The main objective of the project was to shorten the time in which the area from Saint-Gilles to Le Grau du Roi remains underwater. That plan involved the construction of 11 hydraulic stations, five reinforced PSs and one completely new PS, in effect doubling pumping to 45.3m³/sec. This infrastructure investment considerably increases the volume of water that can be drained and significantly reduces the length of time that water remains in overflow areas by draining the land more quickly. Due to the complexity of the project and the number of organisations and suppliers involved, work did not commence on the construction until 2011. Whilst there were many engineering and environmental assessments to be made, the central issue to the success of the project was the hydraulics and their infrastructure. It was here that pump manufacturer KSB took a lead role, having earlier extended the pump station at La Souteyranne/Liviers in 2006 with additional pumps from its Amacan range, and then securing the project contract in 2010.
