DRAINMAX - Tunnel Infiltration Systems Brochure

The basis of the DRAINMAX Tunnel infiltration system is our 1.6 m³, large volume, light plastic trays that create 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 saves significant costs on laying complex piping systems. You can also use the DRAINMAX tunnel system for infiltration of effluent water from sewage plants.
