are identifiable
benefits.
2) The Chlorine-permanganate-greensand
approach used on the bypass stream at
the GWRP is accepted as the state of the
art for the removal of iron and
manganese and it is successfully used
throughout the country.
3) There is a reasonable possibility that
other problems at the GWRP are
responsible for the color problem and it
is not clear that an oxidants pilot study
would resolve these. Examples are a)
the possibility that the washwater
recycle, while improved, is still
interfering with performance and b) the
possibility that the RO membranes in the
GWRP, which have been cleaned many
times an which are constructed with no
brine seal, are contributing to the
problem.
4) The use of an oxidant on whole flow
may void RO membrane warranty.
Boyle proposed greensand treatment for
the whole flow during the original
design but was forced to change to
conventional filters before RO and avoid
oxidants in order to gain the cooperation
of the RO manufacturer.
5) There is very limited or no turbidity data
for the RO permeate and the washwater
recovery streams and very limited iron
and manganese data for any streams
other than the raw water and product
water. This data is essential for the
analysis of possible treatment solutions.
6) Until the sampling, source tracking and
flushing studies are completed it is not
certain that improving oxidation at the
GWRP is the most cost-effective means
of solving the color problems.

Approach to Hydraulic Modeling. A hydraulic
model, developed based on information
extracted from the City's existing GIS shape
files for the 250 pressure zone, will be the
central too] for the source tracing task.
Hydraulic pathways from and to the 250
pressure zone will be considered to establish
the boundary conditions and bypass modeling
the entire City-wide system at this time.
Sources of water at the locations of elevated
iron and manganese occurrence within the
distribution system will be determined. The
intent of this task is to determine if the
complaints are resulting from the operation of
the treatment facility or due to operation of
certain distribution system infrastructure,

PROJECT APPROACH AND SCOPE
OF SERVICES
The project approach and scope of services
will build upon the logic laid out in the Project
Understanding (Section 1). The scope will
encompass execution of all the Tasks as laid
out in Exhibit A of the RFP. In addition, an
optional approach to Task I and Task 2 will
be included that Trussell Tech believes will
result in a determination of the cause of and
the solution to the colored water episodes at a
cheaper cost to the approach defined in the
RFP.
TASK 1 — SAMPLING OF THE RAW
WATER, GWRP TREATED WATER AND
AT THE DISTRIBUTION SYSTEM
The purpose of Task I is to collect regular
monitoring data from the raw water, from
various locations in the GWRP, and from the
distribution system to aid in determining the
source, cause, and extent of the colored water
problems. Table 2-1 shows the deliverables;
for Task I broken down by sub -tasks. The
scope of services for Task I will be described
below for both the approach described in
Exhibit I of the RFP and the optional
approach recommended by Trussell Tech.
Approach in the RFP. The scope of services
for the approach laid out in the RFP is
described below. As shown in Table 2-1, a
sampling plan and database for storing sample
data will be developed before sampling
begins. In addition, operators will be briefed
on the sampling plan so they will be prepared
to take the samples. A local lab was contacted
in preparation of the project budget so the
seeds of developing a sample collection and
preservation protocol have been planted.

Task I A Influent Water. As shown in
Table 2- 1, grab samples for the influent water
for the constituents shown in Table 2-1 will be
collected daily (5d1wk) at varying times
throughout the day over a 12 -mo. period. As
an alternate approach, composite samples will
be collected daily (5d/wk) over a 12 -mo.
period.

