Source: City of Regina, 2025 Drinking Water Quality Report (2025) · data checked 2026-10-20
The City of Regina's 2025 report lists hardness of 203 mg/L from routine testing at 18 distribution sampling locations. The report does not say whether this is an average or a single result. Regina is supplied mainly from the Buffalo Pound Water Treatment Plant. A small supplemental groundwater supply tests much harder and is not part of this figure. Expect visible scale in kettles and on fixtures.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
