Infiltration tunnels are widely used infiltration systems for storm-water and treated wastewater, which ensure the unobstructed equal distribution of water in the soil, even in areas where it has become impermeable.

They have a modular structure and are designed to create a network of underground reservoirs for rainwater management. Their large surface area guarantees fast and efficient release of water into the subsoil.

The system consists of a sequence of connected plastic tunnels and a closure terminal at both ends of each row of modules. Installation is done on a single level, in one or more parallel rows.

The volume of the tunnel depends on the volume of water it collects, always taking into account parameters such as rainfall, soil type, drainage area and loads applied. It is highly durable and thanks to its high durability, it can be installed in areas where heavy vehicles pass through.

Infiltration tunnels can also be used for the underground release of treated wastewater discharged after appropriate treatment in an WWTP.

They are a suitable solution in areas that are not connected to the sewerage network.
