About the Urban Watershed Assessment

As part of the Sewer System Improvement Program, the San Francisco Public Utilities Commission (SFPUC) is planning infrastructure improvements in each of San Francisco's eight distinct watersheds. The Urban Watershed Assessment is the watershed-based planning process SFPUC is using to help plan the City’s Sewer System Improvement Program (SSIP), a 20-year, multi-billion dollar project. These improvements will include both "grey" infrastructure such as pipes and tunnels, and "green" infrastructure such as rain gardens and permeable pavement to address such challenges as localized flooding, aging infrastructure, seismic safety and reliability, and water quality in the Bay and Ocean.

 Aging Infrastructure  Seismic Vulnerability  Climate Change Impacts

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 treatment facilities are seismically vulnerable.


Climate Change Impacts

The increasing intensity and frequency of storms can overwhelm our system and contribute to flooding.

Recent Past Events 

We want your input on neighborhood sewer system challenges and feedback on proposed improvement solutions! There will be many opportunities for public input through the adoption of the Urban Watershed Plan in 2015.

Planning Game Workshop – November

Thank you to everyone who attended our interactive workshop on Saturday, November 16, 2013 to help plan necessary upgrades to San Francisco’s combined sewer system. The workshop was a great success for the Urban Watershed Assessment and featured the interactive watershed planning game to generate ideas for green and grey infrastructure solutions for San Francisco’s Islais Creek, Sunnydale, and Yosemite watersheds. Thank you again! Your input will contribute to the SFPUC’s Urban Watershed Assessment and the next 20 years of sewer system upgrades through the Sewer System Improvement Program.
