3. Piping the ditch with 60 inch diameter plastic pipe for the first 3500 feet. Alternative No. 1 was considered unacceptable since it means the Missouri Heights - Mountain Meadow Irrigation Company will continue to lose water due to seepage. Alternative No. 2 was selected, since it is considered to be the least costly reliable approach. Alternative No. 3 this alternative is not feasible because there is not enough head to flow water through the pipe without backing water into the piping and structure of the reservoir embankment. The selected alternative, Alternative No. 2, involves purchase and installation of 3500 ft. of a new product which uses plastic interlocking peaces to line the ditch. Design has been completed by the suppliers of the product called Smart Ditch. This also includes needed concrete and other structural needs and rock riprap designed by the Garfield County Office of the Natural Resources Conservation Service (NRCS). NRCS is preparing any additional engineering designs and cost estimates for the project. Conceptual plans as prepared by the NRCS and Smart Ditch are attached in the back pocket of this study. The estimated cost of the completed project is $550,000. The cost breakdown is summarized in Table 1. The NRCS Preliminary Design report and detailed cost estimate are included in Appendix D.
