Role in The Energy-Water Nexus

The water and wastewater treatment sectors account for as much as 3% of electricity use in the U.S. In the drinking water sector, pumping accounts for about 90% of energy use, whereas in wastewater treatment the majority of energy use is due to treatment processes. EPA’s ENERGY STAR partnership offers organizations a proven energy management strategy that helps measure current energy performance, set goals, track savings, and reward improvements. To extend this management strategy to the water and wastewater sectors, LBNL will help EPA design an Energy Performance Rating System (EPRS) for each sector that is normalized for the appropriate variables such as climate, plant/system characteristics, and regional differences. The EPRS will facilitate internal and external performance comparisons within and between water and wastewater utilities.
