Deep dive for households
Terrebonne drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Rivière des Mille Îles. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.
Water is cleaned at Régie d’aqueduc intermunicipale des Moulins (RAIM) production plant before it enters city pipes. Intermunicipal utility serving Terrebonne and Mascouche; surface supply from the Mille Îles River corridor. RAIM reports roughly 21 million m³/year across the two-city service area.
After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. RAIM produces and transmits; Terrebonne and Mascouche handle local distribution within their territories under the régie model.
One detail that makes Terrebonne water feel local: North-shore suburbs north of Montreal often sit on the Mille Îles rather than buying Island of Montreal / St. Lawrence aqueduct water,RAIM is that pattern for Terrebonne-Mascouche. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
