News — Stormwater retention

DRAINMAX Tunnel. A solution for local infiltration / attenuation of rain-, storm water or run-off from sewage plants. With DRAINMAX, rain or storm water can be directly retained at the source and either infiltrate into the ground or attenuated and slowly released into the storm water or sewage system. Therefore easing the pressure on the pipework during high rainfall events. The system can be completely cleaned thus no loss of infiltration capacity or silting up.  Huge storage capacity (1600 ltr/segment), minimum space requirement and quick installation of the DRAINMAX Tunnel are a few advantages of the system.

Infiltration and Attenuation Systems Rainwater Infiltration - Complete solutions for trench and trough-trench infiltration Trench System Trench systems are ideal when the surface above the infiltration system shall be usable, parking, playground etc. Trough-Trench System The polluted rainwater is cleaned via bio-active soil and seeps into the underlying trench, where it is stored short term to infiltrate. Rainwater Retention / Attenuation - to ease pressure on public drainage infrastructure Trench System Rainwater is filtered through a sedimentation/ filter shaft, then stored short-term in the in-ground trench and slowly released via the throttle outlet. The system can remain open at the sides and...
