The project consisted of enlarging the main wastewater drain to cater for a 50% increase in the wastewater treatment plant’s treatment capacity.
The structure is located under the Promenade des Anglais beach, 4 to 5 metres below the level of the Mediterranean Sea.
It comprises two parallel pipes, each with a diameter of 2 metres, over a total length of 1250 metres. The pipes consist of BONNA RCCPs (Reinforced Concrete Cylinder Pipes) welded together.
They are laid at a slope of 0.25 mm/m.
