Tour the Regional Wastewater Treatment Facility

Touring our facility is a memorable, eye-opening experience. You'll learn how 10 million gallons of wastewater is treated daily—either purified and recycled to irrigate green spaces or safely cleaned and pumped into San Francisco Bay.

  • See your utility dollars in action.
  • Find out about rewarding careers in the water industry.
  • Gain new appreciation for the infrastructure we count on every time we flush.
