The Consolidated Mutual Water Company (Consolidated) backflow program is designed to protect Consolidated’s water system from contamination or pollution caused by backflow from an owner’s internal distribution system or private water system.
Consolidated’s backflow program also monitors testing of backflow devices, which will systematically prevent the contamination or pollution of Consolidated’s water system. All commercial properties and multi-family residential properties of 3 units or more, per water meter, are required to have a Backflow Inspection conducted. If the installation of a backflow preventer device is required, it is the property owner’s responsibility to have a Consolidated representative present during the installation of a University of Southern California (USC) approved backflow prevention device. The property owner is also responsible for having backflow devices tested every year after installation.
Be aware that Consolidated may require certified inspections at more frequent intervals. A backflow prevention device must be repaired or replaced within 10 days whenever a device fails testing, at the owner’s expense.
Any person who violates any provisions of this program is subject to termination of water service until the violation is corrected.
Contractors – be advised you are obligated to have adequate backflow prevention during construction, or other projects while utilizing Company water lines.
