Recycled Water


The Department of Environmental Health and Quality (DEHQ) regulates the use of recycled water through a delegation agreement with the State Department of Public Health.  The purpose is to protect the public from health risks associated with cross-connections of recycled water and drinking water supplies, as well as to prevent health risks from direct contact with recycled water.  

Land and Water Quality Division staff review recycled water use plans, and conduct site inspections to ensure drinking water supplies are not contaminated with recycled water.  Staff also monitor spray irrigation sites to ensure the recycled water irrigation does not present a risk to the public.  Recycled water sites must also pass an initial cross-connection control shut down test and every four years thereafter.  This can be coordinated with the water district supplying the recycled water.
