Freese and Nichols, Inc. is very pleased to respond to the:
REQUEST FOR PROPOSALS FOR A PRODUCTION STUDY OF THE
WATER TREATMENT PLANT OF THE CITY OF PARIS, PARIS, TEXAS.
The Federaf Safe Drinking Water Act (SDWA), the first national regulation to
establish uniform standards for all water systems, was enacted in 1974. The SDWA
has been highly effective in protecting public health and has evolved tarespond to
new and emerging threats to safe drinking water. In 1993, a Crytosporidium
outbreak in Milwaukee caused:
➢ 400,000 people to experience intestinal iliness
➢ More than 4,000 to be hospitalized
➢ At least 50 deaths
There have also been crytosporidosis outbreaks in Nevada, Oregon, and Georgia
over the past several years. Amendments to SDWA in 1996 required EPA to develop
rules to balance the risks behueen microbial pathogens (Interim Enhanced Surface
Water Treatrnent Rule-IESWTR) and disinfection byproducts (Disinfection Byproduct
Rule-DBPR). These rules strengthen the protection against microbial contaminants,
especially Crytosporidium, and reduce potential health risks of disinfection
byproducts.
SIMULTANEOUS AND COMPETING REGULATIONS...
The SDWA has promulgated various drinking water regulaflons which require
simultaneous compliance. Some of these competing regulations direcHy conflict with
each other. The EPA has attempted to balance the competing regulations through its
microbial-disinfectants/disinfection byproduct (M-DBP) approach. The more
significant rules are:
➢ Interim Enhanced Surface Water Treatment Rule: Filter performance,
reduce allowable filter turbidity from 0.5 to 0.3 NTU's, disinfection profiling
PI:[ 13C • NiC HOLS

-
and benchmarking provisions, and 2-Log Cryptosporidium removal
requirements.
➢ Stage 1 Disinfectants and Disinfection Byproducts Rule (DBPR):
Requires specified removal of Total Organic Carbon (TOC), requires
reduction in total trihalomethanes (TTHM) from 100 ug/L to 80 ug/L and
add Haloacetic acids (five) (HAA5)
➢ Total Coliform Rule: May increase disinfectant amounts (competes with
DBPR)
➢ Lead and Copper Rule: May increase pH levels in distribution system
(competes with IESWI'R & DBPR)
Beginning January 1, 2002, all surface water treatrnent plants serving at least 10,000
people will be required to meet the IESWR and the Stage 1 D/DBPR. The Total
Coliform Rule and the Lead and Copper Rule are now in effect. The EPA has
proposed the Stage 2 Disinfectants/Disinfection Byproducts Rule (D/DBPR) and the
Long-Team 2 Enhanced Surface Water Treatrnent Rule (LT2ESWI'R). These rules
will require more thorough monitoring and treatrnent.
Treatrnent plants should consider a variety of compliance options. Including capacity
reduction, or seasonal capacity reduction to meet more stringent requirements,
optimization of treatrnent, altemative compliance criteria, exceptions, chemical and
physical modification, and operational changes.
We have confidence in our ability to identify the appropriate compliance strategies
for current and future regulations based on our fo((owing qualifications:
• Recent (1999/2001) Safe Drinking Water Act and Plant Production
Evaluations for:
➢ Ciiy of Beaumont
➢ Brown County Water Improvement District #1
vVater Treatment Plant Production Siudy
➢ City of Clebume
➢ City of Fort Worth
➢ Greenbelt Municipal and Industrial Water Authoriiy
➢ City of Grapevine
➢ City of Longview
A summary of the Safe Drinking Water Act [mplementation studies for Grapevine,
Greenbelt and Longview wiit be presented at Texas Water 2002 conference in San
Antonio. -
• Extension of City Staff
Freese and Nichols maintains close working relationships with plant staff through
workshops and training sessions. We maintain cunent involvement with water utility
associations and state and federal regulatory agencies allowing us to accurately
idenfify and forecast changes in upcoming regulations, as well as the implementation
of new regulations.
• Optimization and Treatability Laboratory
Freese and Nichols is one of a very few firms that maintains an in-house water
treatrnent laboratory capable of conducting chemical optimization, treatability
testing, settling testing and a variety of other specialty testing. Freese and Nichols is
the only consuttant who conducts real-time tracer studies for CT compliance.
This capability allows Freese and Nichols to have the analytical equipment to
accurately access and predict specific plant performance objectives from chemical
optimizafion through the newest technology innovations.
We are eager and enthusiastic regazding the opportunity of working
with the City of Pazis on this important assignment and in establishing
a long-term relationship.

Water Treaiment Plant Produdion Study
Following World War 1, Major Hawley retumed to Fort Worth and resumed
his engineering practice in 1919. One of his first notable posiwar pmjects was
to study and report on a new $1 million municipal water supply for the City
of Paris.
"After months of collecting and examining rainfall records and other data,
Hawley recommended a dam and reservoir on Pine Creek to impound a
surface water supply of 3.9 billion gallons (12,000 acre-feet), enough to meet
the needs of the present and for a generation to come." - A Century in the

WATER TREATMENT PLANT DESIGN AND IMPROVEMENTS
BROWN COUNTY WATER IMPROVEMENT DISTR[CT
Freese and Nichols first designed the Brown Couniy W[D water heatrnent plant in
1986. The innovative treatment process used at Brown County WID's 10 MGD
treatment plant employs iube settlers in the ctarification basins, which allow
treatment at a higher rate than a conventional basin of comparable size by
shortening the settling distance and improving flow distribution. The tube settlers
provide enhanced turbidity removal. Clarification is preceded by rapid mixing and
flocculation and foflowed by filtration in dual media gravity filters with air/water
backwash. Operations are simplified by splitting influent flow evenly behueen filters
in service and utilizing the increased head loss concept to signal backwash
requirements, rather than using rate of flow controllers for filters.
A site selection analysis was made to determine that the site near the original facility
was preferable to other locations on the north and east sides of Brownwood. Freese
and Nichols also administered construction for the project, which was completed in
1986 at a cost of approximately $3.7 million. _
Following an evaluation of the plant conducted in 1991, Freese and Nichols
designed improvements to the plant and provided construction management
services.
CunenUy, Freese and Nichols contracted to condud an uprating evaluation for the
water treatrnent plant. The purpose of the evaluation is to determine if the plant can
be rated at a higher capacity (20% increase) while still meeting SWDA requirements..

