Infiltration tunnel for rainwater tank Unground R-Drain 150

The construction is reinforced with sturdy ribbing and a horizontal lug (the so-called fin) at the bottom of the base which prevent the tunnel from collapsing when covered with a layer of ground. The inlet mounting lug on the front and rear wall of the tunnel allows the installation of a sewage pipe to supply waste water and rainwater, or a combination of several tunnels into a single drainage line. Inside the tunnel there is a 110 mm diameter drainage pipe, which allows the waste water to spread evenly over the entire length of the tunnel. To ensure adequate ground oxygenation under the drainage tunnel, connect the vent pipe to the final tunnel in the drainage line, take it above ground level and close with an aeration head. The tunnels are connected with PVC-U sewer fittings and drainage pipes which are also made of PVC-U.
