Distribution structures for SediPipe® and SediSubstrator® multi-systems

Compact, Modular, Flexible, Unlimited applications

Special demands, complex local conditions and confined space require professional, efficient and adaptable systems for the treatment of polluted stormwater for small to very large collection areas. Semi-central stormwater treatment turns into central stormwater treatment.

The new distribution structures – distribution shaft and distribution pipe system – complement the tried and tested SediPipe and SediSubstrator treatment systems by FRÄNKISCHE.

They facilitate the inlet and outlet situation of multi-systems and thus create perfect initial conditions for ideal utilisation and function, irrespective of whether two or multiple treatment systems are connected.

Legal provisions and regulations redefine requirements, make them more comprehensive and stricter – from property drainage to urban drainage and motorway drainage or especially critical areas such as filling and service areas. Due to the connection of larger collection areas, there is a consistently growing demand for larger highly efficient treatment systems. The demand for space-saving underground solutions is growing continuously especially in areas where space is scarce.

The distribution shaft and the distribution pipe system allow connecting SediPipe and SediSubstrator treatment systems in parallel and ensure a continuous supply regarding hydraulics and pollution loads (AFS63), also in case of larger water volumes.

With the plastic distribution structures, FRÄNKISCHE offers flexible, modular and pre-assembled solutions with perfectly matched components.

Distribution shaft - System consisting of:

 

  • Distribution start shaft and target shaft

  • Diffusor grill for distribution start shaft

  • Inlet/outlet connection sets for the treatment systems

  • Bypass between start shaft and target shaft

  • Optional shaft extension for start shaft and target shaft

Distribution pipe system - System consisting of

 

  • Distribution pipes and collector pipes in two lengths and different connection variants

  • Inlet/outlet connection sets for the treatment systems

  • Extension pipe for inspection shaft

 

 

 

 

The distribution shaft – compact design, optimised for 2 SediPipe® level systems

The distribution shaft DN 600 has only one design and can thus be used as start shaft and target shaft. The shaft consists of a basic shaft with defined connections and various accessories.

The compact distribution shaft DN 600 is used as start shaft and target shaft with ideally arranged
connection geometry when two treatment systems of the SediPipe level type are installed in parallel.

The diffusor grill, which can only be inserted into the distribution start shaft, does not only retain coarse
particles but also calms down the inflowing water and thus provides for a consistent supply of the
outlets and the connected treatment systems.

After stormwater treatment, the distribution target shaft ensures the connection to the continuing pipe. The integrated bypass between distribution start shaft and distribution target shaft serves as overflow option in case of larger water volumes.

 

Pre-assembled connection sets with different pipe lengths complement the range of products and allow the proper connection between the distribution shafts and the treatment systems.

The distribution pipe system – modular, flexible, unlimited applications

The distribution pipe system DN 800 consists of a modular number of pipe components with 2 or 3 lateral connections each, main pipes and various accessories. Pipe segments closed on one side are used for the end of the distribution pipe and/or collector pipe. Pipe segments with inspection openings allow inspection and maintenance of the system using extension pipes.

The outlet situation can be implemented ideally thanks to the distribution pipe system DN 800 starting
from 2 SediPipe/SediSubstrator treatment systems planned in parallel. Depending on the characteristics of the collection area the connection of multiple treatment systems is allowed.

The distribution pipe is installed horizontally with a gradient of 0 %. The cuffs DN 300 for the treatment
systems installed at equal distances of 1.65 m are arranged centrically on the distribution pipe, not same
level for a consistent supply regarding hydraulics and pollution loads (AFS63).

The collector pipe is installed with a gradient of 1 % in the direction of the junction structure. The treated
stormwater thus flows back into the storm sewer and can be discharged. The inspection shaft integrated into the distribution pipe and/or collector pipe additionally ensures the trouble-free inspection and maintenance of the system.

Connection sets in different pipe lengths complement the range of products and allow trouble-free and proper connections between distribution pipe/collector pipe and treatment systems.
