Water Treatment

The City is fortunate to have access to two sources of drinking water: groundwater from a deep aquifer and surface water from Kempenfelt Bay. Before reaching the consumer this water is treated to protect public health.

Barrie's Surface Water Treatment Plant is closed to the public until further notice due to the COVID-19 pandemic. The facility remains open for deliveries.

Drinking Water Sources

The source of the water that comes out of your tap depends on where your live in the City. If you live in the northern portions of the City, your drinking water comes from groundwater that is extracted from the ground by municipal wells. If you live in the south end of the City, your drinking water is obtained from Kempenfelt Bay through an intake pipe nearly 1km from shore and 22m deep. You can access an interactive map here, and type your address into the search bar to determine which source you receive water from at your home or business!

Water Treatment Processes

Treatment of water depends on its source. Groundwater is naturally filtered through layers of rocky sediment and therefore requires less treatment than surface water. Click on the images below for a detailed description of the treatment processes at the City of Barrie.
