MANAGEMENT OF WASTEWATER TREATMENT PLANTS IN SUDAN
In Khartoum State the two wastewater treatment plants are of capacities at present of 40000 m3/d & 17000 m3/d in Khartoum city & Khartoum North respectively. Previously, the plant in Khartoum city was a conventional attached growth process (trickling filters) which had been replaced by waste stabilization ponds with the treated effluent was being reused for restricted irrigation as a green belt in Khartoum South (Eucolyptus Species). At present the green belt in Khartoum South is not in existence & the land was converted to residential areas. Treated effluent of the plant is at
present partly directed to surface water creating potential environmental hazards.
In Khartoum North, the plant has been upgraded to a conventional activated sludge process (Sequential Batch Reactor)
& the treated effluent of 17000 m3/d is now reused for restricted irrigation in a sub-urban district in Khartoum North at a distance of about 20 Km (Hattab district). For the small decentralized wastewater plants in Khartoum State & other States of the country, the treated effluents are utilized locally for landscaping purposes.
A sewerage master plan is recently launched in Khartoum State in order to put a strategy to improve the situation of
this important infrastructure sector.
