DRAFT Sewer System Upgrades

Keeping San Francisco Healthy

Water and sewer systems are vital to public health. Everyone needs clean water and functioning plumbing. San Francisco's sewer system protects public health and the environment by safely collecting and treating wastewater and stormwater 24/7/365. Many parts of our sewer system are over 100 years old. We are making upgrades now so our sewer system continue to work safely and reliably for generations to come.

Clean Water and Reliable Plumbing are Essential to Public Health

San Francisco's sewer system is old. Some parts were built before modern plumbing or seismic standards existed. Delaying these repairs now will only make these upgrades more expensive later.
