Supply and treatment

How Moncton 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

  • Turtle Creek Reservoir
  • Tower Road Reservoir (Turtle Creek watershed)

Treatment plants

  • Moncton Drinking Water Treatment Plant

    City-owned Level 4 plant in the Turtle Creek watershed; operated under long-term contract by Veolia; coagulates/filters and chemically conditions water for corrosion control; cyanobacteria (ozone / PAC) upgrades underway.

Distribution

Tri-community utility: City of Moncton supplies treated Turtle Creek watershed water to Moncton, Dieppe, and Riverview. Reservoirs sit about 10 km southwest of Moncton in Albert County; treated water is stored and pumped into the shared distribution system.

Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target.

One or more parameters exceed a Health Canada drinking water guideline or turbidity target.