SAFE DRINKING WATER ACT IMPLEMENTATION
GAEENBELT MUNICIPAL & INDUSTRIAL WATER AUTHORITY
Freese and Nichols, Inc was authorized by the GMIWA to assist the Authority in
conducting a plant evaluation to meet the Stagel Disinfection Byproduct Rule (Stage
1 DBPR) and Interim Enhanced Surface Water Treahnent Rule (IESWTR). The
Stage 1 DBPR and IFSWfR were promulgated on December 16, 1998 and the
compliance date for both regulations is set for the GMIWA on January Ol, 2002.1'he
IESWTR sets more stringent turbidity limits in the finished water to reduce the risk of
Cryptosporidium outbreaks in the distribution system. Also, continuous turbidity
monitoring for each filter is required by the IESWTR. The Stagel DBPR lowers the
existing total trihalomethanes (TTHMs) limit and set a new limit for haloacetic acids
(HAAs). [n addition, depending on raw water qualiiy, certain percentages of total
organic carbon (TOC) removal are required by this rule.
A principal area investigated with respect to TOC removal was the basic chemical
treatrnent process, coagulation using femc sulfate and alum. Promulgated Stagel
DBPR would likefy require the GM[WA WTP plant to operate in AEnhanced
Coagulation@ mode, increasing the cost of operation and possibly making turbidity
removal more difficult. The purpose of enhanced coagulation is to remove higher

The raw water SWA number was below 2 Umg-m in every quarter, which indicates
that raw water TOC is mosUy non-humic (not amenable to coagulafion) in nature.
These results are consistent with the jar test results, which show that the raw water
TOC is not amenable to coagulation. The GMIWA WTP met the specified TOC
removal in every quarter by meeting the raw water SWA excepfion criteria.
The TTHM and HAAS concen4ations in the raw water, and in the Simulated
Dishibution System testing indicate that GMIWA's cunent method of disinfection
(free chforine as a disinfectant in the treatrnent plant and in the distribution system)
resufts in TTHM and HAA5 concentrations in excess of those allowed by the Stage 1
Disinfection/Disinfectant Byproduct Rule. The Simulated Distribution System tesflng
also indicated that these concenirations can be lowered to acceptable leveis by using
chloramines for disinfection in the distribution system.

SAFE DRINKING WATER ACT COMPLIANCE
CITY OF LONGVIEW
Freese and Nichols, Inc. was authorized by the City of Longview to conduct
treatrnent plant evaluations for the Sabine Water Treatrnent Plant (16 MGD) and the
Cherokee Water Treatrnent Plant (27 MGD) in order to meet the newly promulgated
Stage 1 Disinfection Byproduct Rule (Stage 1 DBPR) and Interim Enhanced Surface
Water Treatrnent Rule (IESWTR); especially the TOC removal requirement of the
DBPR. The Stage 1 DBPR and IESWfR were promulgated on December 16, 1998
and the compliance date for the City of Longview for both regulations is January Ol,
2002. The IESW'I'R sets more stringent turbidity limits in the finished water to reduce
the risk of Cryptosporidium outbreaks in the disfibution system. Also, continuous
turbidity monitoring for each filter is required by the IFSWT'1?. The Stage 1 DBPR
lowers the exisfing total trihalomethanes'(TTHM) limit and set a new limit for
haloacetic acids (HAAs). In addition, depending on raw water quality, a certain
percent of total organic carbon (TOC) removal is required by this rule.

The purpose of this report is to present the final results of enhanced coagulation and
ozonation pilot testing for all four quarters of testing.
SUMMARY OF TESTING RESULTS
Enhanced Coagulation Testing
♦ The STEP 1 TOC removal requirement for both plants is 45% for all quarters
of testing.
♦ Of the six exception criteria, only the raw water SWA exception was met in
the first two quarters at the L.ake Cherokee WTP. Therefore, both plants were
required to meet either a STEP 1 or STEP 2 TOC removal requirement.
~ The enhanced coagulation testing shows that the City was required to add
hom 30 mg/L. to 60 mg/L of alum to meet eithez the STEP 1 or STEP 2 TOC
removal requirement at the Sabine plant. Typical alum dosages used at this
plant range from 30 mg/L to 70 mg/L..
~ The Cherokee plant met STEP 1 TOC removal requirement (45%) with an
alum dose of 47.5 mg/L. in the third quarter. All other quarters required alum
dosages of 30 mg/L to 50 mg/L to meet the Step 2 criteria. Typical alum
dosages at this plant range from 20 mg/L to 30 mg/L.
41 At both W"I'Ps, all coagulating chemicals produced settled water with
acceptable turbidity and apparent color levels. In the four quarters of testing,
no one coagulation chemical consistently ouiperfonned the others in color
removal. In tettns of turbidity removal, there were no significant performance
differences between alum, Polymer Blend A and Polymer Blend B at both
plants.
Ozonation Pilot Testing
♦ At the Cherokee plant, preozonation slighUy improved turbidity removal.
Preozonation at the Sabine plant provided results ranging from no
improvement to slight improvement.
~ At both plants, preozonation (with coagulation, flocculation and
sedimentation processes) improved color removal. Preozonation alone
(without alum) destroyed 37% to 65% of the color at the Cherokee W7'P.

