OpenStats picks for Cranbrook — everyday tap water
Cranbrook's 89 mg/L supply is relatively soft — filtration is mostly about chlorine taste. A certified pitcher or compact under-sink unit is enough for most homes.

Supply and treatment
How Cranbrook 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.

Treatment plants
Cranbrook Water Treatment Facility (Phillips Reservoir)
Joseph and Gold Creek waters divert into Phillips Reservoir (~2.3 billion litres) southeast of the city for settling, then chlorine and fluoride injection before distribution.
Distribution
Settled reservoir water is conveyed by large-diameter transmission main into the city distribution system.
All monitored parameters meet Health Canada guidelines.
All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
