There is no evidence of contamination of the water system, and the city is issuing this boil water advisory as a precautionary measure until further notice. This includes water used for brushing teeth, making ice, washing raw foods, and preparing drinks, as well as water for pets. Water used for bathing, laundry and lawn irrigation does not need to be boiled. The boil water alert is anticipated to be lifted within 48 hours.
The water should be boiled for at least one minute and allowed to cool in a covered container. Bottled water can be used as an alternative.
What should I do?
Consult the map on the city’s website and if you are within the identified boundary of the boil water advisory then you should not drink city tap water without boiling it first. Bring water to a boil and let it boil for one minute, and then let it cool before using. Alternatively, bottled water can be used for drinking, brushing teeth, making ice, and food preparation until further notice. Boiling kills bacteria and other organisms that could be in the water.
What happened? What is being done?
These precautionary actions are being taken due to a temporary loss of water pressure in the water distribution system within the map boundary. Whenever a water system loses pressure for any significant length of time, precautionary measures are recommended. The loss of water pressure was due to multiple water main breaks near the area of Plymouth Road between Green and Huron Parkway. City staff are working to get the break repaired. The break has been isolated and pressure has been restored in the affected area. However, because there was a temporary loss in pressure, the precautionary advisory has been put in place.
When will the advisory be lifted?
City staff has collected water samples from the affected area and will be analyzing those samples over the next 24 to 48 hours. Once it is determined that the water quality meets the state drinking water standards, the advisory will be lifted.
Has contamination of the water system been detected?
No contamination has been detected at this time. The boil water advisory is precautionary until water quality analyses are completed to confirm the water is safe to drink.
What if I live in the affected area and have already drank the water?
No water contamination has been detected at this time, the boil water advisory is precautionary. Until the advisory is lifted customers in the affected area should continue to boil their water for drinking, brushing teeth, making ice, and food preparation. Since no contamination has been detected, there is no action you need to take if you have consumed the water unless you are not feeling well. If you are feeling unwell you should contact your medical provider.
What if my residence or business is just outside the affected area?
If your residence or business is outside of the affected area, you do not need to take action or boil water. It is safe for all uses.
