The design of dams and large hydraulic structures made a significant contribution to Sogreah’s international reputation. Artelia’s teams are capable of taking on highly technical and increasingly ambitious projects. Designing and building dams to generate hydropower, control river flows, open up waterways to shipping and create lakes and reservoirs is one of Artelia’s main fields of expertise. The company has honed these skills through working on all types of structure (arch, concrete gravity, RCC, rockfill and earth dams) and the associated facilities (flood spillways, siphons, tunnels, feed chambers and stilling basins).

Artelia is designing and supervising the construction of exceptional structures such as the 160 m high Janneh RCC dam in Lebanon, where it is also supervising works on the Balaa CFRD. In Oman, to avoid any repetition of the catastrophic damage caused by cyclone Gonu in 2007, Artelia is building a series of 12 flood-damping dams, including one 65 m high, to protect the capital city Muscat. Artelia is supervising works on New Fulaidj dam, the 4th to be built since 2007. In Tunisia, Artelia is carrying out studies to raise 4 dams and supervising work on Melah dam, the 6th to be built in the country in 20 years. In Armenia, Artelia was commissioned with the Vedi project, involving the construction of an 80 m high earth dam. In France, Artelia is performing studies to rehabilitate old masonry dams (La Lauch), earth dams (Meaulx) and arch dams (Galens). In New Caledonia, Artelia is also helping mining company Vale to design a tailings storage dam at the Goro mine.
