Local Water Analysis
Solving Oshawa's Specific Water Challenges
Homes across Oshawa receive municipal water sourced from Lake Ontario (Oshawa WTP).
Mix of post-war residential homes, university district housing, and rapidly expanding North Oshawa subdivisions. Over time, unfiltered hard minerals accumulate inside tankless water heaters, leave stubborn cloudy spots on glass shower doors, and degrade fixtures throughout the home.
What Oshawa Homeowners Deal With
- Scale buildup shortening water heater and appliance operating life
- Dry skin and dull hair caused by municipal chlorine
- Pure reverse osmosis drinking water for growing families

Where Your Water Comes From
Oshawa's Water Source & Treatment
Understanding where Oshawa's water comes from and how it's treated helps you make informed decisions about your home's water quality.
Oshawa receives its municipal water from Lake Ontario, treated at the Oshawa Water Treatment Plant operated by the Region of Durham. The facility uses conventional coagulation, flocculation, sedimentation, and rapid sand filtration, followed by chlorine disinfection. Treated water is pumped through Oshawa's distribution network, serving communities from the Lakeview waterfront to the expanding North Oshawa subdivisions near Windfields and Kedron. Oshawa's mix of post-war homes near the lakefront and newer construction in the north means water age and pipe conditions vary significantly across the city.
