Optimization and Treatability Laboratory
Freese and Nichols is one of a very few consulting firms that maintains an
in-house water treabnent optimization laboratory for conducting chemical
and settling tests. We also own and operate a portable ozone pilot-testing
unit. This capability allows Freese and Nichols to have the analytical
equipment to accurately access and predict specific plant performance
objectives from chemical optimization through the newest technology
innovations.
.
We have been very successful at assisting our clients in meeting
alternative compliance strategies and optimizing plant production. For
example, we have assisted clients in obtaining higher plant capacity
ratings, based on demonstrated operating performance, while achieving
the more stringent regulatory requirements without or at a very minimal
capital invesbnent.
We look forward to working with the City of Paris on this important assignment.
If you should have any questions regarding the attached proposal. please advise

is very pleased to respond to the:
REQUEST FOR PROPOSALS FOR A PRODUCTION STUDY OF THE
WATER TREATMENT PLANT OF THE CllY OF PARIS, PARIS, TEXAS.
Freese and Nichols, Inc.
The Federal 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 to respond to
new and emerging threats to safe drinking water. In 1993, a Crytosporidium
outbreak in Milwaukee caused:
illness
400,000 people to experience intestinal
~
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 between microbial pathogens (Interim Enhanced Surface
Water Treatment Rule-IESwrR) 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 SDW A has promulgated various drinking water regulations which require
simultaneous compliance. Some of these competing regulations directly 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

Beginning January 1, 2002, all surface water treatment 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 Treatment Rule (LT2ESwrR). These rules
will require more thorough monitoring and treatment.
Treatment plants should consider a variety of compliance options. Including capacity
reduction, or seasonal capacity reduction to meet more stringent requirements,
optimization of treatment, alternative compliance criteria, exceptions, chemical and
physical modification, and operational changes.

Following World War I. Major Hawley returned to Fort Worth and resumed
his engineering practice in 1919. One of his first notable postwar projects 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 COUNIY WATER IMPROVEMENT DISTRICT
Freese and Nichols first designed the Brown County WID water treatment plant in
1986. The innovative treatment process used at Brown County WID's 10 MGD
treatment plant employs tube settlers in the clarification 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 followed by filtration in dual media gravity filters with air/water
backwash. Operations are simplified by splitting influent flow evenly between 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
seIVices.
Currently, Freese and Nichols contracted to conduct an uprating evaluation for the
water treatment 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.
....
~PSU
On Wednesday, Moy 13, 1998 the
District was honored by the TNRCC and
received recognition os one of the first of
only two water treatment facilities in the
state to achieve the high quality
standards under the Water Optimization
Program. The quality of water being
produced equates to five times better
than normal standards. The District's
board General Manager, Harry Miller,
Assistant General Manager, Sam
Oswood ond treatment stoff were singled
out for their efforts in providing the
highest quality water for Brown County.
The District received this prestigious
award for the second time on October
14, 1998, making it the only water
district in the state to hove received the
award twice.

SAFE DRINKING WATER ACT IMPLEMENTATION
GREENBELT MUNICIPAL & INDUSTRIAL WATER AUTHORIlY
Freese and Nichols. Inc was authorized by the GMIWA to assist the Authority in
conducting a plant evaluation to meet the Stage 1 Disinfection Byproduct Rule (Stage
1 DBPR) and Interim Enhanced Surface Water Treatment Rule (IESWfR). The
Stage 1 DBPR and IESwrR were promulgated on December 16,1998 and the
compliance date for both regulations is set for the GMIWA on January 01, 2002. The
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 IESWfR. The Stage! DBPR lowers the
existing total trihalomethanes (TIHMs) limit and set a new limit for haloacetic acids
(HAAs). In addition, depending on raw water quality, 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
treatment process, coagulation using ferric sulfate and alum. Promulgated Stage!
DBPR would likely require the GMIWA 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
percentages of TOC removal and reduce disinfection byproducts such as TIHMs
and HAAs.
The purpose of this report was to present the results of the enhanced coagulation jar
testing performed from Winter 1999 to Fall 2000, and to develop a compliance plan
with respect to the TOC removal requirements, turbidity removal requirements, and
TIHMs and HAAs limits of the Stage 1 DBPR.

