Project: MCC Water System Capacity Analysis
Client: Middlesex County College
 |
MCC is a two-year community college
located in Edison,
Middlesex County, NJ
on an approximate 182 acre portion of the former Raritan Arsenal site.
The College was experiencing problems with water quality (taste, color
and odor) and water quantity (flow and pressure) in its on-site combined
domestic and fire water system. As a result of the problems and the experience
associated with system observation and maintenance, MCC could not proceed
with a multiple building fire sprinkler project. The College determined
that cleaning and lining of the majority of the mains in the existing
system (approximately 14,000 linear feet) is required and an engineering
analysis of the system was necessary to evaluate the accuracy of the College’s
Water System Plan, and other possible improvements (valve replacements,
water main extensions, etc.). GSE was retained by the College to determine
the water distribution system improvements required to allow the system
to operate in accordance with current Federal, State and Local standards.
As a result, GSE went on to perform targeted field tests along the College’s
water distribution system in order to better identify the possible causes
of the limited operating pressures and aesthetic water quality concerns.
These tests included water main coefficient testing to assess the internal
condition of the representative sections of the College’s water
distribution system and fire flow tests to assess system behavior in performing
the necessary hydraulic analyses. The results of the subject testing resulted
in the identification of specific water distribution system improvements
required to bring the existing fire protection systems to operate within
acceptable parameters. The improvements included water distribution main
cleaning and cement mortar lining, strategic valve and hydrant placement
and water main looping. This study was the initial stage that led to final
design and construction of the necessary improvements. The system is now
running efficiently and within acceptable standards.
