- Deep aquifer groundwater wells
Treatment plants
Barrie Surface Water Treatment Plant
Plant at 20 Royal Parkside Drive treating Kempenfelt Bay / Lake Simcoe water. Intake about 750 m offshore at roughly 26 m depth. Screening, flocculation, membrane filtration, GAC for taste and odour, and chlorination. Rated capacity 60,000 m³/day.
Municipal groundwater wells (multiple sites)
Twelve groundwater wells across the city (Anne Street, John Street, Sarjeant, Johnson, Heritage Park, Centennial Park, Brown Wood, Cross Street and others). Groundwater generally receives sodium silicate for iron and chlorination.
How it reaches your street
Mixed surface/groundwater system with three in-ground storage facilities, seven booster stations, three elevated towers, and roughly 690-700 km of watermains. Neighbourhood source depends on water-supply zone.

Reading this page
Barrie's most recent drinking water sample (2026-07-22) reports hardness of 129 mg/L, classified as hard, and pH 7.2, drawn from a groundwater water source and treated at Barrie Water Treatment Plant. Lead measured 0.1 μg/L and fluoride 0.6 mg/L.
Free chlorine measured 0.6 mg/L in this sample. No E. coli was detected in this sample.
Barrie's hardness of 129 mg/L is below the Ontario average of 182 mg/L across 51 tracked municipalities, with a provincial average pH of 7.5.
These readings summarize a single compliance snapshot, not a certification of the water reaching your tap. Test your own water periodically, especially on a private well, and consider a softener if hardness is classified hard or very hard.
How to use this page: read the headline metrics first, then where the water comes from (map and tap story), then the parameter table and source footer.
All monitored parameters meet Health Canada guidelines.
All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
