Deep dive for households
Dolbeau-Mistassini drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Rivière Mistassini (sector intakes for Dolbeau and Mistassini). That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.
Dolbeau-Mistassini uses more than one treatment plant (Usine Hamel (secteur Dolbeau); Usine Sainte-Marie (secteur Mistassini)). Utilities often run plants in parallel so different neighbourhoods can be served, or so one plant can cover for another during maintenance. Usine Hamel (secteur Dolbeau): Filtration + chlorination plant from early 1970s; city seeking rebuild funding (~$19M) as facility ages out of standards. Usine Sainte-Marie (secteur Mistassini): Filtration + chlorination for Mistassini sector per MELCC registry / city annual bilans.
After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Two main production plants serve former Dolbeau and Mistassini sectors across the Mistassini River.
One detail that makes Dolbeau-Mistassini water feel local: A merged city still runs twin filtration plants on opposite sides of the Mistassini,Hamel's rebuild is the current flashpoint. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
