It is with 1.6 m³ a large volume and light plastic tray system that creates a hollow space in the soil. The rain water can be directly retained at the source and will infiltrate through the open soil and side holes. It is also possible to restrict the water flow to the stormwater pipe only. This technology saves significant costs on laying complex piping systems. The DRAINMAX tunnel system can also be used for infiltration of effluent water from sewage plants.
