Raw water is diverted from the river at the <br />united States Bureau of Reclamation (USBR) recently constructed <br />tunnel. After leaving this tunnel, water flows through approximately <br />one mile of open canal to the USBR diversion structure. Water then <br />flows into an unlined portion of canal owned by the Montezuma valley <br />Irrigation Company to the intake of an existing transmission line <br />owned by the Ci ty of Corte z. This pipe 1 ine was constructed in 1949 <br />and connects the unlined irrigation canal to the City reservoir at <br />the Cortez Water Treatment Plant. <br /> <br />The purpose of this feasibility study is to evaluate the existing <br />raw water facilities, determine what improvements are necessary, <br />evaluate alternative pipeline alignments, and investigate the <br />feasibility of hydroelectric power generation on the raw water <br />pipeline. <br /> <br />Authorization <br /> <br />This feasibility study was authorized by an agreement dated April <br />I, 1985, between the Colorado Water Conservation Board (CWCB) and <br />Brown and Caldwell. Work under this agreement, project number 2280, <br />Raw Water Supply Feasibility Study, was authorized to proceed on <br />September 12, 1985. Exhibit A of the agreement describes in detail <br />the scope of work for consultant services. <br /> <br />To accomplish the goals of this study, work was organized into <br />several distinct tasks. Familiarity with the existing system was <br />accomplished by collection and review of previous reports, maps, <br />operating records, and other relevant data. Existing facilities were <br />inspected and City staff consulted on existing system conditions, <br />problems, and planned improvements. The study tasks described in the <br />scope of services include the following: <br /> <br />1. Evaluation of <br />pipeline. <br /> <br />condition and expected <br /> <br />life of existing <br /> <br />2. Identification of new pipeline alignment corridors and <br />selection of the most feasible alignment. <br /> <br />3. <br /> <br />Determination of <br />and industrial <br />generation. <br /> <br />a new pipeline size necessary for municipal <br />water usage and for effective hydropower <br /> <br />BROWN AN D CALDWELL C <br /> <br />CONSULTING ENGINEERS <br />
