Backflow Tester List

State rules

North Dakota

The North Dakota Department of Environmental Quality says the Administrative Code requires water suppliers to provide cross-connection control within their own water supply systems. Commercial and residential facilities protect the potable supply under the local plumbing code, or under the North Dakota Plumbing Code if there is no local code. A containment program is required. It covers potential cross-connections in publicly owned buildings and property, such as a city hall or fire station, plus known cross-connections the system learns about. A comprehensive program that surveys private customers such as car washes, restaurants, and apartments is voluntary. The page announces backflow certification and recertification courses but does not say DEQ issues the tester card.

The containment program requires the public water system to survey publicly owned buildings and property and to protect identified hazards with the proper backflow prevention device or assembly. Known cross-connections fall under that required program when protection of public health requires it. The comprehensive program would extend surveys to customer premises and is described as voluntary. The page says Appendix F is no longer applicable and has been removed. Program templates and annual reports go to DEQ-MF-Inspection@nd.gov. The contact printed for the program is Jacob Schafer at the Municipal Facilities Division, 701-328-6375.

The page lists a backflow certification course and a recertification course and says the training qualifies as continuing education for water and wastewater operators. It points readers to an outside training site for more information. That is a training announcement. It is not a sentence that creates a North Dakota tester license or that names ASSE, ABPA, or AWWA as the accepted personal credential. A tester’s authority for a particular assembly still depends on the plumbing code that applies and on what the water system requires inside its containment program.

A customer in a privately owned building should ask whether the water system has chosen the voluntary comprehensive program. If it has not, the required program covers the system’s own facilities and known cross-connections, while the plumbing code still applies to the building. The page’s training notices are continuing-education announcements for operators. They are not a state tester roster, and the page states no test fee.
