Water & Wastewater Operator Certification Program

Water & Wastewater Operator Certification Program

The Montana Water and Wastewater Operator Certification program has two missions:

  • To protect the public health and the environment by having certified operators in direct responsible charge of the operation of water treatment plants, water distribution systems, or wastewater treatment plants.
  • To provide testing, recording, program information services and to ensure that comprehensive, ongoing training is given to Montana's water and wastewater operator community.
