Plant Tours - SF Public Utilities Commission (SFPUC)

Have you ever wondered what happens to the dirty water from your shower, laundry and toilet after it goes down the drain? What about the runoff from lawns and gardens, and rainwater and car washing? 

Find out by taking a free tour of one of San Francisco's Wastewater Treatment Plants. You'll learn about the history of wastewater treatment in San Francisco and plans to upgrade our aging sewer system, tips on preventing pollution of our Bay and Ocean, and best of all, you'll go behind the scenes to see (and smell!) how this vital infrastructure works.
