Simulation of Chlorine Decay in Al-Gukook Water Distribution Networks Using EPANET

Aula Sahib Hasan Al-Mamori | Nawar Omran Ali Al-Musawi

Abstract: The approach of the research is to simulate residual chlorine decay through potable water distribution networks of Gukook city. EPANET software was used for estimating and predicting chlorine concentration at different water network points. Data required as program inputs (pipe properties) were taken from the Baghdad Municipality, factors that affect residual chlorine concentration including (pH, Temperature, pressure, flow rate) were measured. Twenty five samples were tested from November 2016 to July 2017. The residual chlorine values varied between ( 0.2-2mg/L), and pH values varied between (7.6 -8.2) and the pressure was very weak in this region. Statistical analyses were used to evaluated errors. The calculated concentrations by the calibrated model were very close to the actual concentrations measured in field at different sampling points for different sampling days.
