Periodically, Cross Connection Control staff conducts a state-recognized school for tester certification and recertification. First, a 40 hour, five day backflow tester certification course is offered to individuals who are interested in testing backflows. A 16 hour, two day re-certification course is offered to certified testers in order to keep testers' skills and regulatory knowledge current. Individuals who are interested in becoming certified testers should review the course packet (PDF). The City of Durham also accepts the following approved backflow certification courses: Charlotte Water, Greenville, Fayetteville, Raleigh, and NC Rural Water.

The City of Durham also offers a Tester Orientation for students who attended a certification or recertification class at one of our approved reciprocity schools listed above and are interested in testing backflow preventers on the City of Durham’s Water distribution system.  Successful completion of the Durham Orientation class (already included in Courses taught by the City of Durham) is mandatory for every tester that wishes to perform backflow preventer testing in the City of Durham’s jurisdiction (including testers approved through reciprocity). The orientation class will cover local tester requirements and expectations. Copies of Durham’s Cross Connection Control Regulations will be provided during the class and time will be allotted for tester questions.
