From source to sink
Where Kingston water comes from
A plain-language tour of the lakes, rivers, or wells that feed Kingston, the plants that clean the water, and how it reaches kitchen taps. Lab grades for hardness, lead, and pH live on the water quality page.

Deep dive for households
Kingston drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Lake Ontario (at the mouth of the St. Lawrence River). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.
Kingston uses more than one treatment plant (Point Pleasant Water Treatment Plant; King Street Water Treatment Plant). Utilities often run plants in parallel so different neighbourhoods can be served, or so one plant can cover for another during maintenance. Point Pleasant Water Treatment Plant: Utilities Kingston / City of Kingston plant with a 1.2 m intake about 570 m offshore at roughly 18 m depth. Supplies Distribution Area 1 (Pressure Zones 1 and 2). King Street Water Treatment Plant: Second Lake Ontario plant with intake about 1 km offshore at roughly 18 m depth. Supplies Distribution Area 2 (and Area 3 via James Street booster).
After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Combined Kingston Drinking Water System serves about 132,500 people across three distribution areas with elevated tanks and reservoirs (O’Connor, Progress, Creekford, Tower Street, Third Avenue among them).
One detail that makes Kingston water feel local: Kingston’s twin plants sit at the Lake Ontario-St. Lawrence transition, drawing deep offshore water chosen after extensive intake siting studies. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
