The town „Rasseln“ wich is a part of the city Mönchengladbach in Germany wasn’t connected to the sewage network until 2011. The used water had simply been let seep away, which is not permitted.
The NVV (Niederrheinische Versorgung und Verkehr AG), which is responsible for the proper disposal of any sewage, planned the construction of a large mixed water channel. The project consisted of building a large storage channel and pipelines to connect the town of “Rasseln” to the sewer system of the city of Mönchengladbach. In Rasseln sewage water runs into a pumping station and via two pressure pipes into the sewer systems of Mönchengladbach.
To solve this challenge two options were possible:
1. rectangular concrete channel with lining and a dry weather channel
2. Retaining channel of PE consisting of PE- buildings and profiled pipes DN 2000 with dry weather channel
