Following an earthquake, the San Francisco Emergency Firefighting Water System is vital for protecting against the loss of life, as well as the loss of homes and businesses by providing an additional layer of fire protection. The system is also used throughout the year for the suppression of multiple-alarm fires. The system delivers water at high pressure and includes two pump stations, two storage tanks, one reservoir, and approximately 135 miles of pipes. The system includes 52 suction connections along the northeastern waterfront, which allow fire engines to pump water from San Francisco

We’re committed to being a good neighbor in the communities where we operate and provide services. Our Agency offers 15-25 Project Learning Grants (PLGs) for $15,000-$25,000 to local nonprofits to fund projects providing youth and young adults from underserved communities with educational and employment programs. These grants support projects that increase the understanding of water, power and sewer services while fostering the next generation of environmental stewards. As a result, community organizations and local nonprofits are able to provide 600+ youth each year with summer and after

California Public Utilities Code (PUC) section 8387 requires that the SFPUC maintain and operate its electrical lines and equipment “in a manner that will minimize the risk of catastrophic wildfire posed by those electrical lines and equipment.” Additionally, PUC § 8387 requires that the SFPUC “shall, before January 1, 2020, and annually thereafter, prepare a wildfire mitigation plan.” The objectives of the SFPUC’s Wildfire Mitigation Plan (WMP) is to: Reduce the risk of potential wildfire-causing ignitions associated with the SFPUC’s electrical infrastructure. Implement a WMP that embraces

From Sludge to Biosolids Let's learn how we treat solids extracted during the primary and secondary treatment processes. In the beginning, the extracted solid material is called "sludge." The treatment process transforms sludge into biosolids, a recycled product that can be used as a fertilizer replacement. San Francisco produces approximately 65,000 wet tons of biosolids every year (1 ton = 2000 pounds). Step One: Thickening Sludge separated from wastewater during primary and secondary treatment still contains a lot of water. Gravity belt thickeners are used to optimize the moisture level of

Where you live determines which treatment plant your wastewater is cleaned. (Where does my sewage get treated?) There are two 24-hour treatment plants that operate 365 days a year. We also have a third facility called a "wet-weather facility" that only operates during rain events. Wastewater treatment is separated into liquid and solids processing components. 2 Treatment Plants and 1 Wet-Weather Facility

Catch Basins and Storm Drains Stormwater enters the combined sewer system through roof drains on buildings or the thousands of catch basins along the street. Sanitary sewage flows from homes and businesses into sewer lateral pipes to sewer mains and through a network of over 1,000 pipes. We own and operate about 1,900 miles of sewer mains and laterals right under the street. End to end, it would stretch from here to Colorado (and back) and over 300 miles are more than 100 years old! A few areas in San Francisco are serviced by a separate sanitary sewer system, which is designed to transport

San Francisco is the only coastal city in California with a combined sewer system that collects and treats both wastewater and stormwater in the same network of pipes. Water flows through most of the sewers using gravity. Our hilly geography comes in handy reducing the energy and maintenance costs associated with mechanical pumping. Stormwater enters the combined sewer system through building roof drains or the catch basins along the street and gets treated at our plants just like the wastewater that goes down your drain. One of the City’s challenges is that the watershed area is mostly paved

Every time you flush the toilet, take a shower, brush your teeth, do your laundry, or wash the dishes; this wastewater is collected and treated by the City's sewer system. Our sewer system collects and treats sewage from homes and businesses, stormwater (rainwater) and street runoff into the drains. This is our City’s lifeline protecting public health and environmental quality. Nearly one million residents, businesses and visitors rely on our sewer system every day. We own and operate about 1,900 miles of sewer mains and laterals right under the street. End to end, it would stretch from here
