Risks Management for Liquid Waste Disposal Area in the Khartoum Refinery-Sudan

Abstract

This study focused on evaluating the procedures of risk management associated with disposal of oil wastewater at Gaili area, Khartoum north, Sudan. Approaches used in this study. Research tools conducted were Interviews, sampling and analysis report interpretation, aerial photographs analysis & topographic modeling analysis for the Gaili area. The study of risk management is conducted for oily wastewater disposal at Gaili area and analyzed current activities of the Khartoum refinery, petrochemical plant, Garri power plant, fuel terminals and the gathered data. The Study found that the selection of the site of the wastewater area was improper, the construction specification of the oily waste water area was not following the international standards and the final disposal of the generated sludge is not following the international environmental conventions. The study found that the wastewater disposal area might have huge probability of impacting the surrounding environment, and severe impacts will be on the groundwater, soil, surrounding water courses and the quality of the air in Gaili area will be affected by oily wastewater disposal. The study recommended establishing an environmental monitoring program for the wastewater activities, and to conduct an environmental site assessment of the area and adopt the remediation plan developed according to the developed data, to construct a new sedimentation lagoon according to international standard and to provide a bioremediation unit to treat the generated sludge.
