customer demand, as determined on the basis of average raw water usage during <br /> the months of May through September of the previous calendar year; <br /> [Example: If the average raw water demand during the previous summer was <br /> 10.8 million gallons per day (MGD), and the OWASA reservoir system currently <br /> contained 2.8 billion gallons of water in storagd, the total volume of stored water <br /> would be equal to 2.8 billion/10.8 MGD =259 days of demand. This example <br /> would not constitute a Stage I Water Shortage]; <br /> or <br /> b) It is otherwise determined that the Cane Creek/University Lake/Stone Quarry <br /> system is unable or unlikely to continue meeting the demands of OWASA's <br /> customers without a substantial reduction in consumption; <br /> or <br /> c) The customer demand for water averaged over three successive days, as measured <br /> by OWASA production records, exceeds 90 percent of the target three-day peak <br /> limit established for that year. Target limits may be established each April by <br /> multiplying average finished water demands for the previous 12 months by a <br /> peaking factor of 1.65, or may be established by other production constraints— <br /> such as water treatment capacity-determined by OWASA's Executive Director. <br /> [Example: If average finished water demand for the previous 12 months was 9.5 <br /> MGD, then the target limit for the coming summer would be 9.5 MGD x 1.65 = <br /> 15.7 MGD. A water shortage would be declared if the demand, when averaged <br /> over three successive days, exceeded 90 percent of that target level; e.g., 0.90 x <br /> 15.7 MGD = 1 4.1 MGD.] <br /> 2. Any of the following conditions, as determined by OWASA's Executive Director, <br /> shall constitute a Stage II Water Shortage: <br /> a) The total volume of water stored in OWASA's Cane Creek/University Lake/Stone <br /> Quarry reservoir system is equal to or less than 75 summer days of OWASA <br /> customer demand, as determined on the basis of average raw water usage during <br /> the months of May through September of the previous calendar year; <br /> or <br /> b) It is otherwise determined that the Cane Creek/University Lake/Stone Quarry <br /> system is unable or unlikely to continue meeting the demands of OWASA's <br /> customers without a substantial reduction in consumption; <br /> or <br /> 2 <br />
