Underground Water:
The water bearing rock strata comprise the Nubian Sandstone which covers 28.1% of the total area of the Sudan, Um Rwaba series covering 20.5% of the total area and the basement complex which covers 9.1% of the total area. The preliminary surveys of the underground reserve quote the figure of nine md. c.m.
However, there is need for more research to ascertain the actual figures for the reserve and the replenishment rate. At present only about 1.3 md. c.m. of underground reserve are utilized, of which about 450 m. c. m. are used for domestic purposes, while about 850 m. c.m. are used to irrigate about 67.2 thousand hectares.
