Bonus for making permeable surfaces

The City of Brussels gives its inhabitants (postal codes: 1000, 1020, 1120, 1130 Brussels) a bonus for making permeable surfaces (replacement of impermeable ground cover in courtyards and gardens).

The Brussels Region is a very densely built area. Rainwater flows on largely impermeable soils and ends up in the sewerage network. In the case of heavy rain showers, some collectors become saturated, which can lead to flooding. Permeable surfaces help to limit that risk.

The City of Brussels awards a bonus for making sites permeable. This premium aims to encourage the removal of impermeable ground cover (tiles with joints, concrete, asphalt...) and its replacement with permeable material (areas with full soil, gravel, grass tiles, small tiles without joints...) in order to allow rainwater to seep into the soil.

The permeable area must be at least 50% of the total initial area.

Systems with exotic invasive plants are not eligible for this premium. 

Amount of the bonus?

The amount of the municipal premium is set at 75% of the amount for the works with a maximum of 1,000.00 euros.

The premium is increased by 10% for works carried out by social economy companies, tailor-made companies or social integration companies.

The premium is increased by 10% for the construction of permeable zones with plants that are good for biodiversity (native plants, bee plants,...).

A single bonus is awarded per property and per 5-year period.

The intervention of the municipality may not be more than 100% of the investment.

How to apply?

Please fill in the application form and send it within 4 months after the end of the works.

The regulation and form are only available in Dutch and French.
