Wastewater reuse has the potential to meet part <br />of the region's water supply needs. Investing <br />strategically to further the effectiveness of the <br />region's program for nonpoint-source pollution <br />prevention and control may also provide better <br />value for the region than investing to meet more <br />stringent wastewater discharge limits. <br />In addition, the MCES inflow and infiltration <br />(1/1) initiatives may be viewed as contributing <br />to water sustainability by limiting the amount <br />of clear water that enters the sanitary sewer <br />(and then lost to the region) and minimizing the <br />risks of water pollution from spills and outflow <br />from cracks. Funding to prevent 1/1 into regional <br />pipes is part of the rehabilitation work in the CIP. <br />Funding for 1/1 prevention in the local <br />community sewer pipes is a municipal <br />responsibility, although MCES does provide a <br />grant program. Property owners are <br />responsible for preventing 1/1 originating from <br />their property, although MCES and cities have <br />provided small grant programs. <br />Energy and Emissions. MCES remains on <br />track to meet its 25% purchased -energy <br />reduction goal by 2015 (base year 2006). Fully <br />attaining this goal will result in savings of over <br />$5 million annually, beginning in 2016. <br />In addition to generating energy from <br />processing biosolids, MCES has been and <br />continues to implement energy conservation by <br />selecting the appropriate type of wastewater <br />treatment and process, optimizing performance, <br />installing higher -efficiency equipment (motors, <br />pumps) and lighting, and reducing <br />building -energy use. MCES is also pursuing <br />the purchase of energy from solar -power <br />generation facilities. Energy conservation <br />and renewable -energy generation by MCES <br />contribute to reducing its purchased energy <br />as well as lowering greenhouse and other air <br />emissions. The Council has tracked and <br />reported annual emissions using the Climate <br />Registry protocols since 2007. <br />Waste. The wastewater system plan continues <br />to support the use of wastewater treatment <br />biosolids for energy generation for in -plant uses. <br />The Metropolitan Plant uses thermal processing <br />that reduces the biosolids to a small volume of <br />inert ash, while recovering energy that is <br />converted to electricity and steam for plant <br />usage. Moreover, MCES is studying the <br />beneficial use of ash for its value as a <br />phosphorus fertilizer. The Blue Lake and Empire <br />plants use anaerobic digestion to reduce <br />biosolids volume prior to its agricultural use <br />and to produce biogas (methane) for in -plant <br />uses. <br />B-6 <br />
