Terrebonne drinking water path

• Source & supply

  Rivière des Mille Îles

  RAIM produces and transmits; Terrebonne and Mascouche handle local distribution within their territories under the régie model.

  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.
