Drinking water and wastewater systems are typically the largest energy consumers for communities, accounting for 25 to 40 percent of a municipality’s total energy bill.i Public water systems using surface water supplies use 1,407 to 1,483 kWh/ MG, depending on plant size, with approximately 80 to 85 percent of electricity consumption used for pumping treated water to the distribution system.ii Public water systems using ground water typically have a higher average energy use than surface water systems (about 1,800 kWh/MG), primarily due to energy demands for raw water pumping from aquifers.iii 12 • Second Quarter 2011