The STEP 1 TOC removal requirement could be obtained throughout the year with
varying alum and ferric sulfate doses. The STEP 2 TOC removal requirement and
the corresponding doses of alum and ferric sulfate were not obtained because the
PO DR criteria could not be determined. The slopes of TOC versus coagulant doses
were always below -0.03. That indicates the raw water TOC is not amenable to
coagulation.

The raw water SUVA number was below 2 Umg-m in every quarter, which indicates
that raw water TOe is mostly non-humic (not amenable to coagulation) in nature.
These results are consistent with the jar test results, which show that the raw water
TOe is not amenable to coagulation. The GMIW A WTP met the specified TOe
removal in every quarter by meeting the raw water SUVA exception criteria.

The TIHM and HAAS concentrations in the raw water, and in the Simulated

(free chlorine as a disinfectant in the treabnent plant and in the distribution system)
results in TIHM and HAAS concentrations in excess of those allowed by the Stage 1
DisinfectionlDisinfectant Byproduct Rule. The Simulated Distribution System testing
also indicated that these concentrations can be lowered to acceptable levels by using
chloramines for disinfection in the distribution system.

SAFE DRINKING WATER ACT COMPLIANCE
CIlY OF LONGVIEW
Freese and Nichols, Inc. was authorized by the City of Longview to conduct
treabnent plant evaluations for the Sabine Water Treabnent Plant (16 MGD) and the
Cherokee Water Treabnent Plant (27 MGD) in order to meet the newly promulgated
Stage 1 Disinfection Byproduct Rule (Stage 1 DBPR) and Interim Enhanced Surface
Water Treabnent Rule (IESwrR); especially the TOC removal requirement of the
DBPR. The Stage 1 DBPR and IESwrR were promulgated on December 16, 1998
and the compliance date for the City of Longview for both regulations is January 01,
2002. The IESwrR 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 IESWfR. The Stage 1 DBPR
lowers the existing total trihalomethanes (TIHM) 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.
A principal area investigated with respect to TOC removal was the basic chemica
treabnent process, coagulation using alum, Polymer Blend "A" and Polymer Blend
"B". The two polymer chemicals are made by a single manufacturer. Promulgated
Stage 1 DBPR would require the City of Longview to operate both water plants in
"Enhanced Coagulation" mode, increasing the cost of operation and possibly
making turbidity removal more difficult. The purpose of enhanced coagulation is to
achieve higher percentages of TOC removal and reduce disinfection byproducts such
as TIHMs and HAAs.

Color removal by preozonation alone was significantly 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 (TIHMs and HAAs)
formation. It is very likely that the City's finished water TIHM 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 grassy/slightly 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 formed

WATER TREATMENT PLANT EXPANSION
CIlY OF GRAPEVINE
The Grapevine Water Treabnent Plant currently provides water to approximately
18,000 city residents. An expansion completed in 1990 enables the plant to treat up
to 8.0 MGD,

-~:::::::=-~~~~.::'y2.~;.~~~::=~
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 capacity to 8.0 MGD. The existing facilities were
also refurbished to improve the overall appearance of the plant. Freese and Nichols
designed the original plant and subsequent expansions.
Freese and Nichols, Inc. (FNI) was authorized by the City of Grapevine to conduct
treabnent plant evaluations for meeting the newly promulgated Stage 1 Disinfection
Byproduct Rule (Stage 1 DBPR) and Interim Enhanced Surface Water Treabnent
Rule (IESWTR), especially the Total Organic Carbon (TOC) removal requirement of

SUMMARY OF TESTING RESULTS
Enhanced Coagulation Testing
. The STEP 1 TOC removal requirement was 35% for all 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 curve.
. Of the eight exception criteria, only the raw water SUVA exception was met
in the first two quarters at the Grapevine wrP. Otherwise. 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
mgIL to 95 mgIL of alum. In the first two quarters. Alum was unable to meet
either the STEP 1 or the STEP 2 removal requirements. A high dose (95
mgIL) of ferric sulfate met the STEP 1 removal requirement in the first
quarter, and a ferric sulfate dose of 38 mgIL met the STEP 2 removal

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

ferric sulfate in terms of turbidity removal at the plants.

