Range across supply zones: 171–180 mg/L.
De Watergroep supplies 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 175.6 mg/L CaCO₃, within a reported range of 171.3 to 179.8 mg/L, so the exact value depends on your street. This is hard water: expect visible limescale on taps and glass, and a shorter life for heating elements unless they are descaled.
Belgian suppliers report hardness in °f (French degrees); 1 °f = 10 mg/L CaCO₃.

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).
