SediSubstrator L
SediSubstrator L has been tested and approved according to the strict German DIBt requirements (Z-84.2-20). This facilitates official approval procedures regarding stormwater infiltration systems and, depending on the country, also discharge into surface waterbodies.
e.g. SediSubstrator L 600/6
Systems of the SediSubstrator L design comprise a start shaft, a target shaft, a sedimentation path, and an outlet. The shafts are delivered as a three-piece push-fit system and comprise a shaft
bottom with a factory-welded base plate, an inlet and/or outlet set and an extension pipe which can be cut to length individually. The sedimentation path includes one or several main pipes. The total length of the sedimentation path depends on the system type and varies between 6 m and 24 m. The cartridge elements filled with substrate are located in the target shaft. There is a bottom step between inlet and outlet when installed. The sedimentation path features a construction-related slope.
SediSubstrator L is a stormwater treatment system which keeps a permanent water level. Coarse particles are already retained in the start shaft. Fine particles are retained in the sedimentation path. The lower flow separator prevents remobilisation and therefore discharge of sediment also during heavy rain. Dissolved pollutants such as heavy metals and light liquids are adsorbed in the substrate cartridges (adsorption).
