Renovation Main Sewer Oss Construction Team (Phase 3)
The tender concerns the renovation and 'relining' of a 1,650 m² section of a concrete culvert that carries wastewater from Oss to the RWZI Oijen. The pipeline, cast in 1967, has internal dimensions of 2,450 x 1,650 mm and a wall and floor thickness of 250 mm. The free fall runs over 4.2 km with a height difference of only three meters, resulting in a very small gradient. After renovation, the original capacity and free flow must be maintained. The project will be carried out via an open procedure. The contracting authority is Waterschap Aa en Maas. The works require a precise finish, material selection resistant to long-term exposure to wastewater, and minimal interruption of the water flow.

The work concerns the renovation and 'relining' of a section (approximately 1,650 m¹) of a large concrete discharge culvert that transports wastewater from the city of Oss to the rwzi Oijen. This discharge pipeline is constructed as a concrete culvert, cast in situ, and dates from approximately 1967 with internal dimensions of 2,450 x 1,650 mm (WxH) and a wall and floor thickness of 250 mm. The wastewater is led under free fall, therefore without a pumping station, from the takeover point at the Brabantlaan to the rwzi Oijen. The free-fall main sewer lies almost in a straight line and has a pa