Color removal by preozonafion alone was significanUy lower at the Sabine
plant (6.3% to 12.7%).
~ Preozonation alone did not improve TOC removal. The TOC levels in the
non-ozonated and ozonated settled water were approximately the same.
However, it is anticipated that the TOC removal at the full-scale ozone plants
will improve because of additional TOC removal in the biological filters.
Ozone conditions water so that biological growth can occur in the filters.
~ Preozonation controlled chlorination by-product (TTHMs and HAAs)
formation. It is very likely that the City's finished water TTHM and HAAs
levels would be below 0.04 and 0.03 mg/L., respectively if preozonation
facilities are installed at both plants.
~ The threshold odor numbers (TON) were not reduced significantly at both
plants due to preozonation. However, the odor of water changed due to
preozonation (from gYassy/slighUy musty to disagreeable at the Sabine WTP;
from musty/fishy to disagreeable at the Cherokee WTP).
♦ At each plant, no significant levels of bromate were fonned.

WATER TREATMENT PLANT EXPANSION
CITY OF GRAPEVINE
The Grapevine Water Treatrnent Plant cunenUy pzovides water to approximately
18,000 city residents. An expansion completed in 1990 enables the plant to treat up
to 8.0 MGD.
The original facility, constructed in 1959, had a capacity of 1.0 MGD. An expansion
in 1980 and a variance granted by the Texas Natural Resource Conservation
Commission (TNRCC) in 1987 raised the plant's capacity to 4.0 MGD. The 1990
expansion then doubled the plant's capaciiy to 8.0 MGD. The existing facilities were
also refurbished to improve the overall appearance of the plant. Freese and Nichols
designed the original ptant and subsequent expansions.
Freese and Nichols, Inc. (FNI) was authorized by the City of Grapevine to conduct
freatrnent plant evaluations for meeting the newly promulgated Stage 1 Disinfection
Byproduct Rule (Stage 1 DBPR) and Interim Enhanced Surface Water Treatrnent
Rule (IESWTR), especially the Total Organic Carbon (TOC) removal requirement of
the DBPR. The Stage 1 DBPR and IESWTR were
promulgated on December 16, 1998 and the compliance
date for the City of Grapevine for both regulations is
January Ol, 2002. The IESWI'R sets more stringent
turbidity limits in the finished water to reduce the risk of
Cryptosporidium outbreaks in the distribution system.
Also, continuous turbidity monitoring for each filter is
required by the IFSWTR. The Stage 1 DBPR lowers the
existing total trihalomethanes (T"fHM) limit and set a new
limit for haloacetic acids (HAAs). In addition, depending
on raw water quality, a certain percent of TOC removal is
required by this rule.
A principal area investigated with respect to TOC removal
was the basic chemical treatrnent process, coagulation
using alum, and femc sulfate. Promulgated Stage 1 DBPR
would require the City of Grapevine to operate in
IRI.L51.-MCHOLS'
Wnier Treatment Plunt Production Study
"Enhanced Coagulation" mode, increasing the cost of operation and possibiy
making turbidiiy removal more difficult. The purpose of enhanced coagulation is to
achieve higher percentages of TOC removal and reduce disinfection byproducts such
as TTHMs and HAAs.
The second area of the study was preozonation evaluation, assessing the potential
following benefits in water treatrnent:

The purpose of this report was to present the final results of enhanced coagulation
and ozonation pilot testing for all four quarters of testing.
SUMMARY OF TESTING RESULTS
Enhanced Coagulation Testing
lb The STEP 1 TOC removal requirement was 35% for a(I quarters of testing.
The STEP 2 removal requirement by ferric sulfate in the second quarter
(16.5%) is based on the TOC removal vs. coagulant dose cunve.
♦ Of the eight exception criteria, only the raw water SWA excepfion was met
in the first two quarters at the Grapevine WfP. Othenvise, the plant was
required to meet either a STEP 1 or STEP 2 TOC removal requirement.
♦ The enhanced coagulation testing shows that the City was able to meet the
STEP 1 TOC removal requirement in the last two quarters by adding from 60
mg/L to 95 mg/L of alum. In the first huo quarters, Alum was unable to meet
either the STEP 1 or the STEP 2 removal requirements. A high dose (95
mg/L) of ferric sulfate met the STEP 1 removal requirement in the first
quarter, and a ferric sulfate dose of 38 mg/L. met the STEP 2 removal

requirement in the second quarter. Ferric sulfate continued to ouiperfonn
Alum in removing TOC in the third and fourth quarters. Typical alum
dosages used at this plant range from 65 mg/L to 70 mg/L. A low dose (0.5
mg/L) of polymer is also used at the Grapevine WTP to aid in coagulation.
♦ All coagulating chemicals produced settled water with acceptable turbidity
levels. There were no significant performance differences beiween alum and
fecric sulfate in terms of turbidity removal at the plants.
Ozonation Pilot Testing
♦ At the Grapevine plant, preozonation slighUy improved turbidity removal in
six of eight jars tested over the four quarters. This comparison was made
each quarter behueen samples of the raw, low-ozonated, and high-ozonated
water using the same coagulant dose. [n the other two cases, lower coagulant
doses (than those used with the raw water) produced lower turbidities in the
ozonated water. This suggests that o2onated water may require different
doses of coagulant (from raw water) in order to achieve the same turbidity
removal.
~ Preozonation alone did not improve TOC removal. TOC levels in the
unozonated and ozonated settled water were approximately the same.
However, it is anticipated that the TOC removal at the full-scale ozone plants
will improve because of additional TOC removal in the biological filters.
Ozone condirions water so that biological growth can occur in the filters.
~ Preozonation conholled chlorination byproduct (TTHMs and HAAs)
formation. It is very likely that the City's finished water TTHM and HAA
levels would be below 0.04 and 0.03 mg/L respectively, if preozonaHon
facilities were installed.
~ The threshold odor numbecs (TON) were not reduced significanfly by
preozonaflon. Raw TON numbers were typically low enough at this plant that
it would be difficult to determine the eKect that ozonation would have on
them. ~
~ Bromate levels exceeding the SDWA MCL of 10 Ug/L. were formed by high
ozone doses in two of the four quarters. lt is likely that this could be
controfled by adding ammonia to the raw water upstream of ozonation.

