Detached house with infiltration in rain garden and at neighbouring property (Middelfart 7)

The roof trenches are reversed, so the water is diverted to the back garden. Rainwater from the roof, terrace and car port is carried away from the house in a stone trench. This stone trench continues as a grass trench which feeds the water to a rain garden, where 95% of the precipitation is infiltrated.  There is an overflow from the rain garden to infiltration at the neighbouring property. This link is registered in both cadastres.

Haveselskabet has worked in close cooperation with garden owners, Middelfart Municipality and Middelfart Spildevand, as well as NIRAS, to create 7 demonstration gardens in Middelfart. In these gardens, 95% of roof and surface water is managed by means of infiltration in the gardens. The remaining water is fed to a watercourse in the forest behind the gardens.
