The Safe Drinking Water Act amendments of 1986 states that the water purveyor has the primary responsibility for preventing water from unapproved sources, or any other substance, from entering the public water system.
The purpose of the backflow program and devices is to provide a minimum standard for the protection of the public water supply. Protecting the public potable water system at the service connection is done by containing within the consumers premises the potential or actual pollution or contamination of the main water system which may result from backflow or cross-connection.
The County Environmental Management Department (EMD) coordinates the program for the City of Galt, as they do for many of the water purveyors in Sacramento County. EMD sends the letters to customers reminding the customer of testing or notifying customers that there water will be shut off if the backflow devices are not tested.
Backflow devices are not required on residential homes. They are required on businesses, irrigation, and processing operations that pose a threat of backflow or cross connection to the public water system. There are four approved types of backflow devices - air gap separation, double check valve assembly, reduced pressure backflow assembly, and spill resistant pressure vacuum breaker assembly. The device required is designated by the degree of hazard. Backflow devices are required to be tested annually. These devices are required to be repaired or replaced if the backflow device fails the annual test.
If you need assistance or information on testing or requirements please give the Public Works – Utilities Division a call. We will assist you in any way we can.
