When the people of Ontario reach for a glass of tap water, they expect their water to be safe. Across the province, it takes knowledgeable, conscientious people to operate our regulated systems and help ensure that they deliver clean, potable water, and that wastewater is discharged in an environmentally safe manner.

Certifying Ontario’s operators through the Drinking Water and Wastewater Operator Certification Program helps to ensure:

  • the protection of human health;
  • the protection of the aquatic environment; and,
  • the efficient operation of water/wastewater infrastructure.

Certified operators are permitted to operate in Ontario by meeting the requirements of Ontario Regulations 128/04 and 129/04. They are expected to follow all applicable laws, and to act honestly, competently, and with integrity for the public’s protection.
