Deep dive for households

Saint-Georges drinking water starts as surface water (rivers, lakes, or reservoirs). The named sources on the utility record are Rivière Chaudière, Lac Poulin (emergency / alternate). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Usine de filtration Ville de Saint-Georges before it enters city pipes. Major filtration plant (~$33M) with ozonation, carbon, corrosion control, chlorination (MELCC). Serves ~90% of population from Chaudière intake.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. ~220 km watermains; multiple reservoirs. Lac Poulin used as Plan B during Lac-Mégantic hydrocarbon spill on the Chaudière.

One detail that makes Saint-Georges water feel local: After Lac-Mégantic, Saint-Georges shut the Chaudière intake and switched to Lac Poulin,proving why Chaudière towns keep alternate sources. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
