FAQs: Frequently Asked Questions

Is it important to prevent backflow?

All water users benefit from an active, on-going cross connection control program that includes the installation of backflow preventer. Maintaining the quality and safety of our water is of the utmost importance to the City of Mount Shasta. California requires all public water systems to operate an on-going program to protect the public water supply from contamination from possible cross connections. The most effective method for the water utility to meet this requirement is to require customers to install a backflow preventer on the main supply line to their property or facility, thus protecting the community water system from any cross connections that may be present inside the customer’s plumbing system.

The need for cross-connection control exists in all types of premises, whether residential, commercial or industrial. Backflow prevention devices help protect the public safety by preventing potable water contamination in such critical areas as municipal water systems, food processing plants, medical and dental water supplies, and many industrial applications.
