For more than 70 years, the R.C. Harris Water Treatment Plant has provided safe drinking water to Toronto’s residents and York Region.
Located in an attractive east-end community called The Beach, the plant is well known for its architectural features. It is often described as a “sparkling jewel by the lake”.
Where does the water come from?
One of four City water treatment plants, the R.C. Harris takes raw water from Lake Ontario, then cleans, disinfects and converts it into safe potable/drinking water for pumping into the City’s distribution system.
