<br />(:48() <br /> <br />Operation, Maintenance, and Replacement <br />Annual maintenance costs for canals were estimated based on similar <br /> <br />irrigation canals in Federal irrigation districts. Maintenance of <br />diversion dams was also based on experienced costs for similar <br />structures in Federal projects. <br /> <br />Onfann Costs <br /> <br />It was assumed that all "new" water yield from the recharge alternative <br /> <br />would be pumped from the aquifer for irrigation by "new" wells and <br />pumps, which would be installed by fanTI(~~ers or operators. <br /> <br />0\-'~ <br /> <br />The wells and pumps were sized tCY,'Srve 8b~cres, each pumping from <br />" ",'> <br />", 'v <br />a depth of 50 feet.

The average cost per acre-foot pumping from a <br />50-foot depth is $3.99 which represents 125 kWh. The total energy <br />use' for 45,700 acre-feet would be 5,700 MWh/year with a maximum <br />power demand of 6 MW. <br />