Task I B GWRP Treated Water Sampling.
As shown in Table 2-1, the GWRP treated
water will be sampled for the constituents
shown in Table 2-1. Samples will be collected
daily (5d/wk) at varying times throughout the
day over a 12 -mo. period. As an alternate
approach, composite samples will be collected
daily (5d/wk) over a 12 -mo. period.
Task I C Additional Sampling when
Turbidity Spikes or Colored Water is
Reported. An intensive plan for sampling the
Plant when turbidity spikes > 0.3 ntu or when
colored water is reported will be developed.
Based on past online turbidemeter data and on
the historical record of color complaints, 20
such events were included in the project
budget. The constituents to be sampled and
the sample locations in the GWRP are shown
in Table 2- 1. The preliminary plan, to be
revisited before the sampling begins, is to
have the operators sample at each sample
location in the Plant four times per day for the
day a color event is reported and also the
following day for a total of eight samples.
Task ID Distribution System Sampling
when Turbidity Spikes or Colored Water is
Reported. An intensive plan for sampling the
distribution system when turbidity spikes >
0.3 ntu or when colored water is reported will
be developed. Based on past online
turbidemeter data and on the historical record
of color complaints, 20 such events were
included in the project budget. The
constituents to be sampled and the protocol for
sample locations in the distribution system, to
be determined before sampling begins, are
shown in Table 2-1. The preliminary plan, to
be revisited before the sampling begins, is to
have the operators sample at each sample
location in the distribution system two times
per day for the day a color event is reported
and also the following day for a total of eight
samples.
As an alternate approach, a composite sampler
will be placed in the distribution system at a
location to be determined before sampling
begins. The composite samples will be
analyzed for the constituents shown in Table
2-1. The preliminary plan, to be revisited
before sampling begins, calls for samples to
be collected under the same procedure as for
the distribution system grab sampling (2X/d
for the day of and day following an event).
Optional Approach Recommended by Trussell
Tech. As discussed in the Project
Understanding (Section 1), Trussell Tech
recommends an optional approach to meet the
objectives of the Task I Sampling at a cheaper
cost to the sampling prescribed by the RFP.
The optional approach would collect
composite samples at the same locations daily.
More intensive surveys would be conducted if
a color incident in the distribution system.
Trussetl Tech suggests that composite
samplers be installed throughout the GWRP
and in the distribution system (locations to be
described in the sub -sections below).
Sampling Protocol for the Optional
Approach Recommended by Trussell Tech.
The protocol for sampling is as follows. Five
sample bottles will be purchased for each of
the composite samplers, one for each day of
the work week. Each day, the oldest
composite sample will be thrown away at each
site and the bottle reused. As a result, there
will always be four earlier samples as well as
the sample for the current day at each sample
site. At the end of each week, an aliquot will
be taken from the composite sample for each
day and poured into one sample bottle for
each site, provided by the laboratory - to
create one overall composite sample for each
sample site for the week. This approach

RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
provides a complete characterization of plant
performance and of conditions in the
distribution system, but it reduces the sample
load by 90 percent.
When an incident occurs and colored water is
reported, the four previous samples will be
analyzed as well as sample for the day of the
incident as well as the samples for the
following two days. As a result we will have
sound data on the overall long-term conditions
at all sample sites as well as a specific daily
record before and after each incident. Equally
important samples before and after the
incident can be preserved for future analysis
should questions arise. Based on the historical
record, the fee proposal is based on six
colored water incidents being reported during
the one-year sampling program time frame.
Task IA Influent Water. A composite

Reported. Composite samplers will be
installed at the following locations.
7. Three locations in the distribution system, to
be determined during preliminary planning.
Samples will be collected and analyzed
according to the protocol described above.
TASK 2 — EVALUATION OF TREATMEN-1
ALTERNATIVES
As stated in Exhibit I of the RFP, "this task
wil I evaluate alternatives for treatment of
colored water. Assuming that colored water is
caused by the presence of iron and manganese
in the water, oxidation followed by filtration is
the most preferable solution. Treatment
alternatives will be evaluated in this task
assuming that GWRP operations will not be
altered in response to an iron or manganese,
spike in the raw water." An optional approach
to this task is recommended by Trussell Tech
in which the pilot study (Task 2.A.b) will not
be conducted at this stage of the project for
reasons discussed in the Project
Understanding (Section 1).
Approach in the RFP. The deliverables fbi
Task 2 are summarized in Table 2-2.

