Deep dive for households

Cranbrook drinking water starts as surface water (rivers, lakes, or reservoirs). The named sources on the utility record are Joseph Creek, Gold Creek, Phillips Reservoir. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Cranbrook Water Treatment Facility (Phillips Reservoir) before it enters city pipes. 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.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Settled reservoir water is conveyed by large-diameter transmission main into the city distribution system.

One detail that makes Cranbrook water feel local: Phillips Reservoir is Cranbrook’s sole raw-water storage,watershed forest health and creek turbidity drive supply risk more than a large lake intake would. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
