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.
