SediSubstrator XL
SediSubstrator L has been tested and approved according to the strict German DIBt requirements (Z-84.2-11). This facilitates official approval procedures regarding stormwater infiltration systems and, depending on the country, also discharge into surface waterbodies.
e.g. SediSubstrator XL 600/6
Systems of the SediSubstrator XL design are comprised of a start shaft, a target shaft, and a sedimentation path. All shafts are manufactured according to each project’s needs and delivered ready for installation. The shaft base bodies (DN 1000) are completely factory-welded and furnished with a square base plate. The sedimentation path includes several main pipes. The total length of the sedimentation path depends on the system type and varies between 12 m and 24 m. The cartridge elements filled with substrate are located in the target shaft. When installed, inlet and outlet of the system are at the same height and the sedimentation path features a construction-related slope.
SediSubstrator XL 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).
