Drinking water

Flood-related drinking water updates

Drinking water supplied by the City of Ottawa remains safe for residents. The water levels have not impacted the high quality of water the City provides to residents.

The City has two water purification plants, one on Lemieux Island and one in Britannia. Both are functioning as they should be.

Staff continue to monitor the water facilities and are prepared to address any changes should they arise.

Private well water 

Residents who have private wells affected by flooding are advised:

  • Stop using your well water and use another potable water source such as bottled water for all water use.
  • If you do not suspect chemical contamination, bring it to a rolling boil for at least one minute and let it cool before any use. Refrigerate your boiled water until it is used.

For more information on well water quality during a flood, please visit Ottawa Public Health’s website.

The City has opened a drive-through commodity distribution point to provide drinking water and hand sanitizer to residents whose private wells are affected by flooding. Affected residents may pick up water at Fire Station 63 at 341 Bayview Drive, between noon and 7 pm.

Water purification, quality and distribution

Every day, the City of Ottawa’s central water supply provides safe drinking water to approximately 865,000 residential, commercial, and industrial customers. Using the Ottawa River as its source, drinking water is treated at two purification plants and subsequently distributed through more than 3,000 kilometres of water mains before arriving at your tap. In rural areas, the City operates six groundwater well systems.

More than 100,000 water quality tests are performed on drinking water samples annually, covering 350 parameters. The results demonstrate that City of Ottawa customers receive high quality drinking water that meets all federal guidelines and provincial standards.

The City prepares an annual report for each municipal drinking water system, in compliance with the Safe Drinking Water Act.
