<br />. <br /> <br />. <br /> <br />Total project costs for the Palo Verde subarea are estimated at <br /> <br /> <br />$24 million on the basis of January 1981 prices, exclusive of the <br /> <br />mitigation plan. This results in a cost effectiveness of about <br /> <br /> <br />$242,000 for each mg/L of salinity reduction at Imperial Dam making <br /> <br /> <br />it among the most cost-effective of the agricultural source control <br /> <br />units. The PVID Unit cost-effectiveness also compares very favorably <br /> <br /> <br />with the cost-effectiveness of point and diffuse source units (where <br /> <br /> <br />desalting and evaporation pond disposal are anticipated as the expected <br /> <br /> <br />strategy) that have a cost effectiveness in excess of $1.5 million per <br /> <br />mg/L at Imperial Dam. <br /> <br />In addition, studies are currently being made to examine the potential <br /> <br />for a ground-water flushing alternative. <br /> <br />The problems and needs of the Irrigation District are such that the <br /> <br /> <br />District would benefit not only from lining portions of their distribution <br /> <br />systems as a part of the salinity control program, but from lining all the <br /> <br />canals and laterals. Lining would provide adequate delivery rates for <br /> <br />most efficient water use, eliminate gopher damage and bank failures, <br /> <br />eliminate loss of water, and reduce operation and maintenance costs for <br /> <br />the District. If a hydroelectric generating facility were installed at <br /> <br />the Palo Verde Diversion Dam pursuant to legislation currently before <br /> <br />the Congress, the reduced diversion requirements of an improved distribu- <br /> <br />tion system would provide additional power generation benefits. The PVID <br /> <br />has indicated an interest in rehabilitating their entire distribution <br />system under a program similar to Water and Power's Rehabilitation and <br />Betterment Program. Authorization and studies would be necessary to <br /> <br />determine the amount Water and Power could cost-share on a portio~qf~ <br />uu~883 <br /> <br />2 <br />