Ozonation Pilot Testing
. At the Grapevine plant, preozonation slightly improved turbidity removal in
six of eight jars tested over the four quarters. This comparison was made
each quarter between samples of the raw, low-ozonated, and high-ozonated
water using the same coagulant dose. In the other tWo cases, lower coagulant
doses (than those used with the raw water) produced lower turbidities in the
ozonated water. This suggests that ozonated 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 conditions water so that biological growth can occur in the filters.
. Preozonation controlled chlorination byproduct (lTHMs and HAAs)
formation. It is very likely that the City's finished water lTHM and HM
levels would be below 0.04 and 0.03 mg/L respectively, if preozonation
facilities were installed.
. The thr~shold odor numbers (TON) were not reduced significantly by
preozonation. Raw TON numbers were typically low enough at this plant that
it would be difficult to determine the effect that ozonation would have on
them.
. Bromate levels exceeding the SDWA MCL of 10 Dg/L were formed by high
ozone doses in two of the four quarters. It is likely that this could be
controlled by adding ammonia to the raw water upstream of ozonation

WATER TREATMENT PLANT RENOVATIONS AND EXPANSION
and expansion of the
CIlY OF BEAUMONT
Freese and Nichols has been involved in the development
Beaumont's water treatment facilities since the 1920s:
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.
1929
a
Freese and Nichols was selected for the expansion of the facilities to
total capacity of 10 MGD and the consbuction of a 5 million gallon
underground clearwell, which remains in service today as the "South'
clearwell.
1941
Freese and Nichols designed a new 10 MGD addition to the treatment
facilities, which is referred to as the "North" plant and is operated
independently of the South plant.
1948
Further improvements were designed by Freese and Nichols when a
new five million gallon underground clearwell was consbucted.
1959
Freese and Nichols designed a 16 MGD expansion to the water
treatment plan, which upgraded the plant from 10 MGD to 26 MGD
1983
The City of Beaumont authorized Freese and Nichols to perform
Engineering Studies of the City's water supply source, surface water
treatment plant facilities and groundwater production facilities. The
purpose 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.
1999
Freese and Nichols improved the raw and treated water delivery
systems. The firm then designed a 14 MGD expansion to the water

WATER TREATMENT PLANT EXPANSION DESIGN
CIlY OF CLEBURNE
Freese and Nichols designed a
5.0 mgd expansion to the
Cleburne Water Treatment
Plant. The design consists of
adding a third treatment train,
which included a flocculation
basin, sedimentation basin and
two new filters. The design also
included a new dual train rapid
mix basin with splitter box
designed for the total plant flow.
,...........
A high service pump station was added along with
modifications to the existing high service and raw water pump
stations. Modifications to the filters were made to incorporate
air scour backwash capabilities. New chemical feed facilities
were added to include lime storage and feed; and storage
facilities for ferric sulfate, PAC and polymer. Electrical design
included a standby generator, which will operate to reduce
electrical peak demands.
Freese and Nichols' Safe Drinking Water Act evaluation
allowed the City to obtain a doubling of plant rating by
"demonstrated performance." The plant will also meet
alternative compliance criteria and will not be subject to TOC
removal requirements.
Construction Completion: May 2002.

WATER TREATMENf PLANT ASSESSMENT
The treatment plant production evaluation will include an assessment of the different
treatment processes including the plant's 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 sludge 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 alternatives
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 treat over 250
MGD at 12 different water
treatment plants in Texas. A
listing of recent filter projects in
included in the Appendix..

We will also assess immediate
and long-term 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 City in its efforts
to ensure that it is meeting current and future applicable regulations. Freese and
Nichols has recently completed SDWA Evaluations for more than 12 water treatment
plants in Texas.
CONSTRUCTABILIlY & COST ESTIMATING
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
construction of water and wastewater treatment facilities in Texas. These

