The DRAINMAX Tunnel infiltration trench

A solution for local infiltration or attenuation of rainwater and run-off water of sewage plants.

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