Belgium – Foul-water piping construction work – Collecteur et station de pompage de Petit-Hallet

This project concerns the construction of the collector and pumping station in Petit-Hallet. It falls within the framework of the sanitation project for the Dyle-Gette sub-basin. This project will connect the sewer network of the municipalities of Petit-Hallet and Grand-Hallet to the Wansin wastewater treatment plant. Currently, this wastewater is discharged through approximately twenty outfalls into the Henri Fontaine stream. The purpose of this contract is: - the installation of a wastewater collector and the construction of a pumping station within the municipality of Hannut, as part of the construction of the wastewater network for the Wansin wastewater treatment plant; - the relocation of a drinking water distribution pipeline (SWDE) located on Rue Constant Deville in Hannut. This collector will extend from the outfall located at the intersection of the stream and Rue Mayeur J. Debras to the pumping station situated at the bottom of Rue des Caïades. The discharge pipe will then run up to the Wansin wastewater treatment plant, parallel to the Wansin stream. Several stream crossings are planned.
