Fordon is a district of Bydgoszcz, served by MWiK Bydgoszcz. The utility's district table gives a range of 370 to 437 mg/L CaCO₃, and our 403.5 mg/L is the midpoint, so it is computed. The table dates from 2021 and may be out of date. This is very hard water, and scale in kettles and boilers is the main practical issue.
Polish suppliers report total hardness in mg/L CaCO₃; the drinking-water regulation range is 60–500 mg/L.

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).
