Lost hills water district lhwd is located in western kern county, california, in the southern end of the SAN joaquin valley the service area 1 canal reservoir lining project includes installation of high density polyethylene hdpe liner to line two reservoirs in the canal system to reduce seepage and improve water reliability the project also includes promotion of natural resource conservation service nrcs on farm water conservation programs to lhwd growers the estimated reduction in seepage from hdpe lining is 158 acre feet AF per year promotion of nrcs programs is also expected to result in more than 158 AF of additional water savings energy savings will be realized, and greenhouse gas emissions reduced by eliminating the need to replace the lost water with other supplies those supplies would also be pumped through state and federal water project pumps as well as the district S pump station and from water banks the lhwd participates in activities to be performed mobilization and site preparation contractors shall locate existing utilities and mobilize equipment construction sediment and asphalt lining shall be removed from the reservoirs the reservoir subgrade and anchor trenches shall be prepared, reservoir lining shall be installed, and anchor trenches shall be backfilled in accordance with the plans and specifications performance testing and demobilization reservoir lining shall be tested in accordance with the specifications projected deliverables or outcomes the lining shall reduce seepage, increase water reliability, reduce maintenance efforts, and reduce the potential for reservoir breaches seepage losses are especially detrimental because water supplies are very limited, and the lost water goes into the region S salty shallow groundwater rather than recharge an aquifer that has beneficial use intended beneficiaries lost hills water district S lhwd reservoirs 1 1A and 1 3 were built with asphalt slope protection and clayey soil bottoms in 1968 during construction of the original district distribution system the reservoirs help to regulate flows in the service area 1 canal system reservoir 1 1A has an area of approximately 3 1 acres 135,000 square feet and reservoir 1 3 has an area of approximately 1 13 acres 49,200 square feet under this agreement, the recipient shall install hdpe liners to line two reservoirs in the service area 1 canal system subrecipient activities if known or specified at time of award N a
