American Water (NYSE: AWK), the largest publicly traded U.S. water and wastewater utility company, today announced Suzanne Chiavari, Engineering Practice Leader, will speak on a webinar hosted by the Center for Climate and Energy Solutions (C2ES) on July 24 at 2:00 p.m. ET.
During the webinar, titled Innovation and Effective Stakeholder Engagement on Water and Energy Issues, Chiavari will describe American Water’s recent work using renewable energy technologies, and how the company has engaged community partners to establish greater integration across its resource management activities.
One example of this is American Water’s use of solar energy. American Water has installed over 3.1 megawatts of direct current of solar generating capacity at eleven facilities across three states (N.J., Ill. and Mo.). The first solar installation was a 500-kW facility constructed in N.J. in 2005 and today, that same expanded facility generates over 800,000 kilowatt-hours per year of clean energy and provides 20 percent of the peak usage power to run the water treatment plant. Other facilities include a floating 115-kW solar array on a reservoir at the Canoe Brook Water Treatment Plant in Milburn, N.J.; an 890-kW ground mounted facility in Mansfield N.J. that powers 50 percent of the well station at peak load, and the most recent addition of a 25-kW array in Brunswick, Mo.
American Water also patented NPXpress, a unique nitrogen and phosphorus removal process for wastewater treatment that offers reduced energy requirements and chemical consumption. It has reduced aeration energy use by up to 50 percent and supplemental carbon source by 100 percent at two full-scale wastewater treatment plants in Mapleton and Jefferson Peaks, N.J.Additionally, American Water has formed a partnership with ENBALA Power Networks. ENBALA’s innovative technology connects the demand-side assets of industrial and institutional electricity users to the Smart Grid to provide Grid Balance to electricity system operators. The technology manages the way electrical equipment – which in this case is American Water’s treatment plants and pumps – uses power without impacting the efficiency of its process or its operational costs.