WATER TREATMENT PLANT RENOVATIONS AND EXPANSION
CITY OF BEAUMONT
Freese and Nichols has been involved in the development and expansion of the
BeaumonYs water treatment facilities since the 1920s:
1929 Freese and Nichols designed a filtration plant consisting of chemical
facilities and aerator (for manganese removal), flocculators, two
sedimentation basins and four rapid mix sand filters rated at a capacity
of 4 MGD.
1941 Freese and Nichols was selected for the expansion of the facilities to a
total capacity of 10 MGD and the construcfion of a 5 million gallon
underground cleanuell, which remains in service today as the "South"
cleanvell.
1948 Freese and Nichols designed a new 10 MGD addition to the treatrnent
facilities, which is referred to as the "North" plant and is operated
independently of the South plant.
1959 Further improvements were designed by Freese and Nichols when a
new five million gallon underground cleanuell was conshucted.
1983 Freese and Nichois designed a 16 MGD expansion to the water
heatrnent plan, which upgraded the plant from 10 MGD to 26 MGD.
1999 The City of Beaumont authorized Freese and Nichols to pedonn
Engineering Studies of the City's water supply source, surface water
treatment plant facilities and groundwater production facilities. The
pucpose of the study was to determine the capacity of the water
production facilities and improve them as necessary to provide for the
water needs of the City of Beaumont and its outside customers to the
year 2020.
2000 Freese and Nichols improved the raw and treated water delivery
systems. The firm then designed a 14 MGD expansion to the water

Team to complete this task most efficiently.
REGULATION WORKSHOP
Our team is ready to conduct workshops to the water treatment plant staff if needed
to assist the staff in understanding the current and future regulations that may affect
the water treatrnent. Freese and Nichols' reputafion for understanding the Safe
Drinking Water Act (SDWA) regulations is underscored by the fact that the Fort
Worth Water Departrnent and others have invited Freese and Nichols to present half-
day regulations workshops to water treatrnent personnel from their staff. A
Aegulatory Updote handbook prepared by our staff serves as the backbone to our
training and assistance to clients throughout Texas.
PROJECT MEETINGS AND STATUS UPDATES
Throughout the Water Plant Production Evaluation, the key members of the Team
will meet with the City at different project milestones to hold project workshops and
meetings with the City staff to gamer input from the City and to convey the ongoing
results. These meetings will be held to help foster a high level of communication
between the
Freese and
Nichols Team
and the City
and to facilitate
the City
involvement in
the detailed
evaluation and
planning for
future
improvements.
Freese and
Nichols will
utilize state-of-
the-art
technology, including 3-D renditions and PowerPoint when appropriate, to present
concepts and altematives to the City Council and/or staff.

WATER TREATMENT PLANT ASSESSMENT
The treatrnent plant production evaluation will include an assessment of the different
treatrnent processes including the planYs rapid mix basins, the flocculation /
sedimentation basins, chemical feed addition and disinfection as well as filtration and
treated water storage. In addition, raw and treated water pumping capacities and
sludge production rates and s(udge disposal will also be assessed. Our experience in
evaluation and design of different types of filters (air scour, Aries, underdrains, filter
media etc.) and filter renovations
allows us to present altematives
in a format that facilitates
informed decisions to best meet
the needs of the City. In the past
10 years, our team has designed
more than 50 filters (new or
renovated) to heat over 250
MGD at 12 different water
heatrnent plants in Texas. A
listing of recent filter projects in
included in the Appendix.
We will also assess immediate
and long-tenn requirements for
compliance with various
provisions of the Safe Drinking Water Act and make recommendations for optimizing
the production capacity of the plant. Our strong working relationship with the Texas
Natural Resource Conservation Commission (TNRCC) and other regulatory agencies
coupled with a good understanding of the regulations will help the Ciiy in its efforts
to ensure that it is meeting current and future applicable regulations. Freese and
Nichols has recently completed SDWA Evaluarions for more than 12 water treatrnent
plants in Texas.
CONSTRUCTABILITY & COST EST[MATING
Cost estimating is essential to help make sound decisions for the City. Freese and
Nichols employs a large group of full-time construction professionals dedicated to the
constrvction of water and wastewater treahnent facilities in Texas. These
Inno~c'i~~e AUU n ,ches.. . .
rr.i-ese-rvieNOLs
Water Treatment Plant Produdion Study
professionals, led by Lany Eckersley, will evaluate the constructabiliiy and prepare
cost estimates for any proposed improvements resulflng from this study. Our
experience and up to date knowledge of water treatment costs will help the City in
the evaluation of altematives considered during this project phase and detennine
how to resolve any construction issues that may arise.
PRIORITIZATION & SCHEDULING OF IMPROVEMENTS
The team will prioritize any necessary improvements and provide the City with a
"Master Plan" of scheduled improvements. The prioritization will be based on
meeting cunent and future regulations, capacity requirements and maintenance
requirements as well as costs and availabilities of funds.
PLANT PRODUCTION EVALUATION REPORT -

RELATED FILTER DESIGN AND
RENOVATION PROJECTS IN TEXAS
Freese and Nichols was founded over a
century ago when the City of Fort Worth
found it necessary to filter its public water
supply and hired the firm's founder, John B.
Hawley, to design and supervise conshuction
of its water filhation plant. Since then, the firm
has designed numerous fi(ters and
rehabilitated or upgraded many others. While
design practices and technology have
evolved, filtration remains the heart of the
water treatrnent process, and its design
remains a core part of our water treatrnent
design practice. Freese and Nichols'
experience includes a wide range of sizes and
configurations, various media combinations,
conhol strategies and backwash
arrangements. The table below lists some of
the more recent filter projects completed or in
progress by Freese and Nichols and selected

