SUMMARY:  Staff proposes to retain CLA-VAL Western Regional Service to service CLA-VAL pressure reducing and pressure sustaining valves at the Santa Margarita Facility. Funds expended to complete this work will be reimbursed to the District through the Aquifer Storage & Recovery Project Management and Operations agreement between the District and California American Water (CAW).  The requested amount is larger than the quote to include a 10% contingency for replacement parts that are not covered in the quoted rebuild kits and an estimate for tax.  The last service of these valves was June 2017.

 

RECOMMENDATION:  The Finance and Administration Committee should recommend the Board authorize the General Manager to enter into an agreement with CLA-VAL Western Regional Service to complete the five-year maintenance of the CLA-VALs located at the Santa Margarita ASR facility.

 

BACKGROUND:  During the ASR injection season, portions of the CAW Monterey Main System are being used for water storage and transmittance of water diverted from the Carmel River and delivered to the ASR injection facilities.  Because the system is also supplying water to CAW customers, it is subject to daily and seasonal variations in customer demand.  Changes in demand result in pressure variations to the water delivered at the ASR facilities.  Pressure reducing and pressure sustaining valves help to maintain constant injection rates and protect the ASR wells from spikes in system pressure.  This equipment requires servicing from approved contractors every five years in order to maintain guarantee of functionality.
