From source to sink
Where Sainte-Marie water comes from
A plain-language tour of the lakes, rivers, or wells that feed Sainte-Marie, 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
Sainte-Marie drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Rivière Chaudière (permanent intake; two submerged screens ~2.4 m depth at 1065 rue Notre-Dame Sud). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.
Water is cleaned at Installation de production Sainte-Marie (X2134730) before it enters city pipes. City vulnerability report (2026): screening, coagulation/flocculation, sedimentation, ozonation, UV reactors, then chlorine gas disinfection and caustic soda pH adjustment. Feeds Saint-Joseph and Bisson reservoirs. MELCC lists chlorination, filtration, ozonation, and ultraviolet.
After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Serves ~13,500 people. Intake ~4 km south of the urban perimeter in an agricultural reach; booster station and dual reservoirs on the distribution side. City publishes annual quality bilans and Chaudière level monitoring.
One detail that makes Sainte-Marie water feel local: Sainte-Marie’s Chaudière intake sits in the flood-prone Moyenne-Chaudière corridor,the same river corridor that forced neighbouring towns onto alternate sources after Lac-Mégantic. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
