<br />~l\lo <br /> <br />. <br /> <br />B. Alternative Alinements and Facilities <br /> <br />Several diversion sites and conduit alinements were studied and <br />evaluated in relation to difficulty of construction, economics <br />and the environment. The proposed alinement and alternative <br />diversion sites and conduit alinements considered are shown on <br />Figure IX-I, (Former Alinement Alternatives). <br /> <br />The Liberty Point alternative ran 4.3 miles from Pueblo Dam through <br />Liberty Point County Park before returning to the existing <br />alinement to Colorado Springs. This alternative was reevaluated <br />due to the detrimental effects the conduit and associated <br />facilities would have on the aesthetics of the park. See <br />Figure IX-2, (Liberty Point Alternative). <br /> <br />An alternate study to the proposed system involved the increased <br />heights of the first and second surge tanks and the location ~f <br />the second pumping plant. The first surge tank under the alternate <br />study would be approximately 130 feet high above ground compared <br />to the proposed height of approximately 65 feet above ground. The <br />second surge tank would also increase in height approximately <br />15 feet above ground and the location of Pumping Plant No. ~. <br />would be moved further north. The advantages of the alternate <br />include equal pumping lifts for Pumping Plants Nos. land 0 And <br />less foundation excavation for the first surge tank. Analysis <br />of the alternate's anticipated construction and operation and <br />maintenance costs indicated it was economically comparable to <br />the proposed system. Because of the associated visual 'mpact of <br />the h~ight cf the first Burge tank, the alternate was not adopted. <br /> <br />. <br /> <br />TIle former proposed Canon City alternative would have included a <br />diversion works near the east edge of Canon City, 18 miles Gf <br />trunkline conduit, 10 miles of laterals, 5 pumping nlants, and <br />numerous other related structures. After reevaluation, this <br />proposed route was replaced by the new Pueblo-Colorado Springs <br />alinement. <br /> <br />Reasons for the relocation were ease of construction, elimination nf <br />sand and silt problems which would be encountered at the Canon ~ity <br />intake, availability of Colorado Springs-owned water 'reatment <br />plant site, and the new alinement being more compatible <<ith <br />cities' future plans and water distribution systems. <br /> <br />IX-2 <br /> <br />. <br />
