Gypsum Loan Feasibility Outline CWCB Water Project Loan Program Page 9 of 33 rights owned and leased by Gypsum. In addition, Gypsum is contractually required to provide up to 100 acre-feet of irrigation water in LEDE Reservoir for a local ranch that supplements the irrigation of 200 additiona.l acres under the H.O.R. ditch. The Town of Gypsum produces and stores its own drinking water. Gypsum has 2,038 water service taps. Drinking water is obtained from Mosher Creek and Gypsum Creek; both supply the entire Town with drinking water. Because the Mosher Springs diversion produces very high quality water, there are very few chemicals needed to treat this water supply. There are several large water storage tanks located throughout Town to ensure that Gypsum residents will always have a good supply of potable water. i. Mosher Water Treatment Plant & Dog House The Mosher Water Treatment Plant is located south of Town on Gypsum Creek. The water treatment plant is gravity fed from the Mosher Spring and Gypsum Creek. The Mosher Spring line delivers spring water from the source to a mixing facility located on Gypsum Creek. This facility is called the Town of Gypsum Water System Dog House. At the Dog House, the water can be blended with Gypsum Creek water or diverted straight to the Mosher Water Treatment Plant via an eighteen-inch ductile iron pipe water line, depending on the Town's water demand. The water treatment plant primarily uses Mosher Spring water to feed the plant. The Mosher Water Treatment Plant utilizes chemical feed, coagulation and flocculation, tube settlers and mixed media gravity filter technology with chlorination for final disinfection. The Mosher Water Treatment Plant utilizes three parallel individual water treatment trains for treatment. ii. Water Stora~e Tanks The finished water is then stored in the Mosher water storage tank adjacent to the treatment building. The Mosher water storage tank is a two million gallon storage tank. This storage tank feeds the upper pressure zone via gravity and distributes water to the Town's middle and lower pressure zones that include four one- million-gallon storage tanks and one two-hundred-fifty-thousand gallon storage tank. The Town currently has a total of 6.25 million gallons of storage facilities, which are adequate for the foreseeable future. iii. Nor~aard Water Treatment Plant The Norgaard Water Treatment Plant is located along Gypsum Creek in the middle of Town. The Norgaard Water Treatment Plant requires pumping to divert and deliver water. The raw untreated water is diverted from Gypsum Creek downstream of Cotton Ranch Golf Course on Gypsum Creek and is pumped up to the Norgaard plant for treatment. The plant has two trains used for water treatment. The first train at the Norgaard Water Treatment Plant utilizes chemical feed, coagulation and flocculation, tube settlers and mixed media gravity filter technology with chlorination for final disinfection. The second train utilizes
