Flanders has decided to require new buildings and deep renovations to include larger rainwater tanks. A measure justified by climate change, and by the fact that we are now faced with both long periods of drought and heavy rainfall. Note also that the presence of such cisterns is beneficial in flood control.
“They thus have a “buffering” effect. This water is used gradually and this reduces the quantity of water which arrives at once in the rivers or the sewers during critical periods. »
➜In the North of the country, as in Brussels, rainwater tanks are already compulsory in new houses, which is not the case in Wallonia.
➜One municipality in five conditions the issue of a planning permit to the presence of a rainwater tank: and bonuses are possible
