Mambilla Plateau. Constructed in 1982, the main Mambilla Dam is a large roller-compacted concrete dam and reservoir at 1,300 metres (4,300 ft) above sea level. From this dam, water is diverted off the reservoir towards the western side of the plateau through four hydraulic tunnels totaling 33 kilometres (21 mi), intercepted by four smaller dams: Nya, Sum Sum, Nghu, and Api Weir.
With plentiful water supply, the reservoir remains full throughout the year. [1] The reservoir provides raw water to the Asejire and Osegere water treatment plants in Ibadan . [ 2 ] The water supply project was completed in 1972, and has a capacity of about 80 million liters per day, of which 80% is used for domestic purposes.
A study funded by the United Nations Environment Programme (UNEP) estimated that the economic value of water in the downstream Hadejia-Jama'are floodplain was US$32.00 per 1,000 m 3, while the value of water in the Kano River Project, irrigated by the Tiga Dam and the Challawa Gorge Dam was US$1.73 per 1,000 m 3, or US$0.04 per 1,000 m 3 after ...
The Tiga Dam is located in southern part of Kano State in the Northwest of Nigeria, constructed in 1971–1974. It is a major reservoir on the Kano River , the main tributary of the Hadejia River . The dam was built during the administration of Governor Audu Bako in an attempt to improve food security through irrigation projects.