ABSTRACT:
This paper presents the experience of the Brown Co'tUlty Water Improvement District #1
(BCWID) through its participation in the Texas Optimization Program The District, located
in Brownwood, Texas has a service population of36,000, providing treated water to the
communities of Brown wood, Bangs and the Brookesmith Water Supply Corporation.
In this charter year of the state's optimizatio~'program, the BCWID has ~chieved the
recognition 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
similar to the A WW A Partnership for Safe Water Program.
The purpose of the state-implemented program is to maximize the performance of an existing
treatment plant by addressing the factors which limit its performance. The goal of the
program is to reduce the risk of waterborne diseases by reducing the number of pathogenic l
organisms that could pass through a treatment plant.
Through the optimization of the BCWID treatment plant's performance, the District realized
a cost savings in chemicals while improving plant performance.
This paper presents areview of the optimization process from participation in the voluntary
Texas Utility Co-op Progi~ for training by the state of Texas in the Comprehensive
Performance Evaluation (CPE) approach. This process involves the actual CPE study of
the plant and of the approach to modifying the four major contributing areas wl}ich impact
plant performance (operations, design, administration and maintenance) in order to optimize
treatment plant performance to meet the Texas Optimization Program's goals.
Texas Optimization Program's Recognition Criteria
1. Filtered Water Turbidity less than or equal to 0.1 NTU in 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 NTU.
4. Filtered Water Turbidity less than or equal to 0.3 NTU during post-backwash
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 # 1 is a water utility that sells raw and
treated water to various cities in Brown County, Texas. The primary water source for the
District is Lake Brownwood. Water is pumped from Lake Brownwood to a terminal storage
reservoir on the edge of the City of Brown wood. Water flows by gravity from the terminal
storage reservoir to two water treatment plants, the East Water Treatment Plant and the
West Water Treatment Plant. The East Plant was constructed in 1938 and the West Plant
added in 1985. The East Water Treatment Plant is primarily used only during high demand
months. After the water is treated, high service pumps from both treatment plants pump the .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 population of 36,000 and provides
treated water to the communities of Brown wood, Bangs, and the Brookesmith Water Supply
Corporation. Figure 1 depicts the District's location. ..

B. What is the Texas Optimization Program?
The state of Texas has a public water systems participation recognition program. The
program administrated through the Texas Natural Resource Conservation Commission is
called the Texas Optimization Program or TOPs. This program is completely voluntary
and is a way that the state of Texas can recognize plants that meet very demanding
pexformance criteria The program formally commenced on July 1, 1997. Plants that
participa~e~ ~ the charter year of the program and achieved the recognition criteria
continuously' since July would be eligible to receive the first recognition award in early
1998. To date, two facilities in the state of Texas have been rec.ogrUzed by the Texas
Natural Resource Conservation Commission to have met these requirements. They are
Brown County Water Improvement District # 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 discharge line from each filter.
2. Meet the recognition criteria at least three.out of every six months.
3. Receive at least one optimization awarrl;.i.e., have met the recogniti~n criteria for
at least one consecutive six 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 Wltil 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 party conduct a
comprehensive pexformance evaluation CCPE) at the plant by the end of the 24th month. l
Participants who take active steps to address the pexformance limitations (limiting factors
that were identified during the CPE) can remain in the recognition program for a second
18 month cycle. However, participants who do not meet the three objectives during the
second 18 month cycle must withdraw from the recognition program for at least 12
months.
l'
As soon as the plant meets the recognition criteria for six consecutive months,
participants will be eligible for the optimization award and the 18 month cycle begins
again. Since an award can be eamed each six month, a treatment plant can ep.rn two
awards each year if it meets the performance goals continuously. Figure 2 is a flow
chart that depicts the Texas Optimization Recognition Program milestones and
requirements.
The Texas Optimization Program recognition criteria is based on performance of four
treatment processes:
1. Sedimentation basins/clarifiers
2. Filters (excluding the post-backwash recovery period)
3. Filters (post-bad.-wash 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 following turbidity monitoring locations:
1. Raw water entering the plant
2. Settled water at the end of the basin
3. Filtered water at the effluent of each filter
4. Finished water entering or leaving the clearwell.
..;.
The turbidity monitoring frequencies are given in Table 2.

