Water quality reporting

Manitoba Conservation and Water Stewardship, Winnipeg Regional Health Authority and Manitoba Health, Healthy Living and Seniors regulate the quality of our drinking water using the Manitoba Drinking Water Safety Act and the Guidelines for Canadian Drinking Water Quality .

Our Operating Licence requires that we regularly monitor the quality of our drinking water. This includes daily routine tests for chlorine and turbidity. The routine tests are reported on a monthly basis to Manitoba Conservation and Water Stewardship. We also test for lead, total trihalomethanes and fluoride on a monthly basis. Bacteria tests are done on a weekly basis and are reported directly to the regulator by the contract laboratory that does the analysis.

Annual water report

The Act and our Operating Licence require that we submit an annual report of our water supply system to the Office of Drinking Water and post a copy of the report. The annual report includes the information provided above for the year specified.

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.

If you would like more information on Winnipeg's water, check out the other information on our web site or contact us.
