The City of San Diego’s Department of Water Utilities offers water use calculators for household and landscape use. There are also rebate programs available for micro irrigation, turf removal, and rain barrels. The City of San Diego is also a member of the San Diego County Water Authority (SDCWA), which has been partnering with SDG&E for more than twenty years on administering water efficiency programs, such as low-flow showerheads, small business water efficiency equipment, leak loss detection, and education and outreach.

The City of San Diego’s Climate Action Plan has several water savings targets and long-term strategies to reach those targets. One target is to reduce daily per capita water consumption by 4 gallons by 2020 and 9 gallons by 2035 below 2010 levels. The core strategy is to implement an Outdoor Landscaping Ordinance that requires use of weather-based irrigation controllers. Supporting strategies to meet these targets are to record the annual volume percentage of recycled water used and planned to be introduced through 2035 and pursue additional financial resources and incentives for implementing energy and water efficiency measures identified by the conservation and ordinances, and to promote the expansion of greywater systems.

The City is also launching Pure Water San Diego, a phased, multi-year program that will provide one-third of San Diego's water supply locally by 2035. The Pure Water Program will use proven water purification technology to clean recycled water to produce safe, high-quality drinking water. The program offers a cost-effective investment for San Diego's water needs and will provide a reliable, sustainable water supply.

Water Plant Efficiency and Self-Generation

The City of San Diego’s Climate Action Plan encompasses both local water and wastewater utilities’ operations and include targets to reduce energy consumption at municipal facilities by 15% by 2020 and an additional 25% by 2035 below 2010 levels. Strategies to reach these targets include implementing a Smart Energy Management & Monitoring System for facilities to monitor and track energy consumption and using those results to identify opportunities for great efficiency and demand response along with pursuing LEED for Existing Buildings: Operation and Maintenance Certification for municipal facilities.

Since 2000, the Public Utilities Department has maintained a California Energy Commission-trained Energy Audit Team. Nearly all of the Department's major facilities have energy audit reports. The Department has invested an average of $400,000 per year in energy efficiency projects which have upgraded almost all of its emergency generators, department-owned administration buildings, as well as many of its largest pump stations and wastewater treatment plants. Projects have included lighting re-lamping and control, air conditioning system improvements, and process improvements.

The City of San Diego’s Wastewater Branch has a multiple self-generating facilities and projects. The City also has a goal to capture 98% wastewater treatment gases by 2035. At the Point Loma Wastewater Treatment Plant (PLWWTP), methane gas is captured to fuel two generators for a total capacity of 4.57 MW. The system also produces heat, which is used to heat the plant’s digesters. Methane capture is also utilized on two other sites: the Metro Biosolids Center (MBC) and the North City Water Reclamation Plant (NCWRP). The MBC has two privatized cogeneration total capacity of 9.6 MW, and the NCWRP has two City-owned power generation plants total capacity of 5.39 MW. The PLWWTP has an adjacent 1.35 MW hydroelectric plant that captures the energy of the treated wastewater discharge as it flows down a 90 foot-drop from the plant to the ocean outfall. At the Metro Operation Complex, Department has two solar systems for a total capacity of 0.430 MW. The Department’s Water Branch has multiple solar generation facilities. The Alvarado Water Treatment Plant has 0.95 MW privatized solar system.
