Wastewater Treatment Plant Operators and Technicians

Certification or Licensing

Workers who control operations at wastewater treatment plants must be certified by the state in which they are employed. To obtain certification, operators must pass an examination given by the state. There is no nationwide standard, so different states administer different tests. Many states issue several classes of certification, depending on the size of the plant the worker is qualified to control. While some states may recognize certification from other states, operators who relocate may have to re-certify in the new state.
