The Beni Haroun water transfer project consists of a 12km-long pipeline (D=2.4-2.6m) to convey water from two dams, Beni Haroun and Boussiaba, to the reservoir of Oued Athmania. Two 90MW pumps are used to pump water to an elevation of 700m. The system also includes a buffer reservoir, a 5.9km-long Djebel Akhal tunnel, and a station for protection against the water-hammer effect. During construction, Geodata studied alternative solutions where the pipeline traverses-unstable slopes and deep-seated landslides (especially at km4 and at km9). As a result, another 1.5km-long tunnel was proposed to bypass the critical landslide areas in addition to slope consolidation works. The system meets the water needs of the six eastern provinces of Batna, Khenchela, Mila, Oum El Bouagui, Constantine and Jijel. It will transfer 300 million m3/year of potable water for urban use and 204 million m3/year of water for irrigation, reaching thirty thousand hectares of new agricultural zones in Telerghma, Chemoura, and Batna-Ain Touta.

Design and construction follow-up of the project; Geological and geotechnical studies of areas with unstable slopes, of the buffer reservoir and of the station for water-hammer effect protection; Preliminary Design of the additional 1.5km-long tunnel with excavation diameter of 4.4m; and specialist assistance, during excavation of the 5.9 km-long Djebel Akhal Tunnel, for accelerating the TBM advancement and for solving the problems associated with crossing of a karstic cavern.
