How much could rainwater save you?
Let’s start with the address of the house: it tells us your water supplier and its exact tariff.
Your data stays with Weber Water.
Indicative estimate based on the 2026 tariffs published by the suppliers (Walloon CVA 2.748 €/m³, Social fund 0.0339 €/m³, Vivaqua BRUGEL tariffs, Flemish VMM tariffs with maximum municipal contribution), average rainfall in Uccle (≈ 850 mm/year) and a tank filling simulated per ten-day period. Some municipal utilities do not publish their 2026 tariff: the last known tariff is used.
