The total annual energy cost for water supply in the city of Phoenix for the fiscal year 1980-81 was $7 million. Of this, energy costs for water treatment for the four water treatment plants serving the city was over 1 Million dollars. The study and research performed under this grant focuses on the energy cost saving opportunities in water treatment. Elements of major energy consuming functions in water treatment include electric motor-driven raw water pumps and treated water booster pumps, and electrical energy consumption from lighting, heating, ventilation, air conditioning and power driven process equipment. The objective of this project was to study the process and equipment used in water treatment, exclusive of booster pumping, and to identify cost saving alternatives. Both the analytical approaches as well as results are transferable to other urban areas. The research plan included the identification and analysis of existing water treatment methods and equipment for possible energy savings. It also included energy audits of building heating, ventilating and air-conditioning (HVAC) and lighting systems to identify energy conservation measures (ECM's). 8 figs., 20 tabs.