ABSTRACT:
This paper present5 the experience of the Brovm County Water Improvement District R11
(gC WID) tlvough its p articipation in che Texas Optimization Program The District, lo cated
in Brownwood, Texas has a service population of 36,000, providing treated water to the
communities of Brovmwood, Bangs and the Brookesmith Water Supply Corporation.
In this charter year of the state's optimizarion*~program, the BCWID has achieved the
recognirion criteria as set for the Texas Optimization Program. The District is one of the
first water systems in the state of Texas to be recognized under this program, which is
similaz to the AWWA Parhlership for Safe Water Program.
The purpose ofthe state-implemented program is to maximize the performance of an existing
'treatment plant by addressing the factors which limit iis performance. The goal of the
program is to reduce the risk of waterbome diseues by reducing the number of pathogenic
organisms that could pass through a treatment plant.
Through the optimization of the BC WID treaiment plant's performance, the District realized
a cost savings in chemicals while improving plant performance.
This paper presents a review ofthe optimizarion process from parrncipation in the voluntary
Texas Urility Co-op Program for training 6Y the state of Texas in the Comprehensive
Performance Evaluarion (CPE) approach. This process involves the actual CPE study of
the plant and of the approach to modifying the four major conh-ibuting areas which impact
plant performance (operations, design, adminisiration and maintenance) in ordec to oprimize
treatrnent plant performance to meet the Tesas Oprimization Program's goals.
Teaas Optimization Proeram's Iiecoenition Criteria
i. Filtered Water Turbidity less than or equal to 0.1 NN ia 90% of the readings for
each filter.
2. Filtered Water Turbidity less than or equal to 0.1 NTU in 95% of the readings for
all filters.
3. No Filtered Water Turbidity greater than 0.5 NTIJ• backv✓ash
4. Filtered Water Turbidity less than or equal to 0.3 IVT[J durinB Post-
turbidity spikes.
5. Recovery to less than or equal to 0.1 NTU within 30 minutes.
I. INTRODUCTION
A. Who is the District?
The Brown County. Water Improvement District 91 is a water urility that sells raw and
treated water to various ciees in Brown County, Texas. The primary water source for the
District is Lake Brownwood. WaterispumpedfromLakeBrovmwoodtoaterminalstorage
reservoir on the edge ofthe City ofBrownwood. Water flows by gravity from the terminal
storage reservoir to rivo water treatment plants, the Eut Water Treatment Plant and the
West Water Treatment Plant. The East Plant was constructed in 193 8 and the West Plant
addedin1985. TheEastWaterTreatmentPlantisprimarilyusedonlyduringhighdemand
months. Afterthewateristreated,highservicepumpsfrombothReatmentplantspumpthe i
water to two 1 MG ground storage tanks located on White Mines Mountain. These tanks
act as elevated storage to all customers receiving treated water from the District The
District, located in Brownwood, Texas has a service popularion of 36,000 and provides
treated water to the communities ofBrownwood, Bangs, and the Brookesmith WaterSupply
Corporaeon. Figure 1 depicts the District's locaynon.

B. What is the Texas OptimizaHon Program?
The state of Texaz hu a public water rystems participarion recogudon pro,am. The
program administrated through the Texas Natural Resource Conservarion Commission is
called the Texas Optimization Program or TOPs. This program is completely voluntary
and is a way that the state of Texu can recognize plants that meet very demanding
performance criteria The program formally commenced on July 1, 1997. Plants that
participated in the charter yeaz of the program and achieved the recogrlirion criteria
continuously since July would be eligible to receive the first recogurion awazd in eazly
1998. To date, two faciliries in the state of Texas have been recognized by the Texas
Natural Resource Conservation Commission to have met these requirements. They are
Brown Counry Water Improvement Dish-ict #1 and the City of Greenville, Texas.
The recognition program operates on 18-month cycles. By the end of the first cycle,
participants must achieve three objectives. Specifically, the plant must:
1. Install an on-line turbidity meter on the dischazge line from each filter.
2. Meet the recogution criteria at least three out of every six months.
3. Receive at least one optimization arvazd~i.e., have met the recognition criteria for
at least one consecutive sis month period.
Participants who have not achieved the first objective by the end of the first cycle, will be
required to withdraw from the program until the turbidimeters have been installed.
Participants who have met the first, but not both of the other two objectives, must either
withdraw from the program or agree to have an independent parry conduct a
comprehensive performance evaluation (CPE) at the plant by the end of the 241 month.
Participants who tal:e active steps to address the performance Iimitarions (limiting factors
that were idenrified during the CPE) can remain in the recognition program for a second
18 month cycle. However, participants who do not meet the three objec[ives during the
second 18 month cycle must withdraNv from the recognirion pro,o,ram for at least 12
months.
As soon as the plant meeu the recogrtition criteria for six consecutive months,
participants will be eligible for the oprimization awazd and the 18 month cycle begins
again. Since an award can be eamed each six month, a treatment plant can eam rivo
awazds each yeaz if it meets the performance goals continuously. Figure 2 is a flow
chart that depicts the Texas Oprimization Recognition Program milestones and
requirements.
The Texas Oprimization Program recognition critaria is based on performance of four
treatrnent processes:
1. Sedimentation basins/clarifiers
2. Filters (excluding the post-bac4.-vash recovery period)
3. Filters (post-bact.tivash recovery period)
4. Finished water.
The performance goals for each of these processes is given in Table 1. The Texas
Optimization Program recognition requires the fotlowing turbidity monitoring locations:
1. Raw water entering the plant
2. Settled water at the end of the buin
3. Filtered water at the effluent of each filter
4. Finished water entering or teaving the clearwell. •
The turbidity monitoring frequencies are given in Table 2.

