Water Advisory Listings and Non-potable Systems

Water Advisories are issued for a drinking water system or a drinking water source by a Medical Officer of Health (Manitoba Health) due to a confirmed or suspected water quality problem. Affected residents and businesses are notified in the event an advisory is issued and provided with instructions on precautionary measures.

Boil Water Advisory Fact Sheets provide information on recommended actions when a water advisory is issued.

Drinking water supply systems in Manitoba are classified into three categories for regulatory and monitoring purposes. A copy of the current listing of Manitoba communities under Water Advisory is available by the following reports:

Boil water advisories (BWA) are issued in instances where drinking water may be compromised by bacteria or micro-organisms and water users are advised not to consume the water unless it is boiled for one minute, or otherwise disinfected.

Drinking water avoidance advisories (DWAA) are issued in instances where drinking water is compromised by contaminants that cannot be killed or removed by boiling the water. Water users are asked to use an alternate safe source of water such as bottled water.

Water quality advisories (WQA) are issued in instances where drinking water may pose a low risk to health and water users can take actions to reduce their risk other than boiling the water.

Non-potable systems provide water to permanent dwellings for non-potable purposes. An alternative source of water, such as bottled water, must be used for drinking, brushing teeth, preparing food or beverages, including ice and infant formula.
