Upper Lakeview/Rigi Pressure Reducing Valve (PRV)                      01/25/19

Project Description and Cost Detail        

Scope Described

Update PRV set up by separating the lines between the zones covered by this PRV.  This project is a high priority as customers are negatively impacted by water pressures in this zone.  Separating the lines will allow for reduction of pressure to customers on Lakeview and Oak Ridge while maintaining and supplying adequate pressure to customers on Upper Lakeview.   

Separation of lines into 3 segments complies with the 2005 Water System Master Plan as well as allows for improved metering of zone to aid in leak detection and updates valve access when reading meter.  Also allows for improved access when an adjustment is needed to the PRV for pressure stabilizing within zone.
