Wastewater Treatment Plant Tours

Oceanside Treatment Plant Tour Group PhotoHave 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.

Tour Specifics

  • Tours take approximately two hours to complete.
  • Attendees over 18 years of age must present a valid photo ID on the day of the tour.
  • Tours involve quite a bit of walking, stair climbing, and going underground in tight hallways; we can modify the route to accommodate wheelchairs, canes and walkers. We have no facilities for, and cannot accommodate, young children, infants, or strollers.
  • Treatment plants are functioning industrial sites that operate 24 hours a day, seven days a week. Hard hats are provided and must be worn at all times.

Dress Code

Sturdy closed shoes and socks, long pants and long-sleeved shirts are required for your safety and comfort. NO flip-flops, sandals, clogs, open toed shoes, shorts, skirts, or tank tops.

Those not wearing the appropriate attire may be turned away from taking the tour.