Table l: Turbidity Monitoring Requirements
The Texas Optimizafion Program recognition criteria establishes the following
reporting requirements: For each clarifier/sedimentarion basin
• total number turbidity readings
• number of settled water readings above 2.0 M'il
• percentage of settled water turbidity reading above 2.0 NT[J
• number of settled water readings above 5.0 NTU
• maximum turbidiry level recorded
• minimum turbidity level recorded
For each filter (excluding any data collected during the first 30 minutes following a backwash ~
cycle)
• total number turbidity readings
• number of filtered water readings above 0.1 NN
• percentage of filtered water turbidity readings above 0.1 NTU
• number of filtered water readings above 0.5 NTU
• maximum turbidity level recorded
• muumum turbidity level recorded
For each filter profile:
• date that the special study on post-backwash turbidity profile was iniriated
• maximum turbidity level recorded during the first 30 minutes of filter run
• turbidity level exactty 15 minutes after the filter is retumed to service
• turbidity level exac[ly 30 minutes after the filter is retumed to service
• maximum turbidiry level recorded during the remainder of the filter run
For raw and finished water.
• daily raw water turbidity
• fuushed water turbidity every 4 hours
The program requires at least once each month, a post-backwash turbidiry profile be
conductedoneachfilter. Duringthisprofile,theturbidity data must be collected duringo the
entire filter run usina a on-line turbidimeter with a continuous recorder. For the first 30
minutes of the fil[er run, data must be collected at one minute intervals. After 30 minutes,
the sampling must be conducted at least once every 15 minutes.
The program also recommends the following additional monitoring:
• The pH and alkalinity of raw water entering the plant should be monitored once every
four hours.
•'The pH and alkaluuty of the effluent ofthe rapid mix (or at some other sitejust ahead
of coagulant addition) should be monitored every four hours.
• The pH at a point locatedjust after pH adjushnent (for example, just after lime, soda
ash, or caustic addition) to be monitored every four hours.
The program allows the use ofon-line particle counters or particle monitors iriscead ofon-lina
turbidity meters provided that the participant is able to demonstrate that the particle count
nwnbers for their particulaz plant is equivalent to a turbidity of less than 0.1 NTU. It is srill
required that at least one portable turbidimeter/recorder for monthly filter profiling be
provided. (1) (2) (3)

insighi into projecting future capital and operahng expenditures to meet the new regularions.
The Aistrict also has established a leadership role in the region's water urilities communiry.
The District is considered a technical resource by many of the region's water utiliries and
is often approached by the rewlatory agencies to pioneer newwater progams. None ofthis

A. Facility Design Features
The West W aterTreatment Plant was constructed in 1985 and is rated by theTexas Natural
Resource Conservation Commission as a 10 MGD plant. The facilities consistofaterminal
storage reservoir for pre-settling, a rapid mic unit for chemical miYing, cwo-stage flocculation
with variable speed drive units, sedimentation bazin with tube settlers for enhanced settling,
variable decluung rate filters with air assisted backwash, multiple disinfection zones and
baffled clearwell for enhanced disinfection contact time. Figure 3 shows the facility layout.

There are several unique features relating to the design of this faciliry. Figure 4 depicts
these features. They include the following:
1) Terminal storage rese[vo4 which'provides for not only pre-settling to the treatment
unit, but provides for a more uniform and consistent water quality.
2) The facilities have the capability to retum backwazh water direcdy to the temzinal
storage reservoir. It has been detemuned by the operating staff that by slighdy
overfeeding polymer in the backwash retum line> the temvnal storage resecvoir can
achieve enhanced settling chazacteristics.

3) The flocculators have been equipped with variable speed drive units. Variable speed
drive units were originally installed for plant flexibility and adjusting for changge in water
qualiry conditions. The plant haz also Found that if operarions of the rapid mix unit is
impaired, adequate additional mixing can be achieved by adjustmef Lhe s dathe water
drive and flocculator units. This type of operating flexibility hu greatlY ass
treatment plant operators in maintaining the Texas Optimization criteria on settled water.
4) The sedimentarion basin is equipped with tube settlers for enhanced clarification. The.-
Brown County Water Improvement District #1's plant was one of the first in West Texas
to urilize tube settlers for not only enhanced clarificarion, but for reduction of the state of
Texas required six hour detention rime. With the addirion of the tube settlers, the
sedimentarion basin detention time has been reduced from six hours to two hours,
resulting in a substantial construcrion cost savings while demonstraang excellent
clarificarion capabiliries. The sedimentarion basin also is uniquely designed to allow for
mechanical sludge collection in the fint half of the basin where the majority of solids aze
iniRally deposited.
5) The treatment plant is also one of the first in West Texas to employ decluring rate
filters. There aze two basic methods of operating filters. They diffec primarily in tha Way
that the driving force is applied across the filter. These methods are referred to as
constant rate filtration and variable dectining rate filtration.
In constant rate filtration as constant pressure is supplied across the filter rystem and tha
filtration rate or water leve( is then held constant by the action of a mechanicallY operated
or automatic effluen[ IIow control valve. At the begirming of the filter run, the filter is
clean and has little resistance. If the fiill driving force were applied across the filter, the
flow rate would be very high. To maintain a constant flow rate or water level, some of
the available driving force is dissipated by a effluent control valve.
Variable declining rate filters operate with no individual control rystems except for a flow
limiting device (orifice plate). The T'NRCC allows at the beginning of filter run a
maximum range for declining rate filters, the maximum filiration rate is 6.5 gpm/sf. The
filter dischazge piping is usually designed wich an ori5ce or other permanently installed
flow limiting device to ensure that the maximurn filter rate can not be exceeded.
In variable declining rate filters, each filter will accept the porcion of the total flow
permitted by the common water level above all the filters. The water level above the
filters, or head, provides the driving force for the water through the filter media As
filtrarion continues, the flow through dirtiest filter will decrease more rapidly than tlvough
the other filters, causing the flow to re-distribute itself automatically so that the cleaner
filters pick up the capaciry lost by the dirtier filte{s. The water level rises slighNy and the
re-distribution of flow to provide the additional head needed by cleaner filters to
compensate for the decreased flow through the dirtier filters. The cleanest filter accepts
the greatest flow increase and the redistriburion.
This method of operation causes a gradually declining rate towazd the end of a filter run.
Rate changes throughout the day due to changes in total plant flow, both upward and
downwazd, occur gradually and smootkily without any automatic control equipment. The
declining rate fillrarion rystems main advantage is the savings in valve and piping
arrangements. It is a simpler rystem to operate and allows for greater operating
flexibility. Figure 5 illustrates the variable declining rate filter structure.
6) Air assisted backwash capabilities provided at the filters. There are three tradi[ionally
used backwash methods:
• water only backwazh
• water and surface or sub-surface wash media scour
• water and air scour
~ Pigure 5: Declining Rate Filter Structure
~ ~
Backwashing practice involves the use of high velocity wazh water which is introduced
into the filter bed in the direction opposite to the normal 5ltering flow. The backwash
expands the 51ter beds 20 to 50 percent of the bed's original volume. The sole iue of
backwash has not proven to be a satisfactory rystem for dual media filters which allow a
deeper penetration of solids into the filter bed. 'Ihe deeper solids penetration requires a
more efficient backwash rystem. In order to enhance the backwash capabilities with
dual media, the Brown County Water Improvement Distric[ # 1 Treatrnent Plant has
utilized both air and water backwash. This allows for a lower backwash water rate and
provides for greater adaptation of the filter media t}uough the introduction of air. The air
and water backwash system maintains the filter media in a cleaner condicion.
7) Mulriple disinfec[ion zone. The plant has three principal disinfection zones for
flexibility of operation and oprimizarion of disinfeceon contact values throughout the plant.
Disinfec[ion is currently accomplished by adding pre-chlorine in the water line between
the temlinal storage reservoir and the rapid mi:t basin (Zone i). The free ctilorine is
converted to chloromines in the rapid mix basin by the addition of amrnonia. and continues
through filtraeon (Zone 2). Disinfection is cocrYpleted tkvough the transfer pump station
and clearwell storage which is ba87ed prior to being delivered to the Disri-ict's first
customer (Zone 3). By utilizing mulriple disinfecrion zones, disinfecrion by-products can
be better controlled along with maintaining the proper disinfection residuals and contac[
times throughout the system.
8) Ba$led Cleazwells. The Disfict wu one of the first planu in Texas to add baffling in
its clearwell storage to enhance and improve the disinfecrion contact rime. The c(eanvell
contains five baffles varying in len;th from 40 feet to 60 feet in a circular tank. The
baffles aze made of a vinyl curtain fabric material. The baffling arrangement provided
increased the bafIling ratio in the cleazwell from 20°/a to approximately 80%. The
District can reduce the required free chlorine addition by appro:cimately 50% and the
required chloramine addirion by 20%.

