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 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, determined the leak in the nitrogen control system is occurring at the connection point of the valve, which is set at 420 feet in the well. Fixing the leak requires the valve to be pulled from the well by a well contractor. With the status of the valve, the well is not operable in recovery mode and CalAm cannot use the well as a source to the system. ASR 1 is needed to recover the ASR water banked from the 2017 winter flows and shift the pumping from the River to the Seaside Groundwater Basin. Due to the emergency nature of the repairs needed to restore the source to the CalAm system, the contract has been initiated prior to this meeting and the work is set to begin on Aug 14.
RECOMMENDATION: Staff recommends the Board ratify the General Manager’s decision to enter into an
agreement for $24,950 with Zim Industries to pull, repair and reinstall the
down hole flow valve in ASR 1.
BACKGROUND: The District and CalAm share the use of the ASR wells during operation of Aquifer Storage and Recovery. In the winter, District staff operates the wells 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.
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. Staff time will be utilized to provide project management and oversee field work.
