Abstract: This report presents an application of a methodology for reducing the amount of energy used for pumping in treated water distribution systems. The methodology can be divided into three steps: (a.) field testing of pumps to ensure that they are performing to specifications, (b.) determining the best combination of pumps to achieve a given discharge, and (c.) determining the optimal discharges (or tank water levels). The methods presented in the report are applied to pumping stations serving the water distribution system for Washington, DC, and the vicinity. They indicate that energy savings of approximately 5 percent ($90,000 per year for the two pressure zones investigated) can be realized without adversely affecting service. The methods can be used in developing rough rules for pump operation or for real-time control of pumping.
