c) If the customer demand for water averaged over three successive days, as measured by OWASA production records, exceeds 97 percent of the target three- day peak limit established for that year. Target limits may be established each April by multiplying average finished water demands for the previous 12 months by a peaking factor of 1.65, or may be established by other production constraints —such as water treatment capacity—determined-by OWASA's Executive Director. [Example: If average finished water demand for the previous 12 months was 9.5 A,IGD, then the target limit for the coming summer would be 9.5 AIGD x 1.65 = 15.7 MGD. A water shortage would be declared if the demand, when averaged over three successive days, exceeded 97 percent of that target level; e.g., 0.97x 15.7 MGD = 15.2 NIGD.] 3. Any other circumstances, including service losses caused by equipment failure, human error,weather, or other natural disaster,which constrain OWASA's water production capacity to less than the current level of customer demand, may constitute a Water Supply Emergency, as determined by OWASA's Executive Director. Section IV.