The Texas Optimization Program recognition criteria establishes the following
reporting requirements:
For each clarifier/sedimentation basin
. total number turbidity readings
. number ofsettIed water readings above 2.0 NTU
. percentage of settled water turbidity reading above 2.0 NTU
. number. of settled water readings above 5.0 NTU
. maximum turbidity level recorded
. mini~U?1 turbidity level recorded
For each filter (excluding any data collected during the first 30 minutes following a backwash j
cycle)
. total number turbidity readings
. number of filtered water readings above 0.1 NTU
. percentage of filtered water turbidity readings above 0.1 NTU
. number of filtered water readings above 0.5 NTU
. maximum turbidity level recorded .,
. minimum turbidity level recorded
For each filter profile:
. date that the special'study on post-backwash turbidity profile was initiated
. maximum turbidity level recorded during the first 30 minutes of filter run
. turbidity level exactly 15 minutes after the filter is returned to service
. turbidity level exactly 30 minutes after the filter is returned to service
. maximum turbidity level recorded during the remainder of the filter run
l
For raw and finished water:
. daily raw water turbidity
. finished water turbidity every 4 hours
The program requires at least once each month, a post-backwash turbidity profile be
conducted on each filter. During this profile, the turbidity data must be collected during the
entire filter run using a on-line turbidimeter with a continuous recorder. For the first 30
minutes of the filter run, data must be collected at one minute intervals. After ~O 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 alkalinltY of the effluent of the rapid mix (or at some other site just ahead
of coagulant addition) should be monitored every four hours.
. The pH at a point located just after pH adjustment (for example, jtist after lime, soda
ash, or caustic addition) to be monitored every four hours.
The program allows the use of on-line particle counters or particle monitors instead of on-line
turbidity meters provided that the participant is able to demonstrate that the particle count
numbers for their particular plant is equivalent to a turbidity ofless than 0.1 NTU. It is still
required that at least one portable turbidimeter/recorder for monthly filter profiling be
provided. (1) (2) (3)
C. Why did the District Participate in the Program?
The Texas Optimization Program is completely voluntary. The District saw the program as
an opportunity to assess the treatment plant's capability to meet the proposed more stringent
enhanced surface w.ater treatment rule and disinfection by-products regulations. The goal
of the program is to reduce the risk of waterborn diseases such as Cryptosporidium and
Giardia. The District felt that by taking this pro-active stance that it would gain valuable
insight into projecting future capital and operating expenditures to meet the new regulations.
The District also has established a leadership role in the region's water utilities community.
The District is considered a technical resource by many of the region's water utilities and
is often approached by the regulatory agencies to pioneer new water programs. None of this
activity would be possible without the foresight and support of the District's Board of;
Directors and administrative staff The District's recognition of the benefits for pro-active'
planning is an essential part to any successful program or utility operation. As a last, yet very
significant, point is the plant's operating staffs desire to achieve the very challenging and
demanding performance criteria from the Texas Optimization Program. Without the
commitment and support of the Board of Directors, the administrative manage~~nt, the plant
operating staff, and regional water utility supporttbis program would not have been possible.
II. BACKGROUND
A. Facility Design Features
The West Water Treatment Plant was constructed in 1985 and is rated by the Texas Natural
Resource Conservation Commission as a 10 MGD plant. The facilities consist ofa terminal
storage reservoir for pre-settling, a rapid mix unit for chemical mi'ring, tWo-stage flocculation ~
with variable speed drive units, sedimentation basin with tube settlers for enhanced settling,
variable declining 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 facility. Figure 4 depicts
these features. They include the following:
1) Tenninal storage reservoir which' provides for not only pre-settling to the treatment
unit, but provides for a more Wlifonn and consistent water quality.
2) The facilities' have the capability to return backwash water directly to the terminal
storage reservoir. It has been determined by the operating staffthathy slightly
overfeeding polymer in. the backwash return line, the tenninal storage reservoir can
achieve enhanced settling characteristics.

3) The flocculators have been equipped with variable speed drive units. Variable speed
drive units were originally installed for plant flexibility and adjusting for change in water
quality conditions. The plant has also found that if operations .of the rapid mix unit is
impaired, adequate additional mixing can be achieved by adjustment of the variable speed
drive and flocculator units. This type of operating flexibility has greatly assisted the~water
treatment plant operators in maintaining the Texas Optimization criteria on settled water.

