The water supply system in Kitchener-Waterloo is a complex and multi-faceted process designed to ensure safe drinking water for the community. The primary sources of water include both surface water from lakes and rivers and groundwater.
The water is disinfected using a multi-barrier including filtration, ozonation, chlorination, and ultraviolet light. The finished water enters a large underground storage reservation where it is mixed with treated groundwater before entering the distribution system.
Where is it treated?
About 20 to 25% of Waterloo
Region's drinking water is from the Grand River. Water from the Grand River goes through a multi-step treatment process at the Manheim Water Treatment Plant.
Our drinking water comes from two primary natural resources: surface water(think lakes and rivers), and groundwater. Typically, the water flows from intake points to a water treatment facility and then through our public water systems into our homes.
