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.

Drinking Water Sources

The source of the water that comes out of your tap depends on where your live in Barrie.

Groundwater: If you live in the northern portions of Barrie, your drinking water comes from groundwater that is extracted from the ground by municipal wells.

Surface Water: If you live in the south end, your drinking water is obtained from Kempenfelt Bay through an intake pipe nearly 1km from shore and 22m deep.

Access the interactive Water Supply Zones map and search your address to determine the source of water you receive 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 to download detailed descriptions of the treatment processes.

Frequently Asked Questions

Does the drinking water source impact water hardness?

Yes, the source water impacts hardness levels. 

Essentially, areas serviced by the ground water system can expect to see a higher mineral content (hardness) with the range typically being 13-15 grains per gallon, while in the areas serviced by surface water an average hardness of 8-10 grains per gallon can be expected. (The “grains per gallon” value is generally used by softener manufacturers and installers and is referenced within the instruction manuals for softeners.) 

The reason for the increased hardness is due to the fact that ground water (in deep aquifers) has accumulated there over extremely long periods of time after filtering through layer upon layer of sand, soil, clay and rock, picking various minerals like iron, calcium, manganese, etc. 

For both drinking water sources, the water provided is of the highest quality and meets or exceeds the regulatory requirements imposed by the Ministry of the Environment, Conservation and Parks.

Is Fluoride added into Barrie's drinking water?

No, Fluoride is not added to the water, however, small amounts can be naturally occurring.