PROPOSAL TO PROVIDE ENGINEERING DESIGN SERVICES FOR THE TESTING, EVALUATION, AND
RECOMMENDATIONS RELATING TO COLORE:O WATER FOR THE CITY OF SAN JUAN CAPISTRANO
Each sub -task will be described below.
Task 2A - Pre-tTeatment Alternatives
Evaluation. This task will consider addition
of an oxidant chemical to the blended well
water to oxidize iron and/or manganese for
subsequent removal in the GWRP by the RO
bypass filters or the RO feedwater filters.
Task 2A.a Desktop Study. As shown
in Table 2-2, this sub -task will analyze several
alternative pre -oxidants for the oxidation of
iron and manganese including free chlorine
and chlorine dioxide. The results will be
summarized in a letter report selecting one
pre -oxidant for further consideration in the
project.
Task 2A.b Pilot Study. The selected
pre -oxidant from Task 2.A.a will be tested in a
pilot study to demonstrate its applicability for
iron and manganese removal. The pilot study
will be performed for a period of 3 months
and is to be conducted on a side -stream of
blended well water prior to its entry to the
GWRP. After addition of pre -oxidant to
remove iron and manganese, the blended well
water will be treated by a temporary
greensand filter in the pilot study to remove
precipitated iron and manganese. The fee
proposal includes rental of a greensand filter,
time for a Trussell Tech engineer to setup the
pilot study and assist the operators in running
the pilot experiment, and budget for laboratory
analysis of iron and manganese (total and
dissolved) in the feed and downstream of the
greensand filter. The pilot study will run 24/7
as intermittent operation will introduce
reactions that will not be present during full-
scale operation and potentially compromise
the results. The deliverables for Task 2.A.b
are summarized in Table 2-2.
Task 2A.c Conceptual Design and
Layout. Varous Trussell Tech engineers have
extensive experience with conceptual design
and layout. In this sub -task a conceptual
design and layout for the selected alternative
oxidant will be performed.
Task 2B Post-treatment Alternatives
Evaluation. Another alternative approach to
reduce iron and manganese levels entering the
distribution system is to Post -treat the GWRP
treated water with an oxidant feed followed
by filtration. As shown in Table 2-2, the
deliverable will be a desktop study of post-
treatment alternatives.
Task 2C - Conceptual Level Cost
Estimation. As shown in Table 2-2, the
deliverable is a Level 4 (-30%,+50%) cost
estimate for the selected pre-treatment (from
Task 2A) and post-treatment (from Task 213)
alternatives. The Trussell Tech engineers
participating in this project have broad
experience with Level 4 cost estimates.
Optional Approach Recommended by Trussell
Tech. Trussell Tech recommends that a
decision to conduct the pilot work proposed in
Task 2 (Task 2A.b) be postponed until the
completion of the oxidants analysis in Task 2,
the optimization analysis in Task 3 as well as
the first 4-6 months of the sampling program
as well as preliminary work on Task 4. This
will put the team in a strong position to judge
the cause of the colored water problem, to
understand the part of the plant that is not
meeting the city's needs and if piloting is
necessary to address the problem. Trussell
Tech believes the decision to pilot preoxidants
is premature at this time for the reasons stated
in the Project Understanding (Section 1). As a
part of the optional approach recommended by
Trussell Tech discussed in Task 1, the fee
proposal includes this strategy of not
conducting the pilot study as a part of this
project as an element of the optional approach.

TASK 3 — OPTIMIZATION OF GWRP
PROCESSES
The purpose of Task 3 is to optimize the
performance of the GWRP for better removal
of iron and manganese. According to Exhibit
I of the RFP, "the premise of this task is that a
well operated system such as the one at
GWRP should be capable of effectively
removing iron and manganese from the well
water, which is anticipated to be the source of
colored water complaints." The deliverables
for Task 3 are summarized in Table 2-3.
TASK 4 — OPTIMIZATION OF
DISTRIBUTION SYSTEM OPERATIONS
Table 2-4 presents a list of deliverables for
Task 4. Each sub -task will be described in
detail below.
Task 4A Evaluation of the 250 Zone
Operational and Functional Conditions. The
purpose of Task 4A is to assess water quality
conditions in the 250 pressure zone because
most of the colored water problems have been
associated with the 250 pressure zone. There
is a concern iron valves and other fixtures in
the distribution system may be subject to
corrosion and contributing to the colored
water episodes. The 250 pressure zone also
includes the older part of the City and there
may be unlined iron pipe in the distribution
system though the City has stated that the
colored water reported by consumers is not
typically associated with the older parts of the
250 pressure zone (Bauman, 2007). Water
samples will be collected at the frequency, in
the locations, and for the constituents
described in Table 2-2 in order to assess the
potential for corrosion contributing to the
colored water episodes. Trussell Tech
engineers have a unique expertise in this
particular area,

