French water utility seeks dam safety improvements to Graon Dam

A French municipal water supplier seeks bids to perform dam safety improvements to Graon Dam on the Graon River in France’s Vendee Department. Bids are due March 12.

The municipality of Greater Nancy took bids in February for dam safety engineering of dams on the Meurthe River in France while France’s Somme Department took bids in January to rehabilitate three dams on the Somme River.

In the current solicitation, inter-community water supply agency Syndicat Intercommunal d’Alimentation en Eau Potable (SIAEP) Plaine et Graon seeks bids to carry out dam safety improvements intended to increase the ability of Graon Dam to withstand extreme flooding. Graon Dam was built in 1972 to supply a water treatment plant just downstream.

Work is to include construction of a new spillway on the left bank, reconstruction of the dam crest, creation of a stability berm on the downstream slope and storm drainage, rehabilitation of the right bank spillway and stilling basin, and improvement of monitoring equipment.

Tender documents may be obtained from Cecile Le Bras, (33) 251248220, E-mail: marches@vendee-eau.fr, at the address below. Bids, in French, are due by noon March 12.
