Water Distribution Network Analysis
City of White Plains, New York

The City of White Plains retained J. Robert Folchetti & Associates (JRFA) to develop a new computer model for the City water distribution network. It was the City's desire that the new model could be used for determining system operating conditions both now and in the future. JRFA's approach to the project was to develop a fully dynamic hydraulic model that would be compatible with existing coordinates and thus could be incorporated into the City's GIS system. It was the City's goal that their new model would be able to forecast flow from hydrants located throughout the City under various operating conditions. They also desired that the model be able to determine the optimum pipe size for individual service lines. JRFA set about developing a computer program to meet these objectives.

JRFA prepared the model using KYPIPE2000 software which was fully compatible with the City's Windows operating system and GIs software. The tasks included the following:

•   overlay of the City's GIs mapping system into the KYPIPE2000 program
•   input of minor loses throughout the City's water system into the base model
•   development of a hydraulic model of the City's water system using KYPIPE2000, including: 

• friction factor review and revision
• water supply sources
• water use records
• development of future water demand estimates
• review of existing system to meet future demands
• on-site calibration tests of new model through selective field testing

•   production of a final report documenting the results of the hydraulic analysis along with identified required
    capital improvements and associated costs
