The development of the <br />recommendations is presented in the following chapters of the <br />report. This report has been reviewed with the staff of the Colorado <br />Water Conservation Board and the City of Cortez. <br /> <br />Raw Water Supply pipeline Study <br /> <br />The existing raw water supply pipeline between the east lateral <br />of !1ain Canal No. 1 and the Cortez Water Treatment plant was <br />constructed in 1949. Water supply transmission facilities to the <br />head end of this pipeline have recently been improved as part of the <br />Dolores Water Supply project. The City of Cortez is presently <br />upgrading its facilities at the Cortez Water Treatment plant. The <br />capacity of the raw water pipeline has been reached several times in <br />recent years during periods of high demand, and maintenance acitivity <br />on the line has been significantly more than anticipated due to the <br />advanced stage of deterioration of the pipe material. The pipeline <br />has been in service for nearly 40 years. This pipeline represents <br />the only source of water supply for th", City of Cortez and as its <br />reliability has sharply declined, the need to plan for improvements <br />to, or replacement of, this line has become critical. <br /> <br />The purpose of this feasibility study is to evaluate different <br />options available for improving the raw water supply, by renovation <br />of the existing line, or by construction of a new line. If a new <br />line is the appropriate improvement, then an alignment evaluation <br />will recommend the selected route for a new line. A study of the <br />feasibility of installing a hydroelectric power generating station on <br />the pipeline is also part of this assignment. <br /> <br />Findings and Conclusions <br /> <br />The principal findings and conclusions of this feasibility study <br />are presented below. These findings are supported by the detailed <br />material presented in the body of this report. <br /> <br />1. The existing raw water pipeline has reached its practical and <br />economic life. <br /> <br />2. The physical conditions of the existing pipe material is so <br />poor that repair or renovation of the existing line is not <br />practical. <br /> <br />BROWN AND CALDWELL C <br /> <br />CONSULTING ENGINEERS <br />
