<br />f. <br /> <br />'r)! :;, <br /> <br />'% <br />.~ <br /> <br />-:;, <br /> <br />"-. <br /> <br />to the Kassler facility where the treated wastewater would be mixed with raw <br /> <br />; <br />". '~: <br /> <br />water entering the system. The combined wastewater and raw water would be <br /> <br />recycled through the system. A layout of this concept is shown on Fig. 2. <br /> <br />A second concept could be developed using the city of Aurora's future <br /> <br />diversions trom the Homestake ProJect. This concept could be used to pro- <br /> <br />vide water tor the development of a coal resource located southeast of <br /> <br />Denver. Deposits of lignite are located in the Sand Creek basin on the south~ <br /> <br />eastern edge of the metropolitan Denver area. A coal gas:Lfication facUity <br /> <br />has been suggested east of Aurora to develop the lignite resource. Treated <br /> <br />wastewater could be used in the development of this resource. <br /> <br />Water from the Western Slope would be diverted to the Aurora distribution <br /> <br />system via the Homestake Diversion ProJect and the Aurora supply aquaduct. <br /> <br />The water WQuld be used for domestic and industrial purposes and then dis- <br /> <br />Charged to the Aurora collection system. The water would then be treated <br /> <br />and pUlllped to a storage reservoir located on Sand Creek south of Aurora. The <br /> <br />';' <br /> <br />,i <br />" <br /> <br />storage reservoir could be des:Lgned to control flood runoff from the upstre8lll' <br /> <br />portions of Othe basin where mining operations would take place. When needed, , <br /> <br />the treated ,wastewater would be conveyed to the coal gasification facility <br /> <br />located sevetral miles east of the storage site. A diagram of this concept <br /> <br />is shown on :Fig. 2. <br /> <br />A third concept could be developed using the treated wastewater effluent <br /> <br />from the metropolitan area treatment facilities. This effluent could be <br /> <br />used to recharge a declining ground water aquifer in the downstream portiOns <br />of the Kiowa Creek and BiJou Creek drainage areas. Treated effluent would be <br /> <br />Ii <br /> <br />conveyed tr~ the metropolitan Denver area treatment facilities to the middle 0 <br />portions of Othe Kiowa Creek and BiJou Creek basins. At these locations, the <br /> <br />'.~ <br /> <br />-l> <br /> <br />treated effluent would be released into the Creeks and allowed to flow <br /> <br />11 <br /> <br />., <br /> <br />
