washing, and waste disposal, and for on -farm livestock watering, excluding commercial livestock operations which use more than 10,000 gallons per day. Second Priority. Water uses involving consumption of less than 10,000 gallons per day. Third Priority. Agricultural irrigation and processing of agricultural products. Fourth Priority. Power production in excess of the use provided for in the contingency plan under first priority. Fifth Priority. Uses, other than agricultural irrigation, processing of agricultural products, and power production. Sixth Priority. Non - essential uses. These uses are defined by Minnesota Statutes 103G.291 as lawn sprinkling, vehicle washing, golf course and park irrigation, and other non- essential uses. Allocation procedures should distribute water equitably within each water use priority and customer category. Non - essential uses of water are the lowest use priority and will be the first water use subject to allocation restrictions. Quick responses to restrict non - essential uses of water during periods of limited supplies will help protect domestic and economic uses of water. Water used for human needs at hospitals, nursing homes, and similar types of facilities should be designated as high priority to be maintained in an emergency. Local water allocation will need to address water used for other human needs at other types of facilities such as hotels, office buildings, and manufacturing plants. Domestic use must have priority over economic needs. 7.7 TRIGGERS FOR IMPLEMENTING PLAN COMPONENTS An important part of reducing short -term demand is establishing triggers for implementing the various components of the plan. To establish triggers, the existing water sources were examined. The City is dependent on its wells as the water source to meet the water demand from its customers. The current average day demand is 87,900 gallons and - 4lte average peak day demand for the past eight years is approximately 2.3 times the current day demand, or 205,000 gallons. file 100,000 gallons of available storage capacity in the City's elevated storage tank can provide slightly more than a day of an average day demand and slightly less than a half day at peak day demand. Tower level is critical to maintain pressure in the distribution system. The most critical component of the Centerville system is the pumping capacity from its wells. For emergency conditions, the City should consider that the largest well pump is out of service. This is referred to as the firm capacity. Centerville's firm capacity is 550 gpm (0.675 MGD) with its largest well (650 gpm) out of service. Triggers for implementing plan components are based on firm capacity. CWP- 260A.080 7 -5 260-080 -25
