Following the floods on 6 and 8 September 2005, the City of Nîmes applied for extraordinary state aid to speed up the implementation of the flood protection plan.
The project is part of the ‘Cadereau’ flash-flood channel programme More specifically, the development work focuses on two tributaries of the Vistre:

• The Vistre de la Fontaine flash-flood channel, including the construction of the Tour de l’Évêque basin.
• The Uzès flash-flood channel, including the excavation of the Magaille basin.

Crossing Nimes along the east-west axis, the future line T2 Tram-Bus represents a major stake for the town. As a backbone for the transport network with 26 stations, 13 hybrid buses and a busway that lengths 11.5km, the line improves the existing urban landscape, promotes social and urban cohesion between the districts and the heart of the town, and helps to develop new ways of living in public spaces. Ingerop leads the operations study, traffic flows and handles hydraulic modelling, regarding the historical constraint of Nîmes with high flood risks.
