The BECKER 320 l retention and drainage tunnels are designed for the drainage and retention of rainwater collected from the roofs of buildings and from hardened ground areas (terraces, car parks, roads). Rainwater is directed to filtering devices to separate mechanical impurities. It is then directed through drainage pipes to tunnels wrapped in filter fabric to retain and infiltrate the water in the ground. The infiltration tunnels are combined in sets (vertically and horizontally) with sizes depending on the size of the area from which water is collected. The tunnels should be equipped with closing plates, ordered individually. In addition to this product, we also offer the Gama 150L Drainage Tunnel.
