Water Works Operator Certification Program

The Water Works Operator Certification Program requires all community and non-community/non-transient public water systems in New Hampshire to be under the responsible charge of a primary certified drinking water system operator. The primary operator is responsible for all operational aspects and for overseeing system maintenance. Other water system personnel making decisions directly affecting water quality or quantity must also be certified. A public water system represents a significant lifelong investment for any community, demanding that operators be fully trained and certified. This program provides assurance that water works operators have basic knowledge and understanding to provide a safe, adequate, and reliable supply of water to their customers.

Although there is no requirement for operators to attend training to become certified it is strongly recommended. The available introductory courses enhance the ability of an applicant to pass the certification exam. Operators applying for recertification are required to complete training contact hours (TCH) pertaining to the operation, design, or maintenance of public water systems. These courses must be approved by the DWGB prior to the training. A partial list of approved scheduled courses presented by NHDES and our partners is presented under Training.
