Assessment the performance of water treatment plants in Baghdad governorate using GIS

Abstract

Water is essential to a solid society and feasible growth. Water demand is increasing due to increasing population density, fast urbanization, industrialization, and agriculture. The Tigris River supplies drinking water to nine water treatment plants in Baghdad, therefore monitoring their chemical and physical properties is important. 15 parameters (pH, Tur., TDS, EC, TH, Alk., Ca+2, Mg+2, Fe+2, Cl-, SO4-2, NH3, NO3-, NO2-, PO43) from treated water were measured in 2009 and 2019 and compared their values to Iraqi and WHO findings. The results show The value of turbidity in 2009 at center 8 was 11.2 which is exceeded the allowable limits this is might be absent the coagulation process, as well as the high concentration of the turbidity in the Tigris river at that time, meanwhile the value of alkalinity, was 159.75(mg/l) in 2019 at center 2 . however the remaining results were inside as far as possible.
