A solution for managing infiltration or attenuation of rainwater or effluent from septic tanks and sewage treatment systems.

The DRAINMAX Tunnel system is a light-weight plastic tray system that creates a hollow space in the soil where rain water can be retained at the source and released slowly or be allowed infiltrate through the open soil base and side holes. The system has DIBt®-approval a 1.6 m³/m length.

This technology saves significant costs on laying complex piping or culvert systems. You can also use the DRAINMAX tunnel system for infiltration of effluent water from septic tanks or sewage plants.

The system can also be supplied with monitoring equipment that allows the customer to monitor infiltration/attenuation performance and to determine when the system requires cleaning.
