SR-08-12-2014-3ECity of City Council Report Santa Monica City Council Meeting: August 12, 2014 Agenda Item: 3 -E To: Mayor and City Council From: Dean Kubani, Sustainability Manager, Office of Sustainability and the Environment Subject: Technical Assistance for Energy Efficiency Improvements for the City's Water Production and Treatment Facilities Recommended Action Staff recommends that City Council: 1. Adopt the attached resolution authorizing the application for technical assistance, at no cost to the City, from the California Energy Commission to identify energy efficiency improvements in City water production and treatment facilities; and 2. Authorize the City Manager to execute all necessary documents to apply for and receive technical assistance from the California Energy Commission. Executive Summary The City has the opportunity to receive free technical assistance to identify energy efficiency improvements at its water production and treatment facilities to support the municipal emissions reduction target established in the 15x15 Climate Action Plan, the Sustainable City Plan, and the Sustainable Water Master Plan. The California Energy Commission offers technical assistance worth up to $20,000 in consulting services. The City would apply to receive these services to assist in improving energy efficiency at the water production and treatment facilities. Several options for retrofitting production and treatment facilities to improve energy efficiency and increase water recovery may exist, thus achieving the City's water self- sufficiency and greenhouse gas emissions reductions simultaneously. Background On September 20, 1994, (staff report not available online), Council adopted the first Sustainable City Program, including the initial iteration of the Sustainability City Plan (SCP). The SCP sets targets and goals across a variety of social, economic and environmental indicators. On February 11 2003 Council adopted updates to the SCP, adding a target to reduce greenhouse gas emissions from municipal operations by 30% below baseline levels by 2015. On February 26 2013, Council adopted the 15x15 Climate Action Plan, to reduce greenhouse gas emissions community -wide by 15% below baseline levels by 2015, with several actions directly relating to municipal operations. On March 8, 2011, Council committed the City to becoming water self- sufficient by the year 2020. Conservation and efficiency, combined with increased supply, will help the City realize this goal. The Charnock and Arcadia Water Facilities are critical to achieving water self- sufficiency, as they treat and distribute water to the City's 18,000 billed water customers. As more local groundwater is pumped, treated and distributed, energy usage has increased, highlighting the nexus between energy and water. In order to meet water self- sufficiency, the production from local groundwater supplied could increase by up to 50 %. Unless more energy- and water - efficient equipment and operations are implemented at new and existing facilities, energy use will also continue to rise. Therefore, technical engineering expertise in water treatment facilities is needed to assist staff in identifying energy efficiency opportunities. Discussion Through its Energy Partnership Program, the California Energy Commission provides up to $20,000 of consulting services for new construction and existing facilities. This technical assistance can be utilized to conduct energy audits and prepare feasibility studies. Even though most of the equipment at the water treatment facilities is relatively new, an audit would provide recommendations for new, more efficient equipment and operational procedures that were not available when the facilities were built. Potential measures identified for further investigation include more efficient volatile organic compound blowers, bubblers /diffusers, energy recovery and wastewater reduction from the reverse osmosis process, and improvements to the booster stations at the Charnock and Arcadia Water Facilities. Because this program has limited funds for technical assistance, primary consideration would be given to those that are committed to implementing the recommended projects. The application requires an adopted resolution from Council committing to implement the recommended measures identified by the consultants, provided . that the recommendations for energy efficiency meet the operational needs of the City. Funding will be sought to implement the adopted recommendations identified by the Energy Partnership Program. Financial Impacts & Budget Actions There is no immediate financial impact or budget action necessary as a result of the recommended action.
