The Upper Atbara and Setit Dam Complex is a twin dam complex comprising Rumela Dam on the Upper Atbarah River and Burdana Dam on the Setit (Tekezé) River in eastern Sudan. The site of the twin dam is located about upstream from the junction of the Atbarah and Setit rivers and about south of the Khashm el-Girba Dam. Construction began in 2011 was expected to be completed by March 2016.[2] The 320 MW dam was inaugurated by President Omar al-Bashir in February 2017, with final stages completed later that year.[3]

Design

Rumela Dam on the Atbarah is tall and Burdana Dam on the Setit is in height. The two dams are connected and have a total length of . The twin dam complex has a joined reservoir with a storage capacity of about 3.7e9m3 of water.[4] The maximum filling level is above sea level. The project includes the construction of hydropower stations on both Rumela and Burdana dams with a total installed capacity of 320 MW, and annual firm energy of . [5]

Project objectives

The project was announced in April 2010 with the aims of supporting the development of eastern Sudan by providing irrigation for local agriculture, supplying potable water, and power generation. The project also aimed to increase agriculture production in the New Halfa area of Kassala currently irrigated by the Khashm el-Girba Dam, and the development of new land consisting of in Upper Atbara.Additionally, the dams are expected to provide flood-protection measures along the river banks by regulating the river flow in the project area.

Project costs

The total cost of the dam complex is estimated at $1.9 billion, of which $838 million for the construction of the dams is from the China Three Gorges Corporation (CTG) and its overseas project-contracting subsidiary, China International Water & Electric Corporation (CWE).[6]

In addition to the project implementation costs are hydroelectric and electric costs, technical and consultancy service costs, land-owning and population resettlement costs, and project implementation management and supervision costs by Sudan's Dams Implementation Unit (DIU). The consultant for the project is the French company Sogreah, which also designed and supervised the implementation of the Khashm el-Girba Dam during the 1960s. The Rumela and Burdana dam designs were revised by the German Company Lahmeyer International, the same company that allegedly revised and supervised the design of the controversial Merowe Dam.

Archaeology

Archaeological surveys were undertaken in the area to be flooded by the National Corporation for Antiquities and Museums during the summer of 2011.[7]
