De Watergroep supplies this part of the Campine, a sandy region where lime is largely absent from the aquifers, so groundwater here tends to be softer than elsewhere in Belgium; some Flemish supply also comes from Albert Canal surface water. The reported 2024 figure is 75.3 mg/L CaCO₃ and no range is given for this supply area. This is moderately hard water: scale appears on taps and in kettles only over time, and most households manage with occasional descaling.
Belgian suppliers report hardness in °f (French degrees); 1 °f = 10 mg/L CaCO₃.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).

FAQ
Is Bree water hard or soft?
It is moderately hard: 75 mg/L as CaCO₃ (4.4 gpg, 4.2 °dH). The usual bands are soft < 60, moderately hard 60–120, hard 120–180 and very hard > 180 mg/L.
Is tap water in Bree safe to drink?
Hardness is not a health issue; it is about limescale, taste and appliances. Mains water must meet national drinking-water standards. Belgian suppliers report hardness in °f (French degrees); 1 °f = 10 mg/L CaCO₃.
How many grains per gallon is Bree water?
4.4 gpg, equal to 4.2 °dH, 7.5 °fH or 75 mg/L calcium carbonate.
What dishwasher salt setting should I use in Bree?
For 75 mg/L (4.2 °dH) check your manufacturer's table: level 2–3.
Do I need a water softener in Bree?
Not essential; a scale inhibitor protects the heater cheaply.
