Pumps for Europe’s biggest wastewater project
The Emscher Wastewater Canal (AKE), the centrepiece of the project “Wastewater Free Emscher”
In the Ruhr Area between the cities of Dortmund and Dinslaken, parallel to the Emscher river, the new 51 km long Emscher sewer has been built to receive the wastewater of 2.26 million
residents and industry. As the largest water management construction project in Europe, the Emscher, formerly used as an open sewer, will in future be free of wastewater. Three huge
pumping stations in Gelsenkirchen, Bottrop and Oberhausen as well as more than 100 shaft structures are needed to operate the gigantic sewer. The impressive shafts have diameters of
between 7 and 22 m and are between 10 and 40 m deep.

The pumping stations contain individual wastewater chambers that have to be pumped over or emptied as needed. For this purpose, two space-saving vertical Turo® Vortex pumps are
installed in each of the three pumping stations. Since the residual water usually contains a high content of solids and fibres, these pumps, with open spherical channel of 180 mm (Gelsenkirchen and Bottrop) or 100 mm (Oberhausen) and a fully recessed vortex impeller, are ideally suited. The pumps are all equipped with a Eurodyn® hydrodynamic shaft seal, which operates free of friction and wear and is characterized by very high operational reliability.

The Emscher sewer, which runs parallel to the Emscher for about 50 km, collects the wastewater along its route.
The pumping stations are needed to raise the wastewater coming from the eastern catchment area to a higher level, from where it reaches the
wastewater treatment plants of the Emschergenossenschaft.
Emile Egger is particularly pleased to contribute to this exceptional construction project.
