Ahvaz Water and Sewerage Network EOP project in terms of environment and emergencies

Document Type : Original Article



In the present article, the existing problems in the water and sewage system of Ahvaz city have been studied. In this regard, all components of the system have been evaluated and their vulnerability in the event of unexpected events has been considered. According to the studies performed, among all the unexpected accidents, floods can cause the most damage to the water supply and sewerage network of Ahvaz. In this study, the system was identified for all contingencies. Finally, based on system deficiencies, operational problems, and network hardware, an emergency plan (EOP) was proposed to deal with anticipated accidents. In this project, the issue of training all personnel from operators to senior managers was examined and the program was proposed. According to the studies performed and also the analysis of the performance of different accidents and predicting the percentage of destruction of each of them on different parts of the water distribution and transmission network and considering the long life of most water transmission and distribution pipes in Ahvaz and severe decay in some parts Earthquake was identified as the most devastating event that could happen to the network and various parts of the treatment plant and water storage sources, followed by floods and finally fires as the third priority. This project is planned to cooperate with the staff of Ahwaz Water and Sewerage Company in response to emergencies of water and sewage system. The application and success of this program depends on the accuracy of its contents. This program is an application tool that must be maintained and regularly updated due to changes in the water and sewage system.
