A procedure based on efficiency increase was used to determine <br /> <br />the pressure charge and was derived as follows: <br /> <br />Surface irrigation <br />requirement/acre <br /> <br />sprinkler irrigation <br />requirement/acre <br /> <br />= increased <br />efficiency <br /> <br />Increased <br />efficiency <br /> <br />value of = pressure charge/ acre-foot <br />water/acre-foot <br /> <br />x <br /> <br />Existing water supply <br /> <br />x pressure charge <br />/acre-foot <br /> <br />total pressure charge <br /> <br />2.52 - 1.86 = .66 <br /> <br />.66 x $16 = $lO.60 <br /> <br />1900 x $10.60 = $20,140 rounded $20,000 <br /> <br />An annual charge of $10.60 per acre-foot should be levied for pres- <br /> <br />surizing the existing water supply of 1900 acre-feet for a total of $20,000. <br /> <br />Account Charge <br /> <br />If there is strong indications that the project area at sometime in the <br /> <br />future may be divided into small tracts the sponsors may want to consider an <br /> <br />account charge. A uniform account charge is a method of increasing project <br /> <br />revenues as full-time farms are broken up into smaller units. For example, <br /> <br />the annual account charge could be based on the full cost to deliver water to <br /> <br />one acre amortized over the life of the project. <br /> <br />Total Irrigation Revenues <br /> <br />-rh ~,t <br />T.Me <br /> <br />~.e. <br />Total annual revenues available from irrigation ~ $229,000. <br /> <br />includes $209,000 from the sale of project water and $20,000 from pres- <br /> <br />surizing existing water in the project system.
