Watershed to tap
How Edmonton 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.

Research confidence: high
E.L. Smith Water Treatment Plant
Upstream of much of the urban footprint; submerged mid-river intake with fish-return design. Larger of the two EPCOR plants serving Edmonton and capital-region wholesale customers.
Rossdale Water Treatment Plant
Near city centre; river intake experiences more urban stormwater influence. Longstanding plant site with continuous operation since early 1900s (current works mid-century).
EPCOR treats water and supplies Edmonton plus regional commissions (Parkland, Southwest, Northeast and others). On-site plant reservoirs buffer demand before high-lift pumps feed the transmission and municipal distribution networks.
All monitored parameters meet Health Canada guidelines.
All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
