Cross-Connection Control is the prevention of actual or potential connections between the public water supply and a source of contamination or pollution. Backflow prevention devices prevent the unwanted reversal of flow from an end user’s water system back into the public water supply.
Cross-Connection Control staff provide consultation for installation of backflow prevention devices in industrial, commercial and residential applications for domestic, fire protection and irrigation systems. Water connections are assessed for the degree of hazard they present and our personnel determine if a device is required on new or existing water lines serving structures. They also decide which containment type of backflow preventer must be installed.
Customers must then apply for an installation permit from the Inspections Division of the Planning and Development Services Department. The installation must be performed by an NC Licensed Plumber Contractor or Licensed Utility Contractor. Initial and annual testing of backflow prevention assemblies must be conducted by one of the approved and registered testing companies linked below. They will submit your test report to ensure compliance with state regulations. Continue reading for details on testing requirements.
Annual Backflow Assembly Testing Notifications
The State of North Carolina requires backflow prevention assemblies be installed on all cross-connections to help keep our water supply safe. These assemblies must be tested and certified every year to ensure that they are working properly.
Property owners are responsible for the installation, operation, testing and maintenance of required backflow prevention devices.
As of January 1, 2020, new state record-keeping guidelines went into effect that require public water systems to enforce the existing law, maintain a database of all cross-connections and report the annual test results within our water system.
Winston-Salem/Forsyth County Utilities has hired BSI Online to assist in administering the backflow test reporting program for our system. BSI Online sends out notification letters to customers listed in our records as having backflow prevention assemblies. The letters are sent 30 days prior to the assembly testing due date.
