<br />. <br /> <br />I)OH3' <br /> <br />. <br /> <br />. <br /> <br />Single-Purpose South Pl~tte River Plnn <br /> <br />18. On the assunpti,on tho.t the three preoeding pluns would be developed <br />in the order desnribed, the ultino.te munioipal water requirement of 20,000 <br />aore-feet by 1998, as estL~tod by the oity, would lack 5,000 aore-feet <br />of fulfillment. Bused upon the f~ther assur.~tion that no additional <br />supplies oould feasibly be developed on tho slopes of Pikes Poo.k, o.nother <br />souroe of supply would be the Eleven Milo Canyon Reservoir on the South <br />Platte River, 0. faoility owned nnd opornted by the City ane. County of <br />Denver. <br /> <br />190 Under this plan, water would be purohased from the potential <br />Blue-South Platte Projoot whioh would replacet by transnountain diversion, <br />the water tw{en from Denver's system. The purchased water would bo raised <br />approximtely 1,000 foet by punping to the. Catar.lOunt Creek watershed where <br />it woule. be assimilatee. into the existing Colorado Springs system. In <br />addi tion to the punping faoilities, the plan woule. require the construotion <br />of ~.o tunnols, and one oanal. An eastern_slope regulating resorvoir, <br />tentatively ie.entified as the ItNorth Catulnount aeservoir" on the map at the <br />back of this report, would be 0. desirable ade.ition to the system) however, <br />its eost is not inoluded in the subsequent fiscal analysis ef this plan. <br /> <br />20. Consideration has boen given to tho possibility of utilizing the <br />2,500-foot fall of the punpod water in the Catmnount Creek watershod for <br />tho preduotion of hydroeloctrio energy to bo used in the initial pUL~ing <br />operation. Preliminary o01:1putations ine.ioate that the amount of power so <br />produoed would be insuffioiont for tho pumping operation ane. the oost <br />would amount to about 10.6 mills por kilowatthour; wheroas, for tho pur- <br />pose of this stue.y, it was assumed that pryNer could be purchased at 5 <br />mills per kilowatthour. <br /> <br />21. Basee. upon an amortization of all construction costs over 40 <br />yenrs at 2-1/2 percent interest, the 'cost of operation nnd no.intonance <br />of all new faoilities, and the basic prioe for municipal wator of $20 <br />per ncre-foot at tho Eleven Mile Canyon Resorvoir, the cost of L'lUnicipal <br />wnter to Colorado Springs une.er this planwoulc. be 29.4 conts for each <br />thousand gallons or $95.83 per acro-foot. This price l~oes' not include <br />probable oosts that would ariso fr01n a necossary agreemont with tho City <br />and County of Denver pertaining to uso of Elevendilo Canyon Roservoir. on the <br />South Platte River. <br /> <br />Dual-Purpose South Platte River Plan <br /> <br />22. In lieu of the single_purpose plan which would PU!:1p only 5,000 <br />~cre-fe~t of wat?r from the Seuth Platte River solely for municipal use, <br />J.t wouIe, bo possJ.blo to punp froIn that source 45,000 acro-foot annually <br />of which 5,000 acre-foot would bo for municipal purposos and 40,000 acre- <br />feot would bo tor irrigation in tho Fountuin Vulloy. The el01~nts of this <br />plan are i~entical to thoso desoribee. in tho proooding single-purpose plan. <br /> <br />6 <br /> <br />
