Detached house with infiltration in lawn and rain garden (Middelfart 3)

The roof trenches are reversed, so the water is diverted to the back garden. 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 along an existing garden to a rain garden. A drain beneath the trench allows rainwater to be fed out into the gardens along the trench as well. The rain garden has an overflow to the river in the forest. A discharge permit has been granted for the overflow.

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.
