Water hardness in Filot (Liège): 17°fH, quality index 8/10. Official Belgian data.
✓ Compliant with sanitary standardsFilot has soft water (17°fH). Low limescale risk: descale appliances every 3 to 4 months as a precaution.
Belgian tap water is subject to European Directive 2020/2184. The sanitary compliance indicator shows whether the latest official analyses found any non-conformities on parameters such as bacteriology, nitrates, pesticides or heavy metals.
The TH (Total Hardness) measures calcium and magnesium content. Below 15°fH: very soft. From 15 to 25: soft. From 25 to 32: moderately hard. From 32 to 42: hard. Above 42: very hard. Filot's water is soft at 17°fH.
Maintenance budget: ~£48/year
For 2 persons, water at 17°f deposits around 0.8 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~27 mg per litre
Your water provides 27 mg of calcium/L, which is 3% of the recommended daily intake.
Filter jug: cartridge every 7 months
At 17°f, replace the cartridge every 7 months. An under-sink filter lasts 6 to 12 months.
The tap water hardness in Filot is 17°fH, corresponding to soft water. In comparison, the Belgian national average is 30°fH and the Liège provincial average is 30°fH.
Yes. The water in Filot is sanitary compliant (European Directive 2020/2184). The hardness of 17°fH affects taste and appliance maintenance, not safety. Belgian tap water is subject to strict regular monitoring by SWDE (Wallonia).
At 17°fH, a water softener is optional in Filot. Regular descaling (every 1 to 3 months depending on appliance) and a pitcher filter are sufficient to limit limescale buildup.
A hardness of 17°fH corresponds to approximately 27 mg of calcium per litre, or 3% of the recommended daily intake. This calcium is not dangerous; hard water can even contribute to your daily calcium intake.
