Understanding Oakville's water
Source: Halton Region, 2025 distribution system averages.
Where does Oakville's water come from?
Oakville's water comes from Lake Ontario and is treated by Halton Region, mainly at the Burloak and Oakville water purification plants. It meets safety standards, but residents often report:
- Chlorine taste and odour
- Hard water, averaging 124 mg/L
- Limescale in appliances and on fixtures
- Soap scum and dry skin after bathing
Besides using less soap and detergent, softened water keeps scale out of your water heater, which helps it heat efficiently for longer.
