The relationship between water and energy is a close one. Water requires a tremendous amount of energy to move from a reservoir or well, through the treatment process, and out into a distribution system. In addition, energy is required to process wastewater and recycle or discharge it. The energy required to operate the water and wastewater system is often called embedded energy. Despite this strong connection, the energy intensity of water and wastewater systems is relatively undocumented. There are few data sources and reports analyzing the energy required to move and treat water, and the data generally are not publicly available. ACEEE has been working to gain a better understanding of the energy embedded in water in order to help water utilities reduce costs, improve energy efficiency, and quantify the avoided energy and pollution savings that accrue as a result of water conservation programs. As part of an ongoing effort to advance the understanding of the water-energy nexus and bring attention to possible opportunities, the National Association of Water Companies (NAWC) and the American Council for an Energy-Efficient Economy (ACEEE) collaborated on a new research project to gather primary information on the amount of energy required to treat and distribute water. ACEEE and NAWC jointly produced a survey for NAWC's member companies related to their energy use and water processing. NAWC has over 100 member water and wastewater companies of varying sizes throughout the United States.
