A master plan is a long-term planning document that provides strategies and policies for the future.  The City's last sewer system master plan occurred in 1970s and upgraded the system to meet new regulatory requirements. 

Today, San Francisco’s sewer system has operated well, but aging infrastructure, funding constraints, deferred maintenance, and a vision for a more sustainable system highlight the need for the current master plan. 

The S.F. Sewer System Master Plan aims to:

- Develop a long-term vision and strategy for the management of the City’s wastewater and stormwater;

- Provide a detailed capital planning roadmap for improvements needed;

- Estimate the funds to implement these improvements;

- Address specific challenges facing the system; and

- Maximize system reliability and flexibility
