Boil-water advisories are to protect public health. An advisory may be issued for preventive reasons, if there is a risk of contamination after repairs to waterworks conduits or due to non-compliant test results on the raw water (before treatment). The law obliges the municipality to issue an advisory even if the results are related to untreated water.
When water is boiled for at least one minute, all the micro-organisms that could affect human health are destroyed.
If even boiled water would not be safe to consume, a do-not-drink order will be issued and the city will take specific measures to ensure that the residents are informed.
If the advisory affects just a small part of the city, such as a few streets due to a watermain break, the city will distribute door hangers to all the affected residences. If a larger part of the city is affected, a variety of means will be used to inform the public:
- The automated call service can contact you by phone or text message. Make sure you are registered.
- An emergency message will be posted permanently on the city’s homepage.
- The information will be available on the city’s Facebook page.
- Journalists will also be informed.
Water boiled for one minute, or bottled water, must be used until further notice.
Schools, businesses, shops and institutions
Inform your clients that the water is unfit for consumption. Turn off water fountains and post signs in places where water is still available.
