In this study the quality of Port Sudan water supply was investigated. The investigations included the evaluation of the present water quality through physico-chemical and bacteriological analyses. Further more the water shortage problem experienced by the city of port Sudan was viewed through the revirew of the previous quantitative studies. The results of physico-chemical analyses revealed that the quality of Port Sudan water supply is deteriorated as a result of increased inorganic constituents which exceeded the recommended level in the Sudanese standareds for drinking waters 2002. Tests for chlorine residual showed that the current practice of disinfection is insufficient. The bacteriological tests showed the presence of both fecal and non fecal colform organisms which indicate water contamination. The review of preious quantitative studies revealed that the water table of khor Arba’at aquifer declined due to the excessive drafts. The city requirements for water has surpassed the expected yield of the aquifer, and demands could not be satisfied by the present source. The total demand in 2003 being 71576.6m3/d (26.1x106m3/y) if compared with the amount of water abstracted from the aquifer of 17147.9m3/d (6.2x106m3/y) could show that severely suppressed demand (81%). Conjunctive use of surface and ground water is necessary to meet the present requirements. An alternative sources of water for the present and future is supposed to be either through the utilization of River Nile at Atbara town, River Atbara at Khashm El-Girba or the Red Sea, through water desalination.
