Proportion of impermeable surfaces

The waterproofing (operation to prevent water penetration) of soils in urban areas has increased the proportion of precipitation that trickles into the drainage network. During heavy downpours, this precipitation is concentrated in the valleys of the Brussels territory, which can lead to flooding, due to the saturation of the drainage network and the storm basins. The indicator measures the proportion of impermeable surfaces in the districts of Brussels.
