SediPipe XL and XL-Plus systems can be integrated into stormwater sewers. This eliminates the boundaries between centralised and decentralised stormwater treatment – the size of the system and the installation location can be selected to perfectly meet your individual needs.

Stormwater treatment systems with the following certificates tested by independent institutes:HTWK Leipzig, IKT Gelsenkirchen, IFS Hanover, TU Delft,  etc.

  • Equivalent to stormwater sedimentation tanks
  • Classification in ATV-DVWK-M 153: System types D21, D24, D25
  • Determination of pass-through values according to ATV-DVWK-M 153
  • Preventing remobilisation
  • Functionality of the flow separator
  • Performance verification and dimensioning using a specifically developed verification procedure according to Section DWA-A 102-2/BWK-A 3-2, (residence time method")

SediPipe XL:

  • sedimentation of coarse and fine particles,
  • retention of light liquids in case of dry weather (spills).

SediPipe XL-Plus:

  • sedimentation of coarse and fine particles,
  • retention of light liquids in case of dry weather (spills),
  • separation of light liquids in case of rainfall (spills).

SediPipe XL-Plus systems are not considered oil separators according to DIN EN 858-1 and must NOT be used for applications provided therein! SediPipe XL-Plus systems are exclusively designed for prevention in case of spills!

SediPipe XL stormwater treatment systems consist of:

  • DN 1000 start shaft
  • DN 600 sedimentation path with lower flow separator, 6, 12, 18, 24 m lengths, (Main conduit with compliance certificate (Ü sign) in accordance with Building Rules List A of the German Institute for Building Technology (DIBt))
  • DN 1000 target shaft with immersion pipe.
