In an era of increased concern about limited water supplies, energy consumption, water quality and climate change, the pressure on water utilities to deliver greater efficiency and operational effectiveness is greater than ever for this energy-intensive industry.
According to the Environmental Protection Agency (EPA), water utilities across the United States and elsewhere in North America are saving substantial amounts of water through efficiency programs. These savings often translate into capital and operating savings, which allow systems to defer or avoid significant expenditures for water supply facilities and wastewater facilities. Drinking water systems can implement efficiency measures and still deliver an unchanged or improved level of service to consumers.
