Deep dive for households

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

Water is cleaned at Usine de filtration de Rimouski before it enters city pipes. City surface plant on the Rimouski River supplying the urban aqueduct.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. City distribution with river intake and in-town storage.

One detail that makes Rimouski water feel local: Rimouski’s namesake river is both the municipal source and a defining geographic corridor through the city. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
