<br />and 12 partial supply contract providers; the City of Englewood; and other small
<br />providers in the Bear Creek basin. The main sources of supply available to the this sub-
<br />region consist of native South Platte River water, transmountain diversions from the
<br />Blue, Fraser and Williams Fork Basins and water reuse, Non-tributary groundwater is
<br />available but not used to any significant degree, Water conservation measures also are in
<br />place and serve to reduce demand,
<br />
<br />Denver's Near Term resource strategy, as developed in its Integrated Resource Planning
<br />process, is projected to yield 401,000 acre-feet compared to a raw water demand at build-
<br />out of 445,000 acre-feet, including a 30,000 acre-foot safety factor. Denver therefore has
<br />a remaining need of 14,000 acre-feet, excluding this safety factor, Denver anticipates
<br />meeting this remaining need through additional water conservation, potable reuse and
<br />development of additional supplies through the use of its water rights, which could be
<br />achieved by Denver alone or through cooperative actions with others, Denver has
<br />sufficient potential yield from its own water rights to meet its build-out needs and
<br />obligations, Denver has not yet chosen a specific long-term water supply strategy, and
<br />remains interested in additional water conservation, effluent management, conjunctive
<br />use, and additional surface storage to meet its long-term needs.
<br />
<br />The City of Englewood, included in this sub-region, does not anticipate significant
<br />growth in its water demands and has sufficient existing water supplies to meet its ultimate
<br />future water needs, projected to be about 8,500 acre-feet per year.
<br />
<br />The South Metro Sub-rel!ion includes the water provider members of the Douglas
<br />
<br />County Water Resource Authority2 and other small providers in Douglas and Arapahoe
<br />Counties. Throughout this sub-region, Denver Basin groundwater is the primary source
<br />of supply.
<br />
<br />The build-out water demands for this sub-region are projected to total about 127,000
<br />acre-feet per year (exclusive of those providers supplied by Denver and Aurora). Water
<br />providers in this sub-region have sufficient decreed groundwater rights, surface supplies,
<br />reuse/augmentation plans and contract deliveries to meet their projected build-out needs,
<br />There is no significant unmet need projected for this sub-region, assuming that Denver
<br />Basin groundwater will continue to be used as a major water supply source.
<br />
<br />However, the sub-region is actively working to increase the renewable portion of its
<br />water supplies by employing effluent management approaches that would maximize the
<br />reuse of its groundwater return flows, and by acquiring additional surface supplies, The
<br />region is particularly interested in expanding the roles of reuse and conjunctive use of
<br />surface and groundwater as ways to reduce its future use of Denver Basin groundwater,
