Renovation of manhole covers main sewer Bergen op Zoom
The Municipality of Bergen op Zoom is requesting the renovation of 57 manholes within a 3 km long concrete ø1500mm main sewer, installed in 1972. The manholes are largely inaccessible, unlocatable, or can no longer be properly sealed, making inspections and maintenance difficult. In an earlier phase, the manholes were made accessible again, but various defects were identified during execution. The tender focuses on replacing manhole covers, repairing defects, and ensuring optimal accessibility for future inspections. The works include removing and replacing old covers, repairing damaged manhole walls, constructing access roads, and implementing a demountable, specifically designed manhole cover in collaboration with TBS Soest. The goal is a sustainable, inspection-friendly main sewer that meets current safety and environmental requirements.

During the preparations for these projects, it appeared that most manholes had become inaccessible, unreachable, or even unlocatable over time. The manholes that were locatable and accessible could no longer be adequately sealed. In the project ‘replacement of manhole covers main sewer’, all manholes were made accessible and reachable again. For example, access roads were constructed in various locations. In collaboration with TBS Soest, a specific manhole cover has been developed that is intended to facilitate better func
