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.
How it reaches your street
Settled reservoir water is conveyed by large-diameter transmission main into the city distribution system.

Reading this page
Cranbrook's most recent drinking water sample (2026-07-22) reports hardness of 89 mg/L, classified as moderately hard, and pH 7.2, drawn from a groundwater water source and treated at Cranbrook Water Treatment Plant. Lead measured 0.1 μg/L and fluoride 0.6 mg/L.
Free chlorine measured 0.6 mg/L in this sample. No E. coli was detected in this sample.
Cranbrook's hardness of 89 mg/L is below the British Columbia average of 139 mg/L across 31 tracked municipalities, with a provincial average pH of 7.5.
These readings summarize a single compliance snapshot, not a certification of the water reaching your tap. Test your own water periodically, especially on a private well, and consider a softener if hardness is classified hard or very hard.
How to use this page: read the headline metrics first, then where the water comes from (map and tap story), then the parameter table and source footer.
All monitored parameters meet Health Canada guidelines.
All health parameters meet Health Canada guidelines with comfortable pH, hardness, and turbidity.