4) The sedimentation bas'in 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 utilize tube settlers for not only enhanced clarification, but for reduction of the state of
Texas required six hour detention time. With the addition of the tube settlers, the
sedimentation basin detention time has been reduced from six hours to two hours,
resulting in a substantial construction cost savings while demonstrating excellent
clarification capabilities. The sedimentation basin also is uniquely designed to allow for
mechanical sludge collection in the first half of the basin where the majority of solids are
initially deposited.
5) The treatment plant is also one of the first in West Texas to employ declining rate
filters. There are two basic methods of operating filters. They differ primarily in the way
that the driving force is applied across the filter. These methods are referred to as
constant rate filtration and variable declining rate filtration.
In constant rate filtration as constant pressure is supplied across the filter system and the
filtration rate or water level is then held constant by the action of a mec~anically operated
or automatic effluent flow control valve. At the beginning of the filter run, the filter is
clean and has little resistance. If the full 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 systems except for a flow
limiting device (orifice plate). The TNRCC allows at the beginning of filter run a
maxirn~ range for declining rate filters, the maximum filtration rate is 6.5 gpm/sf. The
filter discharge piping is usually designed with an orifice or other permanently installed
flow limiting device to ensure that the ma...wnurn filter rate can not be exceeded.
In variable declining rate filters, each filter will accept the portion 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
filtration continues, the flow through dirtiest filter will decrease more rapidly than through
the other filters, causing the flow to re-distribute itself automatically so that #1e cleaner
filters pick up the capacity .lost by the, dirtier filte{s. The water level rises slightly 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 redistribution.
TIlls method of operation causes a gradually declining rate toward the end of a filter" run.
Rate changes throughout the day due to changes in total plant flow, both upward and
downward, occur gradually and smoothly without any automatic control equipment. The ..
declining rate filtration systems main advantage is the savings in valve and piping
arrangements. It is a simpler system 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 traditionally
used backwash methods:
. water only backwash
· water and surface or sub-surface wash media scour
· water and air scour

-. .
Backwashing practice involves the use of high velocity wash water which is introduced
into the filter bed in the direction opposite to the normal filtering flow. The backwash
expands the filter beds 20 to 50 percent of the bed's original volwne. The sole use of
backwash has not proven to be a satisfactory system for dual media filters' which allow a
deeper penetration of solids into the filter bed. The deeper solids penetration requires a
more efficient backwash system. In order to enhance the backwash capabilities with
dual media, the Brown County Water Improvement District #1 Treatment Plant has
utilized both 'air and water backwash. TIlls i1lows for a lower backwash water rate and
provides for greater adaptation of the filter media through the introduction of air. The air
and water backwash system maintains the filter media in a cleaner condition.
7) Multiple disinfection zone. The plant has three principal disinfection zones for
flexibility of operation and optimization of disinfection contact values throughout the plant.
Disinfection is currently accomplished by adding pre-chlorine in the water line between
the terminal storage reservoir and the rapid mix basin (Zone 1). The free chlorine is
converted to chloromines in the rapid mix. basin by the addition of ammonia..and continues
through filtration (Zone 2). Disinfection is coritpleted through the transfer pwnp station
and clearwell storage which is baffled prior to being delivered to the District's first
customer (Zone 3). By utilizing multiple disinfection zones, disinfection by-products can
be better controlled along with maintaining the proper disinfection residuals and contact
times throughout the system.
8) Baffled Clearwells. The District was one of the first plants in Texas to add baffling in
its c1earwell storage to enhance and improve the disinfection contact time. The clearwell ..
contains five baffles varying in length from 40 feet to 60 feet in a circular tank. The
baffles are made of a vinyl curtain fabric material. The baffling arrangement provided
increased the baffling ratio in the clearwell from 20% to approximately 80%. The
District can reduce the required free chlorine addition by approximately 50% and the
required chloramine addition by 20%.

