Ihlienworth stepped pumping station
The Ihlienworth step pumping station, like the Otterndorf estuary pumping station, was also built in 1928/29 and is located approx. 17 kilometers away.
There are vertical shaft underwater pumps in the pumping station and are still there today. The performance of 2 x 8.00 m³/s is achieved with a delivery head of 1.35 m or 2 x 10 m³/s with a delivery head of 1.00 m.
After pump 1 of the pumping station in Ihlienworth was completely overhauled in 2007, pump 2 was completely overhauled in 2008 and has been fully operational again since the winter of 2008/09.
Task of the creative works
The difficulty in draining water in the lowlands - for example in the coastal area - is natural. The terrain lies up to 2m below the mean tidal high water. The distance to the main receiving water (here e.g. the Elbe) is long and the gradients are small. Pumping stations have therefore been built for these lowland areas, which pump the water into the main or receiving waters of the next elevation. A water and soil association distinguishes between different types of pumping stations, depending on the task it has to fulfill.
