Description

Reviews

The SuDS Infiltration Tunnel has been designed for the use in underground applications as a means to efficiently create a soakaway or attenuation storage.

Each single unit provides a storage volume of 300l. This volume can be doubled if 2 units are connected into a complete tunnel formation.

Simply add the endplates (2No.) to provide a complete unit which allows a number of standard connection ports (110, 200, 300mm). Geotextile surround and dearation end are also required.

Consider the soakaway infiltration tunnel kit for all items to create a drainage field or soakaway.

Include upstream filtration/access to allow inspection and maintenance.

Include an aeration port to allow instant evacuation of air if surcharging of the upstream pipework is anticipated.

The system which consists of one or setveral tunnel modules and two end plates can be extended at will
The laying is realized in one or more lines of the same level
As the weight of one module is only 11 kilos, the handling of the Infiltration Tunnel is excellent
The surface beyond the tunnels is lorry-bearing which offers versatile possibilities
The infiltration tunnel can be loaded permanently up to 59kN/sqm and thus is also suitable for lorry-bearing
5 years warranty
