Deep dive for households

Salaberry-de-Valleyfield drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Baie Saint-François (St. Lawrence / Lac Saint-François system). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Usine de filtration Salaberry-de-Valleyfield (Avenue du Centenaire) before it enters city pipes. Complete treatment: screening, ozone pre-disinfection, GAC filtration (9 filters), chlorination. Capacity cited ~68,000 m³/day.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Two raw intakes in Baie Saint-François. Production has fallen even as population grew (conservation / leakage work).

One detail that makes Salaberry-de-Valleyfield water feel local: Valleyfield is nicknamed Quebec's Venice yet drinks from Baie Saint-François,not the Beauharnois Canal that defines its industrial shoreline. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
