Assessment of drinking water quality for the city of Port Sudan (source: Khor Arbaat)
Abstract
Port Sudan is the main port and largest commercial center of the Sudan located in semi-arid region. Population estimate in 2010 was about 401,400 inhabitants [1]. The water demand estimated was about 120000-150000 m3/day. Water production from Khor Arbaat is 60,000 m3/day in good years; however, it may go down to 30,000 m3/day in bad years. In general, the overall situation of the city is characterized by regular shortages.
There are three dams (U/G Dam1, SPC Dam2, FR Dam3) structured on Khor Arbaat for water harvesting (2005,2000,1992), siltation represents thegreatest problem to these Dams, accordingly their capacities storage is decreases. Their storage capacities are 16*106, 5*106, and 6*106 m3 respectively, therefore the small capacities of these dams lead to inflation silt in a limited period of time. In the same way the Sea Port Corporation (Dam 2) in the year 2012 was removed by the armed forces of the corps as a result of inflation silting and thickness of silting to 6 meters. Water from Khor Arbaat gets into the transfer system without any treatment. The study is considered baseline study of water in Port Sudan city. All the results pointed the samples of water were not according the Sudanese Standard and Metrology Organization (SSMG) .GIS Arc. Map and Kriging method are used to study the characteristics of water depend on coordinates and samples results.
