Beni Haroun Mila Dam
The Béni Haroun Dam is located in the wilaya of Mila, approximately 40 kilometers north of the city of Constantine and 350 kilometers east of Algiers in the north-east of Algeria on Oued Kébir.
The dam is located at the upstream end of the Béni Haroun gorge, approximately 4 km from the confluence of Wadi Rhumel and Wadi Endja. The height of the dam is 118 m on the foundation and its length at the crest is 710 m. The total volume of the reservoir is 997 million m3, allowing the regularization of approximately 435 million m3 per year.
This dam is intended to supply drinking water to the city of Mila and Constantine, as well as the irrigation of approximately 30,000 hectares in the plains of Teleghma, Chemoura and Tafouna at a rate of 228 million m3.
The work constitutes the key to the project of transferring water resources mobilized by the Béni Haroun dam to the six (06) Wilayas: Batna, Khenchela, Mila, Oum El Bouaghi, Constantine and Jijel.
The free threshold type surface evacuation is integrated into the body of the structure, in the central part of the valley; with a total length of 122.40 m and a maximum flow rate of 16,000 m3/s.
The diversion structure is made up of two concrete galleries with a diameter of 8m and allows a maximum flow of 3500 m3/s.
Three galleries were built at the bottom (100 m NGA at the lowest), at 140 m NGA and 175 m NGA.
With intermediate galleries; the lower gallery was used as an injection gallery to create an injection veil. These galleries collect the drainage flow.
The construction of this dam began in 1996 and completed in 2002 and the impoundment in 2003.
