Research on the Corrosion of Sewer System Pipelines from Domestic Wastewater

Zhaohui, Chen / Qiang, He / Wentao, Yan

This paper studies the corrosion mechanism of domestic wastewater on concrete or reinforced concrete pipelines by analyzing the sewerage sampled in different sites and at different times in the sewer pipeline in Chongqing, Peoples Republic of China (P.R. China). The main factors affecting the durability of the concrete pipeline are corrosion of the reinforcement in the concrete caused by hydrogen sulfide and acidic wastewater. Some preventive measures for protecting the concrete and reinforced concrete pipeline are also proposed.