g, CpE IniHal Assessment needs
It is becoming ever more difficult for water rystem operators to assess the planning
for compliance with changing and evolving regudarions in the water industries. Operators of
systems find it difiicult to dedicate the 6 me and resources necessary to stay current with
consistenUyevolvingregulations. TheTexasNaturalResource ConservarionCommission
hu implemented a co-op program which trains oPerators in the EPA comprehensive
performance evaluarion (CPE) assessment techniques for water treahnent planrs.
The comprehensive performance evaluation is an approach developed by the U.S.
Environmental Protection Agency to improve surface water treatrnent plant performance
and help assure cost-effective compliance to the surface watertreatment rules (SWTR).(4)
The approach consists of two steps, comprehensive performance evaluation (CPE) and
comprehensive technical assistance (CTA). A CPE is athorough evaluarion of an existing
treatrnent plant including assessment of the unit treahnent processes capabilities and the
impact ofthe operatior, maintenance and administrative practices on optimal performance
of the plant. CTA is used to oprimize performance of an existing plant by systemarically
addressing factors that limit performance idenrified during the CPE. Therefore, the CPE
approach can be urilized to evaluate the ability of a water filtration plantto meet the turbidiry
and disinfection requirements of the surface water treatment nile and then facilitate
achievement of cost effective compliance. In some cases, a CPE may result in costs-
savingsand/orincreuecapacity. TheCPEusesa,fourstepapproach:l)evaluatemajorunit
processes, 2) conduct performance azsessment, 3) identify limiting factors, and 4) prepare
a report offindings. TheTTIRCC through the co-op voluntary urility program conducted a
CPE at the Brown County Water Improvement Dishict 9 1's plant in October of 1996.(5)
The resulu ofthe inicial CPE are summarized on the following figures. Figure 6 depicts the
raw water narbidity to the plant. Fio re 7 depicts the raw waterturbidity in terms ofpercent
frequency. Figure 8 depicts the settled water turbidity variations for the 12-month period.
Figure 9 depicts the percent fre,quency occurrence for settled water turbidity for the study
yeaz. It should be noted that the oprimization goal of a settled water turbidity of2.0 NNs
was inieally met only 25 percent of the rime. Figmure 10 depicts the finished waterhubidity
and the current regulatory standazd of 0.5 NNs. Figure 11 depicts the finished water
turbidityfrequency occurrence forthe 12-month period and indicates and depicts theTexaz
pptimization goal for individual filters of 0.1 NTUs. It should be noted that the uutial CPE
indicated the plant was achieving t}us goal less than 5 percent of the time.

