Who regulates backflow tester certification in Idaho

Certification is regulated at the state level: one credential is valid across Idaho.

The authority for backflow tester credentials in Idaho is Idaho Division of Occupational and Professional Licenses (DOPL), Board of Drinking Water and Wastewater Professionals. DOPL/WWP Board was and remains the licensing authority; Idaho DEQ is not the certifying agency. Effective October 14, 2025, the renewal cycle moved from annual to biennial (phased in by license-holder birth-year parity), not an agency handoff. Pre-transition fee was $35/year; DOPL communications say fees "double" under the biennial cycle, but no official page states the current biennial dollar figure, so fee is left null rather than inferred.
