The City of Cortez s drinking water system supplies the City s residents and several adjacent areas outside of the City s municipal boundaries, including Montezuma Water District No. 1 and the Ute Mountain Ute Tribe. The drinking water supplied to Cortez, MCWD#1, and the Ute Mountain Ute Tribe is their exclusive source of drinking water. The water system is operated by the Public Works Department Director is Philip Johnson; Water Treatment Plant Superintendent is Richard Landreth. The City s water system consists of raw water drawn from McPhee Reservoir, followed by a small water storage reservoir, water treatment plant, finished water storage tanks, a distribution system, and associated administrative offices. The treatment plant provides a series of treatment processes, including coagulation, flocculation, sedimentation, multimedia granular filtration, submerged membrane microfiltration, and chlorine disinfection. j:\pwadmin\engineering\2018 projects\eng services\rfp - scada waterplant upgrade\2018 rfp wtp plc and scada upgrades.doc Page 4 of 5

5 Adjacent to the treatment plant is a raw water storage pond (the upper pond) and a small backwash pond (the lower ponds). Water flows from the upper raw water storage pond to the treatment plant by gravity. Backwash water from the treatment plant flows by gravity into the lower backwash ponds, and is then returned via pumping to the upper raw water storage pond. The City s drinking water system was originally constructed in 1960 and has undergone several subsequent upgrades. The treatment system was upgraded in 2006 to include submerged microfiltration treatment, complementing the existing treatment processes. In early 2010, additional upgrades were made to improve the filter backwash system. The recent upgrades have improved system performance and reliability, and helped ensure compliance with increasingly stringent public health and environmental regulations. Finished water is stored in three above ground storage tanks that pressurize the distribution system and ensure adequate water is available during high demand periods. Each storage tank has a capacity of two million gallons (MG), and all are located near the drinking water treatment plant. Two tanks are located at a higher elevation than the lower tank. The upper two tanks provide water to the Ute Mountain Ute Tribe through a dedicated pipeline and to the lower tank. The lower tank provides water to the City of Cortez and Montezuma Water District No. 1. The drinking water supply for the City of Cortez is from the Dolores River and McPhee Reservoir, the second largest reservoir within Colorado. The Dolores River is a tributary of the Colorado River, approximately 250 miles long, and flows through Colorado and Utah. It starts in southwestern Colorado near Dolores Peak and Mount Wilson in the San Miguel Mountains. It flows southwest, past the Town of Dolores, where it turns, flowing north and northwest. It then flows through the Dolores River Canyon, cuts across Paradox Valley before receiving the San Miguel River in Montrose County and crossing into Utah, where it joins the Colorado River in Grand County. McPhee Reservoir was created via the construction of McPhee Dam on the Dolores River, and is part of the Dolores Project. The Dolores Project is managed by the Dolores Water Conservancy District (DWCD), and consists of a system of canals, tunnels, and laterals that convey water from McPhee Reservoir to a number of nearby agricultural, residential, commercial, and governmental users. McPhee Reservoir has a maximum storage capacity of 381,000 acre feet of water. j:\pwadmin\engineering\2018 projects\eng services\rfp - scada waterplant upgrade\2018 rfp wtp plc and scada upgrades.doc Page 5 of 5
