About the SSIP
Addressing the Challenges of Today and Tomorrow
Now more than ever, we are seeing the importance of upgrading and hardening our critical but aging sewer system in the face of extreme weather and climate change.
Smart Investments Now Save Money in the Long Run
The longer these upgrades are delayed, the more expensive they become. Making these investments today avoids more costly emergency repairs, potential regulatory fines, and greater impacts on our communities.
Protecting Public Health and the Environment
Our combined sewer system, which treats both sanitary sewage from homes and buildings and stormwater when it rains, is over 100 years old. Upgrades to modernize our system will ensure we can continue to protect public health and our environment for generations to come. Our vision is to evolve from pollution treatment to resource recovery and reuse.
Preparing for the Next Big Earthquake
In San Francisco, it’s not a matter of it, it is a matter of when our next big earthquake will strike. New facilities are being built to modern seismic standards to ensure we can operate within 72 hours of a major seismic event.
Improving Stormwater Management and Expanding Green Infrastructure
Citywide we are building innovative green infrastructure projects that use sustainable methods to help slow down or reduce the amount of stormwater going into our sewer system during rainstorms, while also providing more public open spaces and beautified neighborhoods. Our goal is to sustainable manage over 1 billion gallons of stormwater annually by 2050 and we are well on our way.
Investing in at a Sustainable and Affordable Pace
As a ratepayer funded utility, rather than investor owned like PG&E, we must balance the need to invest in our aging system with the cost to our ratepayers. Ongoing condition assessments allow us to prioritize our investments, while low-interest loans from state and federal agencies will save over $1 billion long-term.

Panhandle and Inner Sunset Large Sewer Rehabilitation Project
As part of the Sewer System Improvement Program investments, the Panhandle and Inner Sunset Large Sewer Rehabilitation Project will rehabilitate the existing 100+ year old sewer mains located under several streets located along the Panhandle and Inner Sunset.
- Expected Completion Date: Spring 2024
Lower Alemany Area Stormwater Improvements Project
As part of the Sewer System Improvement Program (SSIP), the Lower Alemany Area Rainwater Improvements Project will improve stormwater management and reduce the risk of flooding near the Alemany Farmer’s Market/Interstate 280 Highway interchange and in the lower Alemany neighborhood.
- Expected Completion Date: Spring 2028
