Abstract
This research is about the sewer system and its deterioration condition in Iraq generally. It causes many different problems on the environmental harm to humans. The researchers present the impact caused by sewage in the case of fully manholes or leakage to the soil of the including sewage networks in general. The study was circulated to the reality of Iraq as a result of the suffering of the Iraqi citizen provided by the networks where the subsurface water of Manholes and leakage into the soil, in addition, to causing air pollution and the environment odor due to carry the gases of methane and hydrogen sulfide and CO2. The Research considered Al-Shorja market as a case study, The researchers theorized to consider the overflowing Manholes at a selected site(The street blockaded between the holding of the Christians town and the Arab market) as a sedimentation tanks because of their failures as manholes. A mathematical study was done to determine the efficiency of sedimentation at these manholes and the most efficient geometry shap to remedy the situation if not allocated a budget to change networks in the near future, It was found that the efficiency of sedimentation are poor under the degree of 50% and this means that the proportion of sediment and organic materials at high rates, bursting to the surface and cause many environmental problems contained in the body of research. this research has provided a number of proposed solutions to rid the streets and may be circulated to all areas affected by the situation.
