AbstractDesigning and operating a simulated gravity sewer system had been accomplished in the current research. The design had been provided with aeration system in order to deliver oxygen to microorganisms presented in sewage water. The system had been used in three different seasons in order to investigate the ambient temperature effect on treating wastewater. The results revealed that ambient temperature had a significant role in organic waste degradation powered by the presence of air into sewage pipes and level tanks. Maximum degradation measured in terms of chemical oxygen demand removal (RCOD) was recorded to be 14.28 under 30 OC ambient temperature and 8 hr of treating time. The results recorded from the current system seemed to be promising in terms of self-purification ability of the transporting sewer system.
