Water Treatment

The City must be capable of providing an adequate supply of safe drinking water for the growth envisioned by its approved Official Plan. Approximately half of Barrie is supplied with surface water; the other, groundwater.

Surface Water Treatment 

Open pdf: Surface Water Process

Approximately half of the City is supplied with surface water, primarily the southern portions of the City. See Surface Water Supply map.

The Process: Surface water is drawn from Lake Simcoe (Kempenfelt Bay) through a pipe nearly one kilometer from shore and 26 meters deep. Water is pumped to a low-lift pumping station close to the shoreline, then up to the Surface Water Treatment Plant (SWTP) located at 20 Royal Parkside Drive. The SWTP began supplying water to Barrie in August of 2011.

Tours Available: The SWTP offers pre-arranged tours to the public. A tour of the facility can be booked by contacting Jamey Adams, Supervisor of Surface Water Supply, at 705-739-4220 x6180 or

Groundwater Treatment

Open pdf: Groundwater Process

Approximately half of Barrie is supplied with groundwater, mainly including the north portions and the city centre (areas not highlighted in the Surface Water Supply map).

The City currently has 12 wells, 3 in-ground reservoirs, 3 water towers and 6 booster pumping stations that supply 5 major pressure zones throughout Barrie. Water is supplied from wells drilled into a deep aquifer that is not under the direct influence of surface water.

Wastewater Treatment

Wastewater is the mixture of liquid and solid materials that residents and businesses flush down toilets and empty down sinks and drains. This material is directed to the plant through a network of pipes that make up the City’s sanitary sewer system to the Wastewater Treatment Facility. Treating wastewater is a process of cleaning it to remove solids, chemicals and other undesirable material before it is pumped to Lake Simcoe.
