Planning for San Francisco's Sewer Needs
As part of the Sewer System Improvement Program (SSIP), the SFPUC is undertaking the Urban Watershed Assessment (UWA), a long-term planning process to develop solutions in each urban watershed to address the City’s sewer system challenges.
SF's Sewer System Challenges
 |
 |
 |
|
Aging Infrastructure
Over 80% of our pipes are over 100 years old and the system gets overwhelmed during heavy rains.
|
Seismic Vulnerability
Our sewer system was not built to withstand a major earthquake. Our sewer pipes and three treatment facilities are seismically vulnerable.
|
Climate Change Impacts
The increasing intensity and frequency of storms can overwhelm our system and contribute to flooding.
|
To ensure the City has a reliable and resilient sewer system, the Urban Watershed Assessment's proposed solutions will include both green (e.g. rain gardens and permeable pavement) and grey (e.g. pipes and tunnels) infrastructure. The SFPUC will use an innovative Triple Bottom Line analysis tool to assess each solution's community, environmental, and economic benefits.
Dedicated to Public Participation
An expert analysis is being completed for each of the City's eight urban watersheds to highlight their unique characteristics.
Public input is being gathered from the community in the Bayside watersheds (from Fisherman's Wharf to the Excelsior neighborhood) through the Summer 2013. (Click here for the UWA Timeline.) We want your input on neighborhood sewer system challenges and feedback on proposed improvement solutions!
Join us at one of the upcoming events!
Thank you for those who joined us on June 1st for an interactive workshop to help us plan for healthy urban watersheds! Your input will contribute to the Urban Watershed Assessment plan for the next 20 years of sewer system upgrades.
If you missed the workshop, check out these materials to get a head start on the next one!
