Description

With the help of drainage tunnels with a volume of 310 litres, drainage fields can be easily constructed for the infiltration of pre-treated domestic sewage from treatment plants and septic tanks. The tunnels can be used on permeable and slightly permeable soils above the groundwater level by 1.5 m. The ease and simplicity of installing a drainage tunnel ensures fast and safe work. One drainage tunnel weighs only 10 kg and can be carried by hand without the use of mechanical means. Each drainage tunnel can hold up to 310 litres of water per 1 m² of area. Tunnels can be connected in one or more rows to create large drainage fields
