Cross Connection Control Program

The District's Cross Connection Control Program is mandated by the California Department of Public Health (CDPH), under Title 17 of the California Administrative Code of Regulation. It is an extensive effort to protect the public water system from potential sources of contamination that may exist within customers' plumbing systems and equipment on site.

Backflow prevention devices properly installed at the water meter helps eliminate the potential for contaminated water to flow back into the public drinking water system by way of "cross connection" and "backflow". The installation of these devices may be required after an inspection by a Cross Connection Control Specialist. The backflow prevention devices are required to be tested upon installation and on an annual basis as customers are notified by Monte Vista Water District.

This program and its records are inspected by the CDPH on an annual basis. Incidental reports are required to be submitted, as well.

For additional information please contact our Backflow/Cross Connection Department at (909) 624-0035 extension 175.
