The project aims at developing the water resources in rural regions located in a number of border provinces in the south of the country, through the construction and rehabilitation of small dams and hafirs (ground reservoirs) to collect and store flood water for a number of valleys with seasonal runoff. The water provided by these facilities will be used for drinking by the nomadic herders and animals in those regions. The project will contribute to the resettlement of nomadic herders, and help avoid conflict between pastoralists and farmers within the borders of Sudan and across the border with the State of South Sudan. It will also contribute to the recharge of groundwater aquifers, reduce soil erosion and desertification, improve the living, economic, social and environmental conditions of the population, as well as reduce the spread of diseases and support stability in the rural regions in the south of the country.


The project, which is expected to be completed by the end of 2013, consists of the construction of three dams, the rehabilitation and heightening of an existing dam, and the construction of 65 hafirs in six provinces: Blue Nile, White Nile, Sennar, South Kordofan, East Darfur and South Darfur. It includes all civil and hydro-mechanical works, and complementary works necessary for the dams and hafirs. It also includes the technical services required for review of studies and design, and for completion of design and tender documents for the project, as well as construction supervision. The following is a description of these components:

  1. Construction of Dams and Hafirs: This component includes all necessary works for the completion of dams and hafirs, and consists of the following:
    1. a. Dams Works: This includes all necessary works to construct three dams and their appurtenant structures; these are Bouk dam in the Blue Nile province, Mallweyah dam in Sennar province, and Abu Jriayes dam in South Kordofan province. The height of these dams ranges between about 4 and 6 m, their crest length between about 450 and 3,100 m, and their storage capacity between about 1 and 2.2 million m3. These works also include the rehabilitation and heightening of Elmeegeines dam in the White Nile province by about half a meter, which will increase its storage capacity from about 3.2 to 7.2 million m3. The construction and rehabilitation works include all civil works of excavation, fill, and concrete for the dams and their ancillary facilities, as well as the supply and installation of hydro-mechanical equipment for those facilities, and water purification units, in order to control and benefit from the water provided by the dams..
    2. b. Hafirs Works: This includes all necessary works to construct 65 hafirs in the beneficiary provinces. The width of the hafirs ranges between 75 and 300 m, their length between 114 and 308 m, and depth between 3.5 and 5 m. The storage capacity of those hafirs ranges between about 40 and 200 thousand m3, with their total capacity reaching about 4.7 million m3. The construction works include all civil works of excavation, fill, and concrete for the hafirs and their ancillary facilities, and diversion dikes to the hafirs as well as sand filters and subsidiary works such as storage tanks and hydro-mechanical equipment..
  2. Technical Services: This includes the consultancy services to review the studies and complete the construction designs and tender documents for the project, to evaluate construction tenders and to supervise the construction of the project. It also includes the use of expert services to review the studies and design of the dams.


The Arab Fund's loan covers about 79% of the total project cost. The Sudanese Government will cover the remaining cost of the project and any additional cost that may arise.
