" 1 I <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 />[E.rample: If the average raw water demand during the previous summer was <br />10.8 million gallons per day (ILIGD), and the OWASA reservoir system currently <br />contained 2.8 billion gallons of water in storage, the total volume of stored water <br />woa~ld be equal to 2.8 billion/10.81~IGD = 2.i9 days of demand. This example <br />would not constitute a Stage 1 Water ShortageJ; <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 fuushed 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 1.6.5 = <br />1 S. 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 />1 S. 7 MGD =1 ~.1 MGD.J <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 />
