<br />designed to be about 20 feet deep which would provide <br /> <br />necessary for 50 years of salt accumulation. The total <br /> <br />area would be divided as follows: <br /> <br />Stage I Ponds <br />Stage II Ponds <br />Stage III Ponds <br /> <br />the storage <br />evaporation <br /> <br />298 acres <br />166 acres <br />148 acres <br /> <br />Total <br /> <br />612 acres <br /> <br />Shapes and sizes of evaporation ponds would vary to confonn to <br />the topography and the scheme of operation. Flow of brine from <br />pond to pond would be by gravity. <br />9. Replacement Water. Water to replace that used in the <br />desalting process would be provided to the WPRS by three canal <br />companies who divert from the river for irrigation. <br /> <br />B. Project Cost Analysis <br />1. Investment Costs. Investment costs of the La Verkin <br />Springs Unit include Federal expenditures for construction, and water <br />rights to bring the project to a stage of readiness for sustained and <br />reliable operation. Interest during construction is also included as an <br />investment cost. A summary of investment costs is presented in <br />Table 1, Investment Costs. These costs are feasibility grade <br />estimates developed by means of itemized costs, based on October <br />1978 construction prices. <br />2. Operation and Maintenance (O&M) Costs. These costs <br />consist of personnel (salary and wages), electric power consumption, <br />replacement parts, supplies and materials, equipment operation, <br />special O&M costs such as items unique to desalting operations, and <br />administrative and general expense. The October 1978 estimate for <br />annual O&M costs was $2.8 million per year. <br /> <br />. <br /> <br />002520 <br /> <br />11 <br />