B. CPE Initial Assessment
It is becoming ever more difficult for water system operators to assess the planning needs
for compliance with changing and evolving regulations in the water industries. Operators of
systems find it difficult to dedicate the time and resources necessary to .stay current with
. .
consistently evolving regulations. The Texas Natural Resource Conservation Commission
has implemented a co-op program which trains operators in the EP A comprehensive
performance evaluation CCPE) assessment techniques for water treatment plants.
The comprehensive performance evaluation is an approach developed by the U.S.
Envirorunental Protection Agency to improve surface water treatment plant performance
and help assure cost-effective compliance to the surface water treatment rules (SWTR). (4)
The approach consists of two steps, comprehensive performance evaluation CCPE) and
comprehensive'technical assistance (CT A). A CPE is a thorough evaluation of an existing
treatment plant including assessment of the unit treatment processes capabilities and the
impac~ of the operation, maintenance and administrative practices on optimal performance i
of the plant. CT A is used to op~mize performance of an existing plant by systematically .
addressing factors that limit performance identified during the CPE. Therefore, the CPE
approach can be utilized to evaluate the abili ty of a water fil tration plant to meet the turbidity
and disinfection requirements of the surface water treatment rule and then facilitate
achievement of cost effective compliance. In some cases, a CPE may result in costs-
savings and/or increase capacity. The CPE uses a{our step approach: 1) evaluate major unit
processes, 2) conduct performance assessment, 3) identify limiting factors, and 4) prepare
a report offindings. The TNRCC through the co-op voluntary utility program conducted a
CPE at the Brown County Water Improvement District #1's plant in October of1996.(5)
The results of the initial CPE are summarized on the following figures. Figure 6 depicts the
raw water turbidity to the plant. Figure 7 depicts the raw water turbidity in terms of percent
frequency. Figure 8 depicts the settled water turbidity variations for the I2-month period.
Figure 9 depicts the percent fre,quency occurrence for settled water turbidity for the study ~
year. It should be noted that the optimization goal of a settled water turbidity of2.0 NTUs
was initially met only 25 percent of the time. Figure 10 depicts the finished water turbidity
and the current regulatory standard of 0.5 NTUs. Figure 11 depicts the finished water
turbidity frequency occurrence for the 12-month period and indicates and depicts the Texas
Optimization goal for individual filters of 0.1 NTUs. It should ~e noted that the initial CPE
indicated the plant was achieving this goal less than 5 percent of the time.

The CPE identified the follo\ving performance limiting factors:
. The existing turbidity meters were not accurate at low turbidity readings.
· There was no policy in effect 'at the time to require changes in operation when target )
optimization goals were exceeded.
· The alarm point for turbidities were not set at target optimization goals. There was no
redundant backwash pump nor rapid mix motor.
This initial CPE became the baseline for the plant operating staff to establish its Texas
Optimization program goals and could be used to assess the program's effectiveness. It
should also be noted that the data compiled during the CPE was based upon the existing
turbidity meters, which were determined to be inaccurate at low readings. These meters
were immediately replaced with more sensitive and accurate turbidity meters 09 each
filter. .
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 significant effect on the plant operator's
schedule.
D. Operational Modifications
After. the initial CPE assessments, the District embarked on its optimization program.
The initial phase was to assess the chemical addition. Extensive jar testing was
conducted for several months to establish an "operating matrix" for chemical addition
based on changes in water pH, alkalinity, and temperature..
The jar testing program also tested several types of coagulants and polymers and hybrid
combinations of polymers/coagulants. The coagulant type and dosage rated were
changed based on the chemical testing program.
The plant develope~ an operating procedure which adjusted the variable speed
flocculators based on water characteristics and the developed "operating matrix".
Every operating shift had the responsibility and authority to make the necessary
operational adjustments.
The filters were evaluated on an individual filter basis and a unique down ramping time
for each filter was developed. Figure 16 gives a typical filter post-backwash turbidity
profile.
To swnrnarize the operational modifications for the optimization program they consisted
of:
(1) Chemical additives evaluation program. .,
(2) Development of an "operating matrix" 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 operational adjustments.

In. FINDINGS
A. Sedimentation Basin Perfonnance
The Texas Optimization Program's performance goals for sedimentation basin
performance is that all of the turbidity readings from each basin be less than or equal to
2.0 NTUs. This is not a recognition criteria for the program, but is a reporting
requirement Plants must collect turbidity samples at least once each day from the
effluent of each sedimentation basin. These samples must be collected with the basin in
operation. The plant may collect settled water turbidity data more frequently ~an 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 nwnber above 5.0 NTU rounded to the nearest 0.1
NTUs, and allows for rounding of the percentage above 2.0 NTU to the nearest 0.1
percent The monthly operating report also requires reporting of maximum NTUs and
minimWTI NTUs for settled water. (4) Figure 12 presents a graphical plot of the settled
water turbidity during the recognition period and Figure 13 depicts the percent frequency
of occurrence ofNTU values.
As depicted from the graphs, the plant maintained about 80 percent of the performance
goal limit of2.0 NTUs.

