Effect of Omumm Water Drainage on Noubaria Canal Water Quality and Alexandria Drinking Water Treatments Plants

Ali M Abdullah

Drainage water reuse in Egypt represents a major potential water resource for expanding the cultivated area. El-Noubaria canal irrigates 2.8 million feddans. Alexandria Drinking Water Treatments intakes; mainly El-Noubaria WTP and K.40 WTP take their water from El-Noubaria canal and El-Alamein WTP obtains raw water from El-Nasr canal branched at K. 55 from El-Noubaria canal, which suffers from pollution by agriculture drainage water. A main quantity of such drainage water is coming from Omumm Drain. The present study focuses on the impact of the drainage water of El- Omumm Drain by mixing of its water directly into El-Noubaria canal, which serves agriculture uses and drinking water. Electrical conductivity (EC), was increased in Noubaria canal after receiving point at Nasr canal intake (site III) by 83.9, 109, 118, 81.8%, at Noubaria WTP intake (site IV) by 43.8, 5, 69.5, 43.4% and at K40 WTP (site V) by 66.7, 49.7, 78.6, 67.8% during winter, spring, summer and autumn, respectively due to the attribute of Omumm Drain effluent.. a-BHC, b-BHC, heptachlor, diendrin and endrin, were increased after mixed fresh water with Omumm Drain effluent at Nasr canal intake (km 55), and the average observed values were 2.65, 1.1, 2.4 and 1.3 μg/l for a-BHC, b-BHC, heptachlor and diendrin while endrin not detected during summer and autumn. The ANOVA test showed effects of sites on EC were significant The ANOVA test showed the effect of sites on COD were significant and the seasonal effects on BOD were significant.
