Sample Water Resources Projects - Continued Durango Water Supply Alternatives Investigation The City of Durango recently retained Boyle to assist in identifying, preparing conceptual level designs, and conceptual level estimates of costs for a range of water supply alternatives for meeting the City's future potable water demands. The City currently relies on a single water treatment plant for treating water from two sources, the Animas River and the Florida River. There are a number of alternatives available for future water supply, including contracting for supplies from the Animas -La Plata project, construction of a new reservoir and water treatment plant, and water exchanges on the Animas River. Boyle is preparing conceptual level designs for each of the alternatives, including pipeline alignments, tie -ins to existing water supply infrastructure, new and/or expanding water treatment capacity, and new reservoir construction. These designs served as a basis for estimates of capital, operation and maintenance costs, and a matrix facilitating the comparative analysis of the alternatives. Greeley Master Plan, Greeley, CO. Boyle Engineering Corporation was selected by the City of Greeley to assist in the preparation of a long -term master plan covering all aspects of the city's -- drinking water system.

Engineering services include evaluation of new and existing system components across three river basins, two treatment plants, and many miles of major treated water transmission pipelines. The master plan will serve as a roadmap to meet future water demands through 2050. Greeley Non - Potable Irrigation System Study, Greeley, CO The City of Greeley is interested in using non - potable water to irrigate 1,720 acres of land in the eastern part of the city. The non - potable system would be used to meet over 40 percent of the total irrigation demand for residential, industrial, commercial, and public uses. Boyle Engineering was hired to prepare a conceptual study of alternatives for delivering 2,400 acre -feet of non - potable irrigation water annually to the current and future sites. Boyle engineers are currently analyzing six options for delivering the non - potable water options: an infiltration gallery or direct diversion of Cache la Poudre River water, a well field, an existing canal system, an existing 27 -inch potable water pipeline, gravel pits, and a combination of the previous five alternatives. - 11 - 130VLE
