However, the reduction in <br />system losses could be somewhat offset if treatment facilities <br />are constructed as part of the improvements. Table IV-l shows the <br />treated water requirements used herein. If wells are continued as <br />the source of supply, the raw water requirements will be essentially <br />the same. <br /> <br /> TABLE IV-l <br /> TREATED WATER REQUIREMENTS <br />APPROXIMATE AVERAGE MAXIt~UM 2 ANNUAL <br /> DA Y USAGE 1 <br /> DAY USAGE (acre <br /> 3 4 5 <br />YEAR POPULA TI ON (gpm) (mgd) ~ (mgd) (mg) feet) <br />1977 832 115 0.166 289 0.416 60.74 186.4 <br />1980 1,050 146 0.210 365 0.525 76.65 235.3 <br />1985-1990 1,680 233 0.336 583 0.840 122.64 376.4 <br />1990-2000 2,300 319 0.460 799 1.150 167.90 515.3 <br /> <br />1.

Additionally, if <br />delivery of raw water varies on a year to year basis, sufficient raw <br />water must be purchased to assure that the minimum amount of raw <br />water for treatment is available each year. Raw water quantity re- <br />quirements as compared to treated water requirements must be evaluated <br />as it relates to type of treatment, source of supply, and delivery to <br />IV - 3 <br />
