The regulations of the California Department of Public Health, Title 17 of the California Administrative Code, Sections 7583 through 7605, require the LADWP to develop and implement a comprehensive Backflow Prevention Program to protect the public water supply from contamination or pollution. The administrative and operating elements of this program are to be set forth in the LADWP's Rules and Regulations.
LADWP has the responsibility of protecting the public water system from contamination caused by the backflow of contaminants through the water service connection. If in the judgment of the LADWP, or the City of Los Angeles Department of Building and Safety acting as its authorized representative, an approved backflow prevention assembly is required, the LADWP or its authorized representative shall give notice to the consumer to install the approved assembly at the service connection to the premises. The consumer shall immediately install the approved assembly or assemblies at his own expense. Failure, refusal, or inability on the part of the consumer to install, test, and maintain the approved assembly or assemblies shall constitute grounds for disconnecting water service to the premises. Water service will not be restored until such conditions or defects are corrected to the satisfaction of the LADWP.
Consumers are strongly encouraged to contact the LADWP Backflow Prevention Group at (213) 367-3471 to verify that the backflow prevention device they plan to install is an approved assembly, before installing it.
