Accomplishing OneWaterSF Adapting to Future Changes Expanding Recycled Water Impact: Examining Reuse Opportunities for Recycled Water in San Francisco Water is too precious a resource to use just once. Treated effluent from our water treatment and recovery plants offers a new water source for various purposes. The SFPUC has prepared a White Paper to review the evolution of water reuse in San Francisco and to assess future opportunities. Recycled water can be used for several non-potable uses, such as landscape irrigation of parks, toilet and urinal flushing, decorative fountains, soil compaction, and dust control. Additionally, purified water refers to drinking water produced from recycled water using the most advanced purification treatment processes available. The White Paper lays out the SFPUC’s planning strategy for current and near-term recycled water reuse projects in San Francisco and recognizes future challenges and opportunities for expanding non-potable and potable reuse to maximize the use of our water to meet existing and future needs. Getting Creative with Space San Francisco covers area less than 50 square miles, making space a premium. Ensuring that all the available space for the SFPUC is used to its full potential, the SFPUC has embarked on a concerted effort to co-locate solar panels on its water and wastewater properties and facilities. The most visible example of this is the solar array located above the Sunset Reservoir. The Sunset Reservoir Solar Array is San Francisco’s largest solar installation. With a generating capacity of up to 5 megawatts, the Sunset Solar Array was the largest urban municipal solar array in California when completed in 2010. In addition to Sunset Reservoir, the Southeast Plant and North Point Wet Weather facilities are both equipped with solar panels, and a solar photovoltaic system has been installed at the Tesla Light Water Treatment Facility; there are also plans to outfit the Oceanside Treatment Plant. Co-locating solar panels on existing infrastructure allows the SFPUC to provide energy benefits while also maximizing the use of space. 12 Co-Locating Solar Panels
