SediPipe Level
SediPipe level is a stormwater treatment system for polluted stormwater runoff, e.g., from traffic areas. The system separates washed-up particles and light liquids (oil) from stormwater and reliably retains these materials in the system, even in case of spills in dry weather.
SediPipe level systems have been designed for different applications. In addition to being installed upstream of a waterbody, this system can also be installed upstream of a Rigofill inspect storage/infiltration system or a pipe swale. The significant characteristic of SediPipe level is its same-level inlet and outlet allowing for very shallow installation depths. SediPipe level comprises a start shaft, a target shaft, the sedimentation path, and additional accessories such as extension pipes, sediment trap and DOM sealing ring. The sedimentation path includes one or several main pipes in diameters 400, 500 or 600 with an installation length of 6 m each. The lower flow separator preventing remobilisation of sediment is located in the sedimentation pipe. The total length of the sedimentation path depends on the system type and varies between 6 m and 12 m. The sedimentation path features a construction-related gradient when installed.
SediPipe level is a stormwater treatment system which keeps a permanent water level. Sedimentation initially retains the coarse particles in the start shaft. The downstream sedimentation path retains fine particles. The flow separator prevents remobilisation and therefore discharge of sediment during heavy rain. The immersion wall in the target shaft retains fuel and oil in the system in case of spills.
