FRÄNKISCHE offers a wide range of separators for the filtration and removal of mineral oils, sediments and heavy metals from stormwater.

SediPipe L systems can be integrated and retrofitted into any stormwater drainage network. This helps eliminate 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. SediPipe L boasts the greatest possible construction site flexibility because connection angles and installation depths can be adjusted on site. Furthermore, as the SediPipe L system is a modular solution, you can add additional units (connected via a manifold arrangement) to handle the modelled flow rates and treatment performance targets.

SediPipe L cleans heavily contaminated stormwater by allowing suspended solids to settle (sediment) below the flow separator. SediPipe has a very high separation performance of 86 %, removing suspended solids measuring < 0.06 mm from the stormwater. Fine sand and coarse sediment are removed 100 % in the SediPipe system.


The function of SediPipe is effective and innovative. The innovation comes essentially from the patented grids developed specially for this purpose – the flow separator. Its special structure prevents circulation and short-circuit flows.

Ease of installation & traffic loads

SediPipe L plus is delivered from stock. Thanks to the innovative telescopic design, you can select the right connection height and angular deflection on site. Because there is no difference in height between inlet and outlet, SediPipe L plus can be easily installed, even in an existing pipework system.

As standard, SediPipe L plus can withstand heavy traffic loads.

Easy Maintenance

The service interval* is: 3 years A standard vacuum truck with spray head needs roughly 1 hour for complete cleaning and camera inspection of the SediPipe.

* A unique feature is that the service interval can be exactly determined after the 1st year of operation by means of a camera inspection.
