V. SUPPLY The two sources of potable water will be Well No.3 and water delivered from the Water District. Well No.3 is a well completed into the Laramie-Fox Hills Aquifer. The well has never been permitted with the State Engineer's Office. A well permit is currently being prepared and will be submitted along with a groundwater analysis establishing that the aquifer at Nunn is nontributary . Pumping tests indicate that Well No.3 can sustain a pumping rate of 10 gpm. The well currently is pumped at 16-17 gpm and is run daily on a clock. The water system will be programed so that the use of Well No.3 will be maximized. If Well No.3 is maximized it should produce approximately 14,400 gallons per day which equates to 16.1 acre-feet annually. During the winter months Well No.3 will provide about 50% of the Town's supply and about 10% to 20% of the supply during the summer months. Based on projected demands of 63.5 acre-feet per year, the amount of water delivered from the District will be 47.4 acre-feet (15.4 million gallons). Based on these fIgures, 75% of the Town's water supply will be delivered from the District. In the feasibility study it was assumed the Town would obtain 70% of the supply from the District. The amount of water from the District is slightly higher because the high nitrate wells, Well Nos. I and 2, will not be used for the potable supply. The wells will be used solely for park irrigation and other non-potabie uses. The decision to not use Well Nos. I and 2 for the potable supply was due to the high nitrate levels produced from the wells and the location of the wells. The wells are completed in Town in the shallow Spring Creek Alluvium. The Town's wastewater is handled by individual septic systems. There is concern regarding future development in Town and the potential impacts on the wells. VI. PROJECT COSTS There are two primary areas of project costs; the water line construction costs and the water rights purchase. Table No.2 itemizes the project costs. The construction costs are broken down into two categories, the construction that will be owned by the District and the construction within the Town limits which will be operated and maintained by the Town ofNunn. The District provided a cost estimate for the water line extension to County Road 98 and the Nunn Booster Station which is listed on Table No.3. This portion of the construction costs is estimated at $222,500. The primary components of the construction costs in the Town limits are the water line extension to the existing Nunn distribution system and the installation of the required controls, telemetry and valving necessary to operate the system with the new confIguration. The in-Town construction costs have been estimated at $77,740. The total projected construction costs for the project is $300,240. 4
