Raw and finished water pumping typically consumes more than 70 percent of the energy at a surface water treatment plant. The Second Taxing District Water Department (STDWD) in Norwalk, Connecticut, realized that the annual energy costs at one of its pump stations could be reduced by 45 percent by making optimal use of a standby generator to power the pumps. This paper describes the four steps the STDWD used to decide whether to use commercial electricity or standby generators each month.
