The city of Oelde is planning the construction of a new wastewater pumping station including an associated new da 280 pressure pipeline (DRL) for transporting the wastewater from the district of Lette in the north of the city of Oelde towards the sewage treatment plant southwest of Oelde.

The new construction of the pumping station and DRL will be divided into the following construction phases:

- Pressure pipeline and sewer, section Lönsweg, station 0+025 to 0 +175

- Pressure pipeline station 0 +000 to 0 +025 and 0+175 to 6+934,

New construction of the waste water pumping station

This tender is about the scope of services pressure pipeline station 0+000 to 0+025 and 0+175 to 6+600, new wastewater pumping station

The present case concerns the scope of services pressure pipeline station 0 +000 to 0 +025 and 0+175 to 6+600, new waste water pumping station

This mainly includes the following services:
