This effluent represents a mixture of industrial and domestic wastewater, that collected the large portion of the wastewater from industrial district at right bank of river and some residential quarters.
According to Iraqi standard for conservation of water resources, The suspended solid concentration for stream effluent increased by (122%) and other impurities increase by (16%-29%), Where is according to organic load, the stream effluent classified as weak, for its biological oxygen demand (BOD5) is (56)mg/l as an average. As compared with Municipal wastewater for last previous years, Wady ‘Eqab wastewater impurities were with less concentration levels; These impurities increased by different percentage and some exceeds (34) times. However, The river water is still clear and within the Iraqi standards for conservation of water resources, for the region follow the stream discharge point.
