Range across supply zones: 165–207 mg/L.
De Watergroep and Farys supply this part of Flanders with a mix of groundwater and canal-fed surface water, so hardness sits between the soft sandy Campine and the hard chalk areas. The 2024 figure is 186.2 mg/L CaCO₃, within a reported range of 165.4 to 207.0 mg/L, which reflects the different supply areas that serve the town. This is very hard water: expect heavy limescale on taps, glass and heating elements, and higher detergent and descaling needs.
Belgian suppliers report hardness in °f (French degrees); 1 °f = 10 mg/L CaCO₃.

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).
