Water Main Pressure Management Systems

Given continued expansion of existing water systems and increasing water demands, often the pressure and flows on mainlines will increase in areas closer to the water source. This sometimes leads to older zones of water supply systems with pressures that cause continuing line breaks.

This was the case in three separate zones within the Gallatin area of the White House Utility District’s jurisdiction. CSR was contracted to provide survey, design, bidding and construction services to install the 3 separate installations of PRV’s involving 16”, 12” and 8” mains serving thousands of water customers. The professional services provided by CSR are further detailed in the General Scope of Work below:
