Drinking Water Quality and Supply

From source to sink

Where Levis water comes from

A plain-language tour of the lakes, rivers, or wells that feed Levis, 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

Levis drinking water starts as surface water (rivers, lakes, or reservoirs). The named sources on the utility record are Saint Lawrence River, Chaudière River. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Levis uses more than one treatment plant (Usine de production Lévis (secteur Desjardins); Usine de production Saint-Romuald; Usine de production Charny). Utilities often run plants in parallel so different neighbourhoods can be served, or so one plant can cover for another during maintenance. Usine de production Lévis (secteur Desjardins): Draws from the Saint Lawrence River; multi-barrier treatment including filtration, ozonation, UV, and chlorination. Usine de production Saint-Romuald: Saint Lawrence intake serving the Saint-Romuald distribution sector.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Three production plants feed sectorized distribution networks; the city has been interconnecting plants so one can backstop another during source emergencies.

One detail that makes Levis water feel local: After the Lac-Mégantic disaster contaminated the Chaudière upstream, Charny temporarily switched to the Beaurivage River,an episode that drove interconnection investment between Lévis plants. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.

Surface water

Rivers, lakes, or reservoirs, not underground wells as the main draw.

Named source waters

  • Saint Lawrence River
  • Chaudière River

Treatment plants

These are the buildings that filter and disinfect water before it enters city pipes.

  • Usine de production Lévis (secteur Desjardins)

    Draws from the Saint Lawrence River; multi-barrier treatment including filtration, ozonation, UV, and chlorination.

  • Usine de production Saint-Romuald

    Saint Lawrence intake serving the Saint-Romuald distribution sector.

  • Usine de production Charny

    Draws from the Chaudière River for western Lévis communities (Charny, Saint-Nicolas, Saint-Rédempteur, Breakeyville, Saint-Étienne-de-Lauzon).

How it reaches your street
