o Illl ~ ~ 5 The DWD's use of the DRCOG figures projects a six county metropolitan area population by the year 2000 of 2,461,000 which compares favorably with the Front Range estimate which is derived from the Colorado Division of Planning's estimates. Translating those population projections into probable water service demands results in the graph appearing on Figure 1. That Figure graphically contrasts the water service demands for different service concepts with'the presently available firm annual water supply of the Denver system (dashed blue line - 295,000 acre feet per year) . The blue dashed curve represents the water service demand projection expected to occur only within the City and County of Denver. The solid black curve represents a water service demand projection which can be expected from a continuation of the Board's present service area and tap limitation policy; with a continuation of current tap demand trends, it projects an average of only 4,200 new taps a year regardless of how large a population increase occurs in the metropolitan area. The green curve represents the water service demand projection likely to require service from the Denver system as a result of the generally accepted anticipated population growth projections within the entire metropolitan area without any artificial limitation on availability of taps or water service through them. The red curve represents the water service demand projection for the same population as the green curve without any limitation on the availa- bility of taps, but with the availability of water service through them limited to the amounts necessary to attain the demand reduction goals described in the Foothills Settlement documents. The question implicit in this factual presentation is to what degree should sound water system planning assume that those goals will in fact occur within the time frames set forth in those documents. The question is not whether diligent efforts will be made to achieve those goals, but whether, to what degree and when such efforts may be successful. The graph appearing on Figure 2 illustrates the gravity of the future metropolitan area water supply problems. As in Figure 1, the green bar graph represents the water service demand projection 1 ike 1y to require service from the Denver system, while the black bar graph represents the level of water service projected to result from the continuation of the Board's present service area and tap limitation policy. The solid blue horizontal line represents the firm water supply of 295,000 acre feet per year now available from the Denver system. The portion of the black bar graph an Figure 2 which is above the blue line graphically depicts the timing and magnitude of the water service -3-
