Water hardness in Seraing (Liège): 12°fH, quality index 9/10. Official Belgian data.
✓ Compliant with sanitary standardsSeraing has very soft water (12°fH). No limescale issues at all: your appliances will last longer without special care.
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. Seraing's water is very soft at 12°fH.
Maintenance budget: ~£34/year
For 2 persons, water at 12°f deposits around 0.6 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~19 mg per litre
Your water provides 19 mg of calcium/L, which is 2% of the recommended daily intake.
Filtration not required
Your soft water does not require filtration. A jug filter remains useful for taste.
The tap water hardness in Seraing is 12°fH, corresponding to very soft water. In comparison, the Belgian national average is 30°fH and the Liège provincial average is 30°fH.
Yes. The water in Seraing is sanitary compliant (European Directive 2020/2184). The hardness of 12°fH affects taste and appliance maintenance, not safety. Belgian tap water is subject to strict regular monitoring by SWDE (Wallonia).
At 12°fH, a water softener is optional in Seraing. Regular descaling (every 1 to 3 months depending on appliance) and a pitcher filter are sufficient to limit limescale buildup.
A hardness of 12°fH corresponds to approximately 19 mg of calcium per litre, or 2% of the recommended daily intake. This calcium is not dangerous; hard water can even contribute to your daily calcium intake.
