Worldwide about 785 million people are denied the right to clean water and 2 billion people lack access to adequate sanitation. It was estimated that Sub-Saharan Africa region will reach the water and sanitation targets of the MDGs’ only by 2040 and 2076 respectively. Sanitation and water quality associated problems are evident throughout Sudan since waterborne diseases make up 80% of the reported diseases in the country. In Sweden the adoption of the sewage system resulted in a decrease in diseases linked to latrines. In Sudan the system used to serve about 28% of the capital in 2007 and is being expanded to satisfy the escalating demands. Adoption of treated wastewater reuse together with other measures is of great potential to conserve fresh water resources and alleviate the present conflict on Nile water resources. The practice was to use treated wastewater for forestry production in the former Green Belt. An alternative use for fodder production is quiet feasible if the safety measures were rigorously followed. Due to the conversion of the Green Belt into residential areas the amount reused in agriculture and forestry is reduced to only 1/3 and the rest conveyed to the White Nile. This practice created a huge pollution potential to the river and nuisance to the residents along the canal. To curb dust storms and to rehabilitate the desertified lands of the area the paper recommends construction of irrigated forests around each of the three towns constituting the capital.
