When we budgeted for the raw water line during the contract negotiations stage, the
scope of the raw water line design project was from Lake Georgetown to the water
treatment plant, using the plans developed by Haynie and Kallman, Inc., in 1990 as a
reference. On those plans, the raw water line is shown as terminating near the plant
entrance gate. After we started working on the project, we were directed to continue
the new water line into the water treatment plant and design a new flow inter /flow
control valve system to provide a redundant feed into the plant and increase flexibility
of water feed into the plant. This became desirable because the existing flow control
arrangement failed twice during the summer of 1994, causing the plant to be out of
service.
Developing the design and specifications for the additional 1,000 feet of pipe, the
venturi flow meter, the flow control valve, and the reinforced concrete vault can be
completed within the budget established for the existing job. However, developing the
electrical and instrumentation design and specifications cannot be accomplished within
our present budget. On October 12, 1994, Mr. Omar Naji visited the water treatment
plant site and the electrical building at Lake Georgetown to develop a scope and budget
for providing the electrical and instrumentation design. Mr. Naji has estimated that the
electrical and instrumentation work would be completed using four drawings as listed
below:
1. Process & instrumentation Diagram Drawing
2. Instrumentation Loop Diagrams
3. Electrical Site Plan, Vault Plan and Control Room Plan
4. One Line Diagram, MCC and Lighting Panel Modifications
The cost to prepare the drawings and specifications for the electrical and instrumentation
work is estimated to be $12,000.00.

At the request of Mr. Steve Miller, we are transmitting a proposal to perform a water
treatment plant evaluation on the City of Round Rock's existing water treatment plant.
The proposal was prepared after visits to the existing plant, discussions with Mr. Steve
Miller and Mr. Bruce Levens, and after preparation of preliminary calculations on the
existing plant's capacity.
The existing treatment plant is rated at 18 MGD, but this summer, during high water
use days, the plant was having difficulty treating 15 MGD. As the City continues to
grow, and its potable water demands also grow, it is vitally important that the existing
water treatment plant be able to produce a minimum 18 MGD. Therefore, there are two
purposes of the plant evaluation:
1. to determine what improvements are necessary to allow the plant to
comfortably operate at a max day rate of 18 MGD; and
2. to evaluate the existing operations of the plant and make
recommendations that would improve the water quality while
streamlining the existing operations.
In order to prepare this type of evaluation, data collection and data analysis in excess
of what has been already been done is required. The proposal describes this work effort
which would be directed by Mr. Danny Shannon. Mr, Shannon is a senior engineer
with CDM and has directed similar work efforts for the City of Fort Worth and the City
of Austin. Mr. Shannon would be assisted by Mr. Greg Swoboda, a professional
engineer located in our Austin office who has assisted Mr. Shannon with his work at
the City of Austin's Ullrieh Water Treatment Plant. The scope of the study is detailed
in the attached proposal as well as the man hours scheduled for both Mr. Shannon and
Mr. Swoboda.

The cost to prepare the plant evaluation is detailed in the proposal and totals

the project would have the Plant Evaluation Report submitted by January 31, 1995 and
the Operational Guidelines submitted by February 28, 1995.
If you have any questions during your review of the proposal please call me and I will
pass those questions on to Mr. Shannon.

Camp Dresser & McKee Inc. (CDM) has performed a brief review of the Round
Rock Water Treatment Plant to evaluate the existing hydraulic and treatment
capacities. This review indicates that the plant is hydraulically limited to a
maximum flow of about 15 mgd. The City has requested CDM to perform a
more extensive study of the plant facilities to determine what modifications can
be made to upgrade both the hydraulic and treatment capacities without
expanding the number of clarifiers and filters. In addition, the City has asked
CDM to provide on -site field assistance to work with the City operations staff
in evaluating potential operational modifications to the plant which may assist
in providing better treatment. This proposal separates the proposed work into
three tasks: Study; Operational Assistance; and D ign. A synopsis of each task
is presented below: 6 .0.6
Task 1 Study
The first activity of Task 1 (activity 1.1) will be to conduct an on -site plant
evaluation. CDM will review the current plant operations with the City staff
to understand the operational philosophy. CDM will then conduct a review of
existing treatment facilities to verify the actual field conditions in relation to the
City's available construction drawings. The review will only be conducted for
existing treatment facilities critical to conducting hydraulic and process
evaluations. This will include field verification of various structure dimensions,
elevations of control weirs and gates, arrangement of equipment, piping, and
valves, and other items which may be different than as shown on the plans.
CDM will also survey the existing equipment and develop an inventory list to
include the sizes, capacities, and condition of equipment.
The second activity (activity 1.2) will be to perform a hydraulic evaluation of the
plant facilities based upon the existing plans and the data obtained from activity
1.1. CDM will develop a hydraulic model of the existing facilities and verify the
model at the plant by measuring various water levels throughout the plant. We
will then determine what improvements are needed at the plant to increase the
hydraulic capacity to various flow rates. These proposed modifications will be
input into the model to determine the theoretical effect on the overall hydraulics
at various flow rates.

The third activity (activity 1.3) will be to evaluate the existing treatment process
to determine what the existing facilities can currently treat and what
modifications can be made to improve treatment and increase the treatment

capacity. CDM will concentrate primarily on mixing, flocculation and
clarification, and filtration.
The culmination of the study phase of the project will be a report presenting the
evaluations performed and making recominendations for expanding the plant
capacity. Preliminary drawings and cost estimates will be provided.
Task 2 - Operational Assistance
Under activity 2.1 CDM will provide on -site assistance to the plant operations
staff to conduct various field studies and evaluations to improve the plant's
process and treatment performance. Such items which may be evaluated
include alternative polymer additions and locations, mixing alternatives, filter
backwash procedures, filter backwash operations, and other ideas which may
be developed by CDM and City staff. CDM will provide 40 hours of on -site
assistance for this activity.
Based upon the studies conducted under activity 2.1 and the results and
findings from Task 1, CDM, with input from City staff, will develop a set of
operational guidelines to assist the plant staff in the day -to -day operation of the
plant.

SUBJECT: City Council Meeting, November 10, 1994
ITEM: 10D, Consider a resolution authorizing the Mayor to enter into an
agreement with Camp Dresser & McKee, Inc. for water
treatment plant piping and control engineering services.
STAFF RESOURCE PERSON: Jim Nuse
STAFF RECOMMENDATION:
During peak usage at the water treatment plant, some processes were stressed
when producing the maximum rated output. Staff is requesting that Camp Dresser and
McKee, Inc. be hired to explore the operation and recommend improvements to our
production process. This Is a complex task due to the nature of the water treatment
process. We believe that CDM has the expertise to do this important engineering
service. Additionally, due to three major breaks in the raw water line this year, staff
feels it is prudent to extend the raw water line all of the way to the plant itself instead
of tying Into existing lines inside the facility fence. This would provide us with a
completely separate /dual water delivery system.
