<br />Cj <br />--.1 <br />~.. situations in which EET development might be constrained by compact considerations. <br />CJ <br /> <br />Improvements in the Efficiency of Water Use by Others <br /> <br />Yet another means of supplying water to EET's is improvements in the <br /> <br />efficiency of use by non-EET uses. This alternative is a potential source of <br /> <br />supply in that reductions in the projected demand for water for non-EET uses <br /> <br />would effectively increase the supply of surface water remaining for EET's. <br /> <br />Municipal Uses. Within the Upper Basin itself, municipal uses are projected <br /> <br />to account for less than 2 percent of future depletions. Obviously, any <br /> <br />reductions in consumption by improving the efficiency of use in this regard <br /> <br />would be insignificant. Rather, the greater opportunity for reducing depletions <br /> <br />in the municipal sector lies outside of the Upper Basin in the urban areas which <br /> <br />import at least a portion of their supplies from the Upper Basin. <br /> <br />For example, if one assumes no municipal recycling of water and a 20 percent <br /> <br />reduction in per capita use by .only that increment of population growth that is <br /> <br />the basis of, projected increases in exports, a reduction of 60,000 to 80,000 <br /> <br />acre-feet per year in projected exports could be achieved. Obviously, this is a <br /> <br />highly conservative estimate. If one takes into account the fact that techniques <br /> <br />to reduce per capita consumption would apply to all customers, not just projected <br /> <br />increments of population growth (i.e., new customers), then exports for municipal <br /> <br />use could perhaps be reduced by as much as 200,000 to 300,000.acre-feet per year. <br /> <br />If recycling were employed, or if reductions in per capita consumption exceeded <br /> <br />20 percent, exports could be reduced by even larger amounts. <br /> <br />While the savings appear to be potentially substantial, they would be of no <br /> <br />avail in the subbasin which would be most impacted by future EET developments, <br /> <br />since exports of water from the White River Basin are not anticipated in the future. <br /> <br />Rather, the important aspect of potential reductions in exports insofar as water <br /> <br />availability for EET's is concerned is that such reductions could alleviate possible <br /> <br />c~ <br />
