Increased di- <br />versions from the Upper Colorado Region to the <br />Wasatch Front of central Utah will meet requirements <br />there. Increases in diversions from the Upper Colo- <br />rado Region also will be made to meet demands <br />between Fort Collins and Pueblo on the eastern <br />slopes of the Rocky Mountains in Colorado. Desalting <br />plants will assist in meeting future needs, but pro. <br />cesses and costs for large-scale plants are speculative <br />at this time, The Lower Colorado base plan includes <br />several relatively small-scale plants to desalt brackish <br />water for municipal use. <br />Most of the rural domestic needs outside the <br />service areas of public water supply systems are met <br />by withdrawals from wells and little change in this <br />sector is expected. <br />No umnet needs for municipal, industrial or <br />domestic water will result from the requirements and <br /> <br />42 <br /> <br />plans projected for the area uniess Pyramid and <br />Walker Lakes are maintained at their 1965 levels. <br /> <br />Costs <br /> <br />The capital costs involved in providing for the <br />projected municipal .and industrial water require. <br />ments, shown in figure 7, are about $3.4 billion <br />during 1965.80, $2.8 billion during 1980-2000, and <br />$4.9 billion during 2000.20. Additional annual costs <br />for maintenance of facilities and treatment of water <br />increase from about $110 million during 1965.80 to <br />$394 rni1lion during 2000.20. <br /> <br /> II <br /> 10 <br /> 9 <br /> 8 <br />'" 7 <br />0:: <br /><t <br />...J <br />...J <br />0 6 <br />" / <br />"- <br />0 <br />'" 5 <br />z / <br />0 <br />...J <br />...J <br />III 4 I <br /> 3 <br /> 2 <br /> <br />o <br /> <br />1965 1980 2000 2020 <br /> <br />Figure 7.-Municipal and industrial water facility <br />instal/ation cost. <br />
