South Bend Water Works: backflow testing rules

Who must test

• Any business with a possible hazard to the public water supply, and any residence with an irrigation system, must install, maintain and regularly test a backflow prevention device. Source.
• The utility requires containment with a device on the downstream side of the meter and requires a reduced pressure principle device for facilities with a cross connection hazard. Source.
• Devices in place for hazards must be tested after installation, after any repair, and at intervals no greater than one year; the utility may require more frequent testing. Source.

How the report is filed

• Test reports go to the utility and the customer after each test, by email to Backflow@southbendin.gov or by mail to the Backflow Prevention Program. Source.
• Both the utility and the customer must keep testing documentation for at least three years. Source.

Tester registration

• The utility links customers to the IDEM list of Indiana certified testers rather than a utility list. Source.
