ITEM SUMMARY:
A hydraulic water model is a computer simulation of a water system. Through the help of specialized
software, such as WaterCAD, a water distribution system is modeled as a “network”; this modeling can
include details such as pipe material, pipe size, length of pipe, system demand, etc. The water model is
used to analyze our water system. In addition, it assists in narrowing alternatives for future/proposed
developments or system improvements. This modeling allows staff to simulate various operating
conditions in the distribution system without causing damage or interrupting existing service.
Our original water model was developed when the Water Treatment Plant was constructed in 2005. The
last update to our water model was performed in 2011 when a Water Tower Study was completed. The
results of that Study indicated additional water storage was needed. With additional development and
changes to the water system in the past decade, we need to update our water model to correctly analyze
our future water system storage needs and system demand. In the fall of 2021, staff requested proposals
from several qualified engineers to perform this update. The update will include:
1. Incorporate watermain modifications since 2011.
2. Update fire flow requirements (flow and residual pressure).
3. Calibrate Model - Once the model is updated, it will be calibrated by taking static pressure
measurements at 15-minute intervals at approximately 30 fire hydrants throughout the City.
4. Troubleshoot the model to ensure accuracy.
5. Prepare current water usage and population projections. As part of this project, water usage
projections will be upgraded based on historical water usage and CMAP population projections.
6. Evaluate the existing water distribution system
7. A draft report will be prepared and submitted to the City for review. The final report will
include an electronic copy of the water model.

8. Engineers will develop a future water system model. Future water demand requirements will be
based on the City's anticipated development. The model will then be used to determine the future
water distribution system pipe network required to provide adequate system pressure and fire flow
