Vives-Eaux dam was initially built in 1928 on the river Seine upstream of Paris and downstream of Melun. It was used to regulate the river level between it and La Cave dam, a sector with heavy shipping traffic that is used by more than 13,500 boats (commercial and pleasure) and 4.5 million tonnes of goods every year.
The original dam, which was still operated manually with a shutter system, no longer met current safety requirements in terms of operation and maintenance.
The project developed by Voies Navigables de France (VNF) aimed to replace this antiquated structure with a more modern dam that will be entirely automated and capable of maintaining a safe water level in order to guarantee river navigation throughout the year. It will also allow water resources (intakes and discharges for cities, industrial players and agriculture) to be managed more efficiently and improve working conditions for the operating staff.
The project to reconstruct Vives Eaux dam on the river Seine included in particular:
- development of a tilting gate dam with three 30 m-wide bays to maintain a 2.71 m head,
- development of a fish pass on the right bank,
- development of a control room on the lock chamber wall and of a plant room on the right bank,
- development of a footbridge over the river Seine including access ramps,
- extension of the jetty,
- demolition of the existing dam and the lock house.
