Detached house with soakaway and rain garden infiltration (Brøndby 12)

In the front garden, the roof water is fed via a sludge trap to a soakaway with an overflow to the lawn. In the back garden, the roof Water from an extension is fed to a rain garden. The roof water from the back of the house is fed via a sludge trap to a soakaway positioned beneath the rain garden. Venting of the soakaway also acts as an overflow from the rain garden to the soakaway.

The residential road Lindevang in Brøndby Strand forms a starting point for a demonstration project. 15 homeowners have diverted their rainwater from the community sewage system in order to relieve the load on the sewage system with a combination of rainwater gardens, hollows in lawns and soakaways.

The purpose of the project is to develop solutions in respect of civil engineering and regulatory procedures, and also to expand on experience.

This project is part of a collective project in which the road runoff from Lindevang will also be diverted and a Plan B solution for the road and gardens is being examined.

The project is designed for a 5-year rainwater event. A total of approx. 2,200 m2 of roof surface area has been diverted.

Statement by the contact (advisor/consultant/researcher/producer/utility company/municipality):
"Together with the other initiatives in the area, the project will hopefully allow us to avoid having to extend our sewer systems as much as we would have had to have done otherwise. At the same time, it is reasonable for people to get something out of the rainwater locally instead of sending it all the way here to the waste water treatment plant," says project manager Søren Hansen, Spildevandscenter Avedøre.

Project owners: Brøndby Kloakforsyning, Spildevandscenter Avedøre and Brøndby Municipality
Advisors: Orbicon and Haveselskabet
Contractors: Per Aarsleff and Lars Voss
