South Jordan City is dedicated to providing our residents and customers with safe, clean, drinking water. Maintaining a backflow prevention program is one of the ways the City accomplishes this goal.
A joint responsibility between the City and its residents/customers must exist to ensure all areas of the water distribution system are adequately protected. The City will provide a safe, adequate water supply to the residents/customers who in turn will maintain their plumbing system in compliance with local ordinances, requirements, codes and policies.
A backflow incident can seriously affect the quality and safety of our drinking water supply. Backflow is the reverse flow of contaminated water or other substances from a user's water system back into the public drinking water system. Backflow can occur if your plumbing system is physically connected (a cross connection) to any source of contamination or pollution. Common examples of possible cross connections include landscape sprinkling systems, hose attachments for utility sinks, and garden hoses. Backflow prevention assemblies provide the public water system with protection against contamination or pollution.
The City's Backflow Technician will perform a hazard assessment of all commercial buildings and residential irrigation systems every three years. Assemblies and devices that require annual testing are the responsibility of the property owner, the City will send a reminder notice as the due date approaches. Every new business will be inspected prior to the issuing of the certificate of occupancy.

The only approved backflow assembly for irrigation/sprinkler systems is the Reduced Pressure Zone Assembly (RP, RPZ). RPs require annual testing by a state certified backflow technician. Locate a state certified technician in your area from this list. In addition to the RPs vacuum breakers are required for all hose outlets. These can be purchased at most sprinkler supply or hardware stores.
