Regulations and Studies on Recycled Water Use
California has been safely using treated recycled water since 1929, with no
health-related incidents. Residents, businesses and farmers are using recycled
water for irrigation and for growing at least 20 varieties of food crops,
including lettuce and celery. California residents have demonstrated confidence
in recycled water, in part, because it is heavily regulated by the State
Department of Health Services (DHS) and the nine California Regional Water
Quality Control Boards. These agencies create and enforce some of the strictest
water quality regulations in the world - they govern production, transport and
use, as well as the prevention of runoff and cross connections between potable
and recycled water systems.
The linchpin of these regulations is DHS Title 22 which is enforced by the
regional Water Quality Control Board. Above are links to DHS and the many
regulations safeguarding the use of recycled water in California.
