Detached house with infiltration in rain garden (Middelfart 2)

The roof trenches are reversed, so the water is diverted to the back garden. An existing container collects roof water from an outbuilding and pavilion. Rainwater from the roof is fed away from the house in a pipe beneath the terrace. A winding trench made of sett paving feeds the water to a rain garden, which also receives water from the neighbouring property. 95% of precipitation is infiltrated. The rest runs out into the river in the forest behind the garden. The connection to the neighbouring property is registered in both cadastres, and there is discharge permit for the river.

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.
