Objectives:

The project aims at developing irrigated agriculture and increasing agricultural production in the Republic of Sudan, through irrigation of about 51 thousand hectares (about 121 thousand feddan) of agricultural land in the Roseires region. The project will contribute to the generation of electrical energy from the hydroelectric power station included in the project, the improvement of the economic and living conditions of the farmers in the project region, and the provision of new employment opportunities.

Description:

The project, which is expected to be completed by the end of 2021, consists of the following main components:

  1. Main Water Conveyor Works:These include the execution of all civil and hydromechanical works to construct the main conveyor, which consists of an earth canal with a length of about 46 km and a maximum discharge capacity of 300 m3per second. The works include the excavation, fill, concrete and other works necessary to construct the main conveyor and associated structures such the regulators, water intakes and outlets, as well as the supply and installation of all hydromechanical equipment and devices, and the monitoring and measurement systems necessary for water control.
  2. Irrigation and Drainage Networks Works:These include the execution of all civil and hydromechanical works to construct earth canals for irrigation and drainage required to irrigate about 51 thousand hectares of agricultural land in the Roseires region. The total length of the main and minor irrigation canals is about 485 km with a maximum discharge ranging between 0.6 and 123 m3per second. The total length of the main and minor drainage canals is about 610 km with a maximum discharge ranging between 2 and 54 m3per second. The works include the excavation, fill, concrete and other works necessary to construct the irrigation and drainage canals and associated structures such the water intakes and outlets, as well as the supply and installation of all hydromechanical equipment and devices, and the monitoring and measurement systems necessary for water control.
  3. Water Intake and Hydroelectric Power Station Works:These include the execution of all civil, hydromechanical, electrical and mechanical works necessary for the water intake in the Roseires dam, and the construction and equipment of a hydroelectric power station with an installed capacity of 55.5 MW. The works consist of the supply and installation of pipes to carry water from the intake to the power station with a diameter of about 5 m and a total length of about 890 m. The works also include the supply and installation of 3 Kaplan turbines, each with a rated capacity of about 18.5 MW under a discharge capacity of 100 m3per second at an average head of 21 m, the generators, transformers, breakers and all required equipment and devices, the measurement, protection and control systems, as well as a transmission line required to connect the power station with the existing substation in Roseires dam.
  4. Technical Services:These include the consultancy services necessary to review the studies, prepare the detailed designs, execution drawings and tender documents, assistance in evaluation of bids and construction supervision.

Financing:

The Arab Fund’s loan covers about 41% of the total project cost. The Kuwait Fund for Arab Economic Development contributes to the financing of the project with a loan of KD 25 million (about 17%). The Sudanese Government will cover the remaining cost of the project and any additional cost that may arise.
