The PureWaterSF project is a research project that explores how we can treat and reliably produce purified water on a small (building) scale using wastewater generated onsite. For this project, the SFPUC will be taking approximately 80% of the recycled water currently produced by the constructed wetland treatment system called the Living Machine™ at the SFPUC headquarters. The PureWaterSF process will further purify this water, bringing it to a level that is expected to meet or exceed drinking water standards. Data from this process will be collected and analyzed, and the water produced will

Welcome to the Discover Your Watershed Mapping Project of San Francisco Every person lives in a watershed. A watershed is an area of land from which all stormwater drain to a shared body of water. In San Francisco, we have eight distinct urban watersheds, three on the Westside where stormwater flows towards the Pacific Ocean, and five on the Bayside where stormwater flows towards the San Francisco Bay. This project is intended to help foster a connection between you and your watershed, a natural resource worth exploring. Click on the map to explore the past, present and future of our

Learn how our Biosolids program recycles nutrients from wastewater into a high quality fertilizer that helps reduce water use, pulls carbon dioxide out of the atmosphere, and improves California’s farm soils.

What is green infrastructure? We partner with plants and soil to slow down and clean stormwater. Green infrastructure takes advantage of the natural processes of soils and plants to slow down and filter stormwater in an effort to keep it from exceeding the capacity of our sewer system. Examples of Green Infrastructure

We protect our beautiful San Francisco beaches. We love this beautiful city and we live, work and play here, too. We all want clean beaches, and we take seriously our responsibility to protect and monitor our city’s shorelines. We partner with the SF Department of Public Health to collect water samples from beaches in SF every week, year round, and test them for bacteria levels to ensure they meet state standards for water recreation. We share our methods and publish our findings on a public map. See our real-time map of San Francisco Beach Water Quality Get more details on how we monitor our
