Environmental Health Policy Resources

In the face of rapidly changing hydrology resulting from climate change and other factors, environmental health professionals are increasingly confronting the need to facilitate and support water conservation, reuse and the development of local supplies. Below is a set of model policies and helpful resources to support environmental health in creating an enabling policy environment for decentralized water capture and reuse.

Onsite Water Reuse

Sample Policies and Programs

  • San Francisco Recycled Water Ordinance for new building construction and subdivisions or major alterations
  • San Francisco Non-potable Water Ordinance, allowing for the collection, treatment, and use of alternate water sources for non-potable applications (including water shared by two or more buildings), part of the city’s Non-potable Water Program, whose website includes grant assistance information, instructions for applicants, and a wealth of resources. Beginning November 1, 2015, all new buildings of 250,000 square feet or more of gross floor area, located within the boundaries of San Francisco's designated recycled water use area, must install non-potable water reuse systems to treat and reuse available alternate water sources for toilet and urinal flushing and irrigation. This requirement expands to the entire city the following year, on November 1, 2016.
