Winnipeg's drinking water quality
Public Water System Operating Licence and annual audit report
Manitoba Health and Manitoba Water Stewardship regulate the quality of our drinking water using the Manitoba Drinking Water Safety Act 
and the Guidelines for Canadian Drinking Water Quality .
The Province's Office of Drinking Water issues an operating licence for our water system. They also perform an annual compliance audit which provides details of the licensing requirements and the water system performance in regard to the terms and conditions set out in the operating licence.

We test our water each step of the way, from Shoal Lake to the tap, to ensure safe, high-quality drinking water. Because water quality is so important, we do more testing than the provincial government requires.
Occasionally, test results for some locations don't meet a drinking water quality standard. In these cases, we take corrective action immediately (e.g., retesting the water) to ensure our water remains safe.
We will inform Winnipeg residents immediately if there is ever a water quality problem that could affect public health.