The CPE idenrified the following performance limiting factors:
• The existing turbidity meters were not accurate at low turbidity readings.
• There waz no policy in effect•at the rime to require changes in operation when tazget
optimizarion goals were exceeded.
.'Ihe alarm point for turbidiries were not set at target oprimization goals. There was no
redundant backwash pump nor rapid mix motor.
This inihal CPE became the baseline for the plant operating staff to establish its Texas
Oprimizarion program goals and could be used to azsess the program's effectiveness. It
should also be noted that the data compiled during the CPE waz bazed upon the existing
rurbidity meters, which were determined to be inaccurate a[ low readings. These meters
were_immediately replaced with more sensirive and accurate turbidity meters on each
filter. I
C. Program Investment
The major program investment was the replacement of outdated turbidity meters with
new more accurate meters. The old meters had reached their useful life and were
scheduled for replacement. The reporting requirements were incorporated into the
normal plant operating duties and had no sigiificant effect on the plant operator's
schedule.
D. Operational Modifications
After the initial CPE assessments, the District embazked on its oprimization program•
The inirial phase waz to assess the chemical addirion. Extensivejar testing was
conducted for several months to establish an "operating matrix" for chemical addition
based on changes in water pH, alkalinity, and temperature..
Thejaz testing program also tested several types of coagulants and polymers and hybrid
combinations of polymers/coagulants. The coagulant type and dosage rated were
changed bazed on the chemical testing program.
'Ihe plant developed an operating procedure which adjusted the variable speed
flocculators based on water chazacteristics and the developed "operating matrix".
Every operating shift had the responsibility and authority to ma}:e the necessary
operational adjustments.
The filters were evaluated on an individual filter basis and a unique dovm ramping rime
for each filtec was developed. Figure 16 gives a typical filter post-bac},-wazh turbidity
profile.
To sumrnarize the operational modifications for the optimization program chey consisted
of:
(1) Chemical additives evaluarion program. N
(2) Development of an "operating mahix" for chemical addition and changing water
quality.
(3) Development of individual filter profiles and operating procedures for each unique
individual filter.
(4) Empowering all operating shifts with the responsibility and authority to make the
necessary operarional adjustments. .
M. FINDINGS
A. Sedimentation Basin Performance
The Texas Optimizarion Program's performance goals for sedimentarion basin
performance is that all of the turbidiry readings from each basin be less than or equal to
2.0 NTUs. This is not a recognirion criteria for the pro,am> but is a reportin,
reqwremenG Plantr must collect turbidity samples at least once each day from the
efiluent of each sedimentation basin. These samples must be collected with the basin in
operation. The plant may collect settled water hubidiry data more frequently than once
each day, i.e., once each'shift or once every four hours. However, the sampling should
occur at the same rate throughout the month and at regular intervals when the basin is
operating. The program monthly operating report allows counting the number of turbidity
readings above 2.0 NTU and the number above 5.0 NTU rounded to ihe nearest 0.1
NTUs, and allows for rounding of the percentage above 2.0 NTU to the neazest 0.1
percent The monthly operating repoR also requires reporting ofmaximumNNs and
miniinum NNs for settled water. (4) Figure 12 presents a graphical plot of the settled
water turbidity during the recogution period and Figure 13 depicts the percent frequency
of occurrence of NTU values.
As depicted from the graphs, the plant maintained about 80 percent of the performance
goal limit of 2.0 NT[Js.

B. Filters Without Post - Baclcwash Performance
The Texas Oprimization Program requires that planis must collect turbidity samples at .
least once every four hours from the effiuent of each filter. The plant may collect the
filtered water turbidity data more frequendy than once every four hours, i.e. once an hour
or once every 15 minutes. However, the samples must occur at the same rate throughout
the month and at regilaz intervals. Only the data collected when the filter is on line and
dischaz;ing to the clearwell is to be used. The program does not permit data collection
when the filter is idle or when the filter operation is in the backwash mode. When
counting number of the turbidity readings above 0.1 NTU and a numbec above 0.5 NTUs,
the turbidity readings can be rounded to the nearest 0.1 NTU. Therefore, a reading of
0.14 NTiJ would be reported as a 0.1 NTU reading. The repordng forms require that the
maximum and mirumum turbidity readings be rounded to the neazest 0.01 NTU and that
the perceniage above 0.1 NTiJ can be rounded to the neazest 0.1 percent (4) Figures 14
and 15 depict the filtered water turbidity and the percent frequency occurrence,
respecrively.

C. Filter with Post-Backwash Performance
The program requires that plants generate a filter run profile for each filter at least once
each month, using a continuous online turbidity meter. The plant must record the data
using a strip char~ circulaz chart, or computer or other device capable of producing a
hard copy of the results. Data collected during the first 30 minutes of the filter run must
be recorded at one minute intervals and data collected during the rest of the run must be

IV. SUMIYIARX
A. Comparison of Plant Performance from Initia] Comprehensive Performance
Evaluation to the Teaas Optimization Program Goals Achieved
Utilizing the inirial comprehensive performance evaluation u a baseline for performance,
comparison and evaluauon, Figure 19 illustrates the settled water turbidity frequency plot.
Settled water turbidity has been improved from meeting a 2.0 NN less than 25 percent
of the time, to meeting a 2.0 NTU 99.9 percent of the time. Figure 20 illustrates the
bottom line resulu for finished water turbidiry frequency plot. The plant performance
increased from achieving a 0.1 NN appro;cimately less than 5 percent of the time to
achieve a 0.1 NN over 100 percent of the rime.

B. Benefits to the District and its Customers
The Texas Optimizarion Program demonstrated that the Brown County Water
Improvement District 4 1 Water Treatment Plant will be able to comply with the proposed
microbial-disinfectants/disinfection by-products (M-DBP) and interim enhanced surface
water treatment nile proposals which are anticipated to be promulgated in November of
this yeaz. The optimization program also had several other side benefits, including raising
the public confidence and awazeness of the public water supply and recognirion of the
plant's operabng staff's excellent capabilities. Monetary benefits were derived from
chemical oprimizarion and less plant down rime due to pre-planning and closer attention to
process controls.
C. Brown County Waterlmprovement District 91 Receives Top Award for
Drinking Water Quality
The Texas Natural Resource Conservation Commission (TNRCC) honored the Brovm
County Water Improvement District #1 on May 13, 1998, with a state awazd under this
new program recosnizing outstanding drinkingl+'ater quality. Although the District
already met regulatory standards at its drinl:ing water treatment plant in 1996, the District
iniriated a voluntary review of its facility. The evaluators from the Texas Engineering
Extension Service and Texas Co-Op Utility Program conducted a comprehensive
perFormance evaluarion of the treatment facility. The District entered the Texas
pptimization Program and achieved significant improvements in drinking water quality.
As a result the turbidity of the water currently leaving the treahnent facility is more than
five rimes lower than current state requirements. The treatment plant has demonstrated
that it will be able to meet the pending more stringent regulations.
D. Partnership for Safe Water Program
The American Water Works Association (AWWA)/IJS Environmental Protection
Agency (EPA) Partnership for Safe Water Program consists of the following steps:
Phase 1:
Sigrt Up
Phase 2:
Data Submission (one yeaz turbidity date)
Phase 3:
Self-Assessment and Correction
Phase 4:
Third-Party Assessment and Correction
The major difference beriveen the partnership for Safe Water Program and the Texas
Oprimizarion Program is the requirement for ihe Phase 4 third-parry assessment and
correction.
It is likely that Texas plants which participate in the voluntary Texas En;ineering
Extension Services (TEEX) comprehensive performance evaluation (CPE) program vnll
satisfy the Phase 4 requirements for a third-party assessment.
