Water Treatment and Distribution Systems Operations Program


Our Water Treatment and Distribution Systems Operations Program has been designed to prepare you for important work in water treatment operations. The Ontario Water Wastewater Certification Office (OWWCO) states that "water and wastewater operators serve their communities by protecting public health and the natural environment through the responsible treatment of drinking water and wastewater." Learn the skills you need to be able to shoulder this responsibility, and get the knowledge you need to write the various certification exams.
