Water hardness in Poulseur (Liège): 34°fH, quality index 5/10. Official Belgian data.
✓ Compliant with sanitary standardsPoulseur has hard water (34°fH). Weekly descaling is recommended. A water softener becomes worthwhile above 35°fH.
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. Poulseur's water is hard at 34°fH.
Maintenance budget: ~£95/year
For 2 persons, water at 34°f deposits around 1.6 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~54 mg per litre
Your water provides 54 mg of calcium/L, which is 5% of the recommended daily intake.
Filter jug: cartridge every 4 months
At 34°f, replace the cartridge every 4 months. An under-sink filter lasts 6 to 12 months.
The tap water hardness in Poulseur is 34°fH, corresponding to hard water. In comparison, the Belgian national average is 30°fH and the Liège provincial average is 30°fH.
Yes. The water in Poulseur is sanitary compliant (European Directive 2020/2184). The hardness of 34°fH affects taste and appliance maintenance, not safety. Belgian tap water is subject to strict regular monitoring by SWDE (Wallonia).
With 34°fH, a water softener is a worthwhile investment in Poulseur. Limescale reduces the lifespan of boilers, washing machines and coffee makers and increases energy consumption by 10 to 15% per mm of scale. An anti-scale filter is a minimum at this hardness level.
A hardness of 34°fH corresponds to approximately 54 mg of calcium per litre, or 5% of the recommended daily intake. This calcium is not dangerous; hard water can even contribute to your daily calcium intake.
