The INFIL300 (Infiltration Tunnel 300) is a strong and durable leach drain (also referred to as an arch trench drain) for wastewater treatment systems (both primary and secondary).
The INFIL300 has been designed to be used in private and rural areas using one or more modules and two endplates and can be extended to your required length.
Ergonomically designed and engineered with ease of use in mind, a single module only weighs 11kg. This unit requires some additional components such as End Plates and Geotextile material. There are also non-required extras such as an Inspection Hatch, Deaeration End and a Choke Drain.
