Supply and treatment
How Levis draws, treats, and distributes drinking water, from municipal and utility publications. Chemistry grades above come from separate parameter records; this section does not invent plant lab figures.
Source type
Surface water
Research confidence: high
Source waters
- Saint Lawrence River
- Chaudière River
Treatment plants
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).
Distribution
Three production plants feed sectorized distribution networks; the city has been interconnecting plants so one can backstop another during source emergencies.
All monitored parameters meet Health Canada guidelines.
All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
