Detached house with infiltration in lawn and rain garden (Middelfart 5)

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. The terrace has a permeable surface. A grass trench feeds the water to a hollow in the lawn (campfire area), where it is infiltrated. There is overflow from the campfire area to the river in the forest behind the garden. A discharge permit has been granted.

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.
