Detached house with infiltration in lawn and rain garden (Middelfart 1)

Rainwater from the roof is fed away from the house in a pipe beneath the terrace. A grass trench feeds it on to a rain garden on one side, and to a hollow in the grass on the other. There is no overflow, and the system is dimensioned for a 25-year event.

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.
