The Ministry of the Environment, Conservation and Parks and Walkerton Clean Water Centre are pleased to announce the upcoming launch of two new mandatory small drinking water system courses for individuals working towards their limited system operator certificate or Trained Person designation.
Replacing the previous Operation of Small Drinking Water Systems course, the following new courses will be specific to the type of drinking water system operated:
- Operation of Limited Systems course – for individuals working in limited ground water and limited surface water subsystems
- Operation of Small Systems for Trained Persons (O. Reg. 170/03) course – for individuals working in small drinking water systems serving designated facilities as defined under Ontario Regulation 170/03 on Drinking Water Systems.
The new courses will be launched in January 2026 and feature refreshed content focusing on the type of system. Both courses will be delivered in two steps:
- A self-paced e-learning component
- A scheduled live, virtual session with a trainer
The e-learning and virtual delivery of the courses provides better access and increased flexibility for participants.
Visit the Walkerton Clean Water Centre e-learning page in January to enroll in the Operation of Limited Systems course or the Operation of Small Systems for Trained Persons (O. Reg. 170/03) course.
If you have any questions, please contact Walkerton Clean Water Centre or the Ontario Water Wastewater Certification Office.
