This paper describes a project to integrate EPANET, Giris and SCADA to assist water engineers in assessing the water distribution system in city S. The integrated system simulates the flow and concentration of chemical contaminants in municipality's water distribution system. The integrated model is a powerful tool for routine planning and emergency response. The capabilities of the model can greatly assist in the decision making processes for network asset inventory, rehabilitation requirements, and financial planning. The system was tested using the S City database composed of approximately 13219 junctions and 14832 pipes whose diameter not less than 300 mm.