B. Filters Without Post - Backwash Performance
The Texas Optimization Program requires that plants must collect turbidity samples at
least once every four hours from the effluent of each filter. The plant may collect the
filtered water turbidity data more frequently 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 regular intervals. Only the data collected when the filter is on line and
discharging to the clearwell is to be used. The program does not pennit data collection
when the filter is idle or when the filter operation is in the backwash mode. When
counting nwnber of the turbidity readings above 0.1 NTU and a nwnber above 0.5 NTUs,
the turbidity readings can be rounded to the nearest 0.1 NTU. Therefore, a reading of
0.14 NTU would be reported as a 0.1 NTU reading. The reporting forms require that the
maximWTI and minimwn turbidity readings be rounded to the nearest 0.01 NTU and that
the percentage above 0.1 NTU can be rounded to the nearest 0.1 percent (4) Figures 14
and 15 depict the filtered water turbidity and the percent frequency occurrence,
respectively.

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 chart, circular 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 dwing the rest of the run must be
collected in intervals at I5-minute intervals. Plants may decrease the sampling intervals,
i.e., increase the sampling frequency. The turbidity readings can be rounded to the
nearest 0.01 NTU. The filter profile must depict the maximum spike after backwash for
each filter showing the maximum turbidity level recorded during the first 30 minutes of
filter operation. For each filter, the turbidity level is recorded every 15 minutes after the
filter is returned to service following a backwash cycle. The turbidity levels recorded
exactly 30 minutes after the filter is returned to service are also reported. (4) Figure 16
shows a typical filter profile graph. It should be noted that the backwash spike did not
exceed the 0.3 NfU post-backwash turbidity spike criteria

IV. SUM1\'lAR Y
A. Comparison of Plant Performance from Initial Comprehensive Performance
Evaluation to the Texas Optimization Program Goals Achieved
Utilizing the initial comprehensive performance evaluation as a baseline for performance,
comparison and evaluation, Figure 19 illustrates the settled water turbidity frequency plot.
Settled water turbidity has been improved from meeting a 2.0 NTU 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 results for finished water turbidity frequency plot. The plant performance
increased from achieving a 0.1 NTU approximately less than 5 percent of the time to
achieve a 0.1 NTU over 100 percent of the time.

B. Benefits to the District and Its Customers
The Texas Optimization Program demonstrated that the Brown County Water
hnprovement District #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 rule proposals which are anticipated to be promulgated in November of
this year. The optimization program also had several other side benefits. including raising
the public confidence and awareness of the public water supply and recognition of the
plant's operating staff's excellent capabilities. Monetary benefits were derived from
chemical optimization and less plant down time due to pre-planning and closer attention to
process controls.
C. Brown County Water Improvement District #1 Receives Top Award for
Drinking Water Quality
The Texas Natural Resource Conservation Commission (TNRCC) honored the Brown
County Water Improvement District #1 on May 13. 1998, with a state award under this
new program recognizing outstanding drinking\vater quality. Although the "District
already met regulatory standards at its drinking water treatment plant in 1996, the District
initiated a voluntary review of its facility. The evaluators from the Texas Engineering
Extension Service and Texas Co-Op Utility Program conducted a comprehensive
performance evaluation of the treatment facility. The District entered the Texas
Optimization Program and achieved significant improvements in drinking water quality.
As a result the turbidity of the water currently leaving the treatment facility is more than
five times lower than current state requirements. The treatment plant has demonstrated 1
that it will be able to meet the pending more stringent regulations.
D. Partnership for Safe Water Program
The American Water Works Association (A WW A)/US Environmental Protection
Agency (EPA) Partnership for Safe Water Program consists of the following steps:
Phase 1: Sign Up
Phase 2: Data Submission (one year turbidity date)
Phase 3: Self-Assessment and Correction
Phase 4: Third-Party Assessment and Correction
...
The major difference between the partnership for Safe Water Program and the Texas
Optimization Program is the requirement for the Phase 4 third-party assessment and
correction.
It is likely that Texas plants which participate in the voluntary Texas Engineering
Extension Services (TEEX) comprehensive performance evaluation (CPE) program will
satisfy the Phase 4 requirements for a third-party assessment.
