This figure is over 3 years old; hardness may have changed.
The City of Portage la Prairie's 2020 annual report lists hardness of 172 mg/L as CaCO3 in treated water, from a single lab sample taken on 29 April 2020. The same table shows 285 mg/L in raw water, which is not used here. The 2024 and 2025 reports describe softening but print no hardness value, so this figure is six years old. Expect some scale on heating elements.
Health Canada: hardness above 200 mg/L is considered poor but tolerable; above 500 mg/L unacceptable.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
