Water Distribution System Master Plan
Ken:
As we discus;ed by telephone a couple of weeks ago, we understand you would like us to "take possession" of
the water distribution system analsysis and master plan. As such, we have made minor modifications to our
scope of services for the Water Distribution Master Plan analysis and report. The attached revised letter
proposal outlines our scope of the project and understanding.
We hope this meets your intent. Please review and give me a call so that we may discuss our understanding of
the project further.

Re: Water Distribution System Master Plan Update
Dear Mr. Griffin:
As you requested in our recent meeting with you, we are pleased to submit this proposal for professional
engineering services for the Water Distribution System Master Plan Update and Hydraulic Analysis. The
current hydraulic model was last updated in May 1997 by our firm, and was based on the data set(s) created
by Rady & Associates in December 1994. The purpose of this master plan analysis is to re-visit the
assumptions made and technical approach used in the last report, re-evaluated the master plan and make
specific recommendations for proposed system improvements in report form, graphically on a new master
plan map and in the electronic data files. We understand the City of Coppell currently has a single use license
of Cybemet 3.0 software for a 2000 pipe system.
Our engineering services for this project shall include the following:
I. BASIC SERVICES:
PRELIMINARY PHASE
A. Convert the City's current water distribution system hydraulic model data set to the Cybemet
version 3.0 hydraulic model, including both existing system and build-out scenario models.
Evaluate both the maximum hourly and minimum hourly unit demands based on:
1. Available water records provided by the City.

2. Current population estimates and projections provided by the City in the recent City of
Coppell Comprehensive Plan.
3. Existing and projected land use assumptions provided by the City in the recent City of
Coppell Comprehensive Plan.
B. Update the existing system model, and the master plan model with the revised demands. Apply
the hydraulic system demands based on existing and projected land use assumptions.
C. Model all existing pump stations utilizing actual pump flow data or pump curves, where
available from the City.
D. Add existing water lines to the model at the City' s direction and as required to properly evaluate
the existing system and the distribution system as it is envisioned at the build-out scenario.
E. Update both the existing system and master plan hydraulic map showing the water system
elements contained in the hydraulic model including:
1. Line sizes and numbers of critical lines.
2. Junction nodes and numbers.
3. Existing and recommend elevated and ground storage tanks.
4. Existing and recommended pump station layouts.
F. The master plan map will be prepared based on the electronic street map provided by the City of
Coppell.
FINAL REPORT AND EVALUATION PHASE
G, Evaluate and make recommendations for system improvements for the existing system and the
master plan. The evaluation is to include recommendations for:
· Alternative Water Supply Sources and Points of Delivery
· Elevated Storage Tanks
· Ground Storage Reservoirs
· Booster Pump Stations
· Pump Stations
· Distribution Lines

H. Prepare and deliver twenty five copies of the existing conditions water distribution map.
I. Prepare and deliver twenty five copies of the projected master plan water distribution map.
J. Prepare and deliver 25 copies of the water system master plan report including methodology of
the analysis, recommendations, schedules, and probable cost for system improvements. Ten of
the 25 copies of the water system master plan report will contain the computer analysis input and
output data sets in the appendix.
K. Deliver AutoCAD drawing files and associated Cybernet data files of the existing conditions and
master plan water distribution systems models. The electronic files will be delivered under the
following conditions:
1. The files are compatible with AutoCAD Release-14 by Autodesk, and Cybemet Version 3.0
by Haestad Methods. The Shimek, Jacobs & Finklea, L.L.P. does not make any warranty as
to the compatibility of these files beyond the release of AutoCAD Release-14 or Cybernet
Version 3.0.
2. Because data stored on electronic media can deteriorate undetected or be modified, it is
agreed that Shimek, Jacobs & Finklea, L.L.P. will not be held liable for completeness or
correctness of electronic media after an acceptance period of thirty days after delivery of
these files.
3. The electronic files are an instrument of Shimek, Jacobs & Finklea, L.L.P.'s service. Where
a conflict exist between the hard copy drawings, data printouts and the electronic files, the
hard copy drawings and data printouts will govern in all cases.
4. Both parties acknowledge mutual non-exclusive ownership of the electronic files and each
party may use, alter, modify or delete the files without consequence to the other party.
5. The electronic files provided to the City, do not contain engineers' seals, handwritten dates,
nor signatures.
N. Present the findings to the City staff and/or City Cotmcil as necessary.

D. Evaluation water distribution system improvements required to meet the needs of alternative
water supply and point of delivery scenarios. These are to be completed on a case by case basis
once the existing system model and master plan models are complete and acceptable to the City
of Coppell. As each scenario is analyzed, a brief letter report will be prepared which outlines the
results and recommendations.
E. Evaluation water distribution system improvements required to meet the needs of various
