Stormwater Treatment

Reliability and protection of water bodies

Collected stormwater can be polluted with different materials, e. g. coarse dirt, mud and light liquids from road traffic or industrial facilities. These materials can cause malfunctions of stormwater management systems such as infiltration swales. In addition, they can pose a threat to downstream water bodies or the groundwater. M 153 bulletin.

Innovative alternatives

Conventional systems are often open concrete stormwater sedimentation tanks according to DWA-A 166. They require a lot of space and a considerable excavation depth. FRÄNKISCHE provides a comprehensive range of alternatives. SediPipe replaces e. g. stormwater sedimentation tanks and provides great advantages for construction and later land use thanks to its low excavation depth. The system does not consume any surface space. The land can be used for car parks or roads and tracks.

SediPipe L Plus

SediPipe L plus has been equipped with a second upper flow separator for oil separation. The patented technology allows the system to perfectly imitate the oil separation function. This way, the system guarantees preventive water protection in case of oil spills also during heavy rain.

The systems can be integrated into stormwater sewers thus eliminating the boundaries between centralised and decentralised stormwater treatment.  – The size of the system and the installation location can be selected to perfectly suit your needs.

  • Sedimentation of coarse and fine particles
  • Retention of light liquids in case of dry weather (spills)
  • Separation of light liquids also in case of rainfall (spills)


SediPipe L plus systems are no oil separators according to DIN EN 858-1 and may not be used for applications provided therein!
SediPipe L plus systems have been exclusively designed for prevention in case of spills!

SediPipe L plus stormwater treatment system consisting of:
  • Start shaft and target shaft DN 800 with extension pipe DN 600
  • Sedimentation path DN 600 with upper and lower flow separator, 6, 12, 18, 24 m length
