Inspection of Small Drinking Water Systems

Since December of 2008, Public Health Units in Ontario have been responsible for inspecting small drinking water systems under Ontario Regulation 319/08.

Proprietors that make drinking water available to the public and do not use a municipal drinking water supply have small drinking water systems. These systems use private wells or surface water drawn from rivers, lakes or ponds and are common in rural areas. They include:

There are approximately 400 small drinking water systems in the geographic area covered by the Renfrew County and District Health Unit. Public Health Inspectors with the Health Unit are required to inspect and monitor each system on a regular basis.

Public Health Inspectors conduct a site-specific risk assessment on each small drinking water system. Based on the assessment, they determine what owners/operators must do to keep their drinking water safe for consumption. A directive for each system is issued which outlines operational requirements for water testing, water treatment and training. Owners/operators and water testing laboratories are required to notify the Health Unit when a water test indicates a problem with water quality.

For more information, or if you’re not sure whether your system is affected by the Small Drinking Water Systems regulations, contact the Renfrew County and District Health Unit at 613-735-8654 or 1 800 267-1097 extension 555 or visit the Ontario Ministry of Health and Long-Term Care's Small Drinking Water Systems site.
