In the small, northern French town of Hazebrouck, approximately 40 km south of Dunkirk, the construction company Eifrage TP Nord (Wattignies/Lille) is currently building a rainwater storage basin with a capacity of 10,000 m³. Their customer is the municipality of the township numbering 21,000 inhabitants. The basin, sunk 12 m deep, has a diameter of approximately 35 m and will relieve the strain on the town's sewage system after heavy rainfall. It is only worthwhile to use truck-mounted concrete pumps with a large working range and flexible boom technology here.
