WATER SYSTEM ANALYSIS
LOGICAL PROGRESSION OF TASKS
NOTE: Rady and Associates will work closely with the city to ensure all requirements
are satis~od and client expectations are met in a timely fashion.
A. Dam Collection: System 1) Identify location, type, age and size of existing piping network
2) Identify location, size, and overflow elevations of water towers
3) Identify location and size of ground storage tanks and pumps including
head discharge relationships and any instrumentation/operation
parameters
4) Identify locations and characteristics of pressure regulating valves and rate of flow
controllers
5) Identify pressure plane boundaries
6) Obtain topographic map of service area
7) Identify locations and capacity of water supply sources ie. wells, water treatment
plants, and outside purchases
8) Obtain population, number of connections, and land us~ (current and future
projections) for the city
9) Identify water conservation measures
B. Data Collection: Water Demands
1) Locate historical water use and pumping records
a) Annual demands: average day, max. day, max. hour, and diurnal distribution
b) Identify large volume users
c) Obtain sampling of meter books to determine average water demand per type
of connection
d) Include any periods of water rationing or other unusual circumstances
2) Obtain land use map and meter book
C. Development and Calibrate K-PIPE model 1) Work with fire/water department personnel on planning and performing flow tests
2) Obtain status of every pump and elevated tank simultaneously with the checking of
residual pressure and flow at selected locations
3) Obtain water demand for the days of flow testing
4) Prepare computer model for system
5) Calibrate computer model against flow test results

D. System Analysis
i) Existing system evaluation
a) Evaluate supply sources and water system components ie. elevated tanks,
ground storage tanks, pumps, and t~nsmission lines against Texas Water
Commissica~ Rules and Regulations, insuranc~ industry standards, and specific
syst~rn d~rnands using present max. day demands and an e,xtende~ I~riod
simulation which includes max. hour and five flows sul~rimpose, d on max. day
a~nd average hour demands
b) Determine sys~m deficiencies and potential ~cernedial solutions
2) Evaluate futur~ conditions and system improvements needed to me~t fur-axe system
requirements (see 6a.)
3) Incorporate future requin~ments into present system and dm~elop a system
improveme, at plan that is compatible with future system requirements
4) Prepare a cost projection and capital improvement plan to implement the selected
course of action
E. Report
1) Prepare final report outlining the evaluation, re, commendations, and selected plan
for final approval by the city. As stated above Rady and Associates will work
closely with the city and communicate on a regulax basis the status of the analysis.
