Faced with a declining customer base, increasing operations costs, and increasing capital and financing requirements, the Philadelphia Water Department devised a five‐year financial management plan to trim costs. One aspect of the plan included the control of energy expenses through the use of off‐peak pumping and elevated storage. One year after the program was implemented, the department achieved a savings of $2 million—in spite of increases in electrical rates.
