Alternate Water Source Systems

Alternate water sources are a critical component to management of our city's water supply. San Francisco Health Code Article 12C governs the collection, treatment, and reuse of rainwater, stormwater, graywater and other alternate water sources for toilet flushing, irrigation and other non-potable uses in commercial, multi-family, mixed-use, and multi-parcel developments.

 

The permit process is a collaboration among SFDPH Environmental Health Branch, the SFPUC and the San Francisco Department of Building Inspection Plumbing Inspection Division. Together these three agencies provide input and oversight on the design, construction, and operation of alternate water source systems. The permit process from project conceptualization to startup is summarized below. More details are described in the step-by-step guidebook available on the SFPUC website.

 

SFDPH's Rules and Regulations for Alternate Water Source Systems describe all requirements.
