Upper Lakeview/Rigi Pressure Reducing Valve (PRV) pit        12/20/18

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. 

Cost Detail

$36,140 as shown on spreadsheet for PRV pit #1

$34,700 as shown on spreadsheet for PRV pit #2

$34,700 as shown on spreadsheet for PRV pit #3

PRV pit #1 proposed for 2019; remaining work to be proposed for future years.   

Funding will be from water usage fees. 

All figures are from contractor quotation and equipment price from the supplier; ledge blasting is estimated.  If the $5,000 for ledge removal is not used, the funds will be placed into the water system Capital Reserve Fund.