Task 4B - Source Tracing. Task 4B will be
divided into six sub -tasks discussed below.
Task 4B I Meetings, Data Collection, and
Task Management. This task includes project
meetings, data collection, task management,
meeting agendas, and monthly progress
reports.
Task 4132 Seasonal Demand Analysis and
Geocoding from Water Billing Records.
Monthly City-wide production records for the
past 5 years will be evaluated to determine the
seasonal demand variations within the City.
The objective is to identify the maximum day
demands, typical average day demands, and
the low winter demand periods. Water age
tends to be a factor during the low demand
periods. In this task, water demand peaking
factors will be recommended.
The billing records will be normalized and
geocoded to the model junction nodes within
the 250 pressure zones This methodology
provides a more accurate distribution of
demands for modeling purposes. Though this
task will focus on the pressure zone 250, this
same methodology can be used by the City to
complete the assembly of the entire
distribution system, following the completion
of this project.
Task 4133 Hydraulic Model Development
from GIS and from Input/Output Location
Information. The City has invested in a GIS
that includes the water distribution system and
its appurtenances. The 250 pressure zone
includes approximately 15,000 pipes, 5,300
valves, and 1,700 hydrants.
The GIS shapefiles will be exported to the
hydraulic model. The project team is equally
competent with commercially available
hydraulic models including MWHSoft
H20NET, H20MAP Water, and Infowater, as
well as Bentley's WaterGEMS.
It is our understanding that City staff currently
own an H20MAP water license. Since the
hydraulic engine contained in these software
packages are identical, our team proposes to
perform the analysis using a software most
preferred by City staff. A long term City goal
may be to build on the 250 pressure zone
model and assemble a City-wide model that
will be maintained by City staff. During the
kickoff meeting we will discuss the benefits of
using H20MAP Water, currently owned by
the City, versus Infowater which runs inside
ArcMAP.
Since the 250 pressure zones is interconnected
to other pressure zones, the boundary
conditions consisting of water flowing into
and out of this zone, are exceptionally
important. Historical and seasonal operational
data for water entering and leaving this zone
will be collected from the SCADA system.
The intent is to simulate realistic boundary
conditions for the demand scenarios that will
be used for the source tracing task.
Task 4B4 Hydraulic Model Calibration to
SCADA and optional Pressure Monitors.
Calibration provides a measure of confidence
in the model simulated results. SCADA data
will be used to calibrate the boundary
conditions, including the operations of pump
stations and storage reservoirs influencing this
pressure zone. Calibration within the
distribution system of the 250 pressure zone is
an optional, though desired task. This task
involves installing up to 6 pressure loggers at
critical locations within the distribution
system and monitoring pressures for a period
of one week. This task assumes the pressure
loggers, if available, will be installed by the
City's operation staff.
The model will be calibrated for the extended
period simulation, using the data available
from SCADA and the optional pressure
loggers.

RECOMMENDATIONS RELATING TO COLORED WATER FOR THE CITY OF SAN JUAN CAPISTRANO
Task 4135 Source Tracing. In this task, the
model will be used for the source tracing
simulations. Water age through the
distribution system will be mapped for
average day demand, maximum day demand,
and minimum winter day demand. The
model will be used to monitor the area of
influence from each source entering the 250
pressure zone and from the storage reservoirs.
The focus of the analysis will be the areas of
elevated iron or manganese occurrences
within the distribution system.
The preliminary analysis results will be
presented to City staff for discussions and for
evaluating further analysis scenarios. The
team feedback will be used to model the final
scenarios, draw conclusions, and develop
recommendations.
Task 4136 Technical Memorandum. A
technical memorandum will document the
hydraulic model development, calibration, and
modeling.
Task 4C - Evaluation of Flushing Program.
The team will evaluate the existing flushing
program utilized by the City. The hydraulic
model will be used to assist the project team in
evaluating opportunities for improving
delivery of fresh water at various distribution
system locations. Various possibilities will be
considered including unidirectional flushing.
OPTIONAL TASK A — FINAL REPORT
The scope and deliverables discussed above
include all those prescribed by the RFP. An
Optional Task A (OT -A) is included in the
Fee Proposal for a final report to present the
results all four tasks simultaneously.
