Small drinking water systems that are regulated under Ontario SDWS Regulation 319 are assessed by Public Health Inspectors (PHIs). The PHI will issue a directive outlining what the owner/operator of the system must do to keep the drinking water safe. The directive may include, but is not limited to, water testing requirements, treatment requirements and operator training.
WCWC offers a wide variety of courses related to treatment, distribution and compliance to assist small systems.
Contact Ontario Water Wastewater Certification Office (OWWCO) for inquiries regarding operator licensing and renewals.
