SUMMARY: While operating ASR over the 2017 ASR injection season, District staff noted that the valve controlling injection rate on the ASR 1 well was losing nitrogen gas at a steadily increasing rate from the injection valve control system. Following the close of the injection season, District staff investigated the source of the nitrogen leak at ASR 1 and with the help of a Baski Valve technician and determined the valve should be pulled from the well and sent back to the manufacturer for repair. Following inspection of the valve, District staff was informed the valve was damaged beyond repair and will need to be replaced. ASR 1 cannot function as an injection well without this downhole valve.
RECOMMENDATION: Staff recommends the Committee to recommend to the Board to enter into an agreement for
$70,000 with Baski to manufacture and deliver the downhole flow valve for ASR
1.
BACKGROUND: In the winter, District staff operates the ASR 1 well to inject excess Carmel River flows, and in the summer, CalAm operates the wells as sources to their distribution system in order to shift production from the Carmel Valley Alluvial Aquifer. Currently only ASR 1 has a permit from the Department of Drinking Water to be used as a source to the system. ASR wells 2, 3, and 4 are currently going through the permitting process to be used as sources to the CalAm system. ASR 1 cannot function as an injection well without replacing the downhole flow control valve.
IMPACT TO STAFF/RESOURCES: Funds for this project are included in the FY 2017-18 budget under “Water Supply Projects,” line item 1-2-1. Funds expended to complete this work will be reimbursed to the District by CalAm through the ASR Management and Operations agreement between the District and CalAm.
