The <br /> <br />off-farm group ditches would be placed in pipe to preserve gravity pressure <br /> <br />and pumps would be added at the farm to develop sufficient pressure to <br /> <br />operate sprinklers for 9,300 acres being converted to sprinkler irrigation. <br /> <br />Pipelines, gated pipe, or ditch lining would be installed to reduce ditch <br /> <br />seepage from 1,850 acres of irrigated land not converted to sprinklers. <br /> <br />This plan can be implemented at a one-time construction cost of <br /> <br />$23,322,000. Technical assistance and administrative costs, estimated to be <br /> <br />$4,664,000, make a total installation cost of $27,986,000. <br /> <br />The Capitalized Annual cost including operation, maintence and <br /> <br />replacement is $3,304,900.!/ Capitalized annual net benefits are estimated <br /> <br />to be $420,200. <br /> <br />Implementation of this plan would not increase the amount of water <br /> <br />diverted annually for irrigation. Seepage from onfarm ditches would be <br /> <br />reduced by 3,OUO acre-feet and deep percolation would be reduced by 30,000 <br /> <br />acre-feet. Improved onfarm management of irrigation water would provide <br /> <br />54,000 acre-feet of water for consumptive use by farm crops throughout the <br /> <br />~~ <br />(J~\.~ <br /> <br />1/ Includes $23.0U per acre pumping costs for 9,300 acres. <br /> <br />V-ll <br />
