Application of hydraulic model in urban sewage network transformation

InfoWorks ICM can be used to build sewage system hydraulic model and realize the simulation of sewer pipe network's operating condition.If the calculated values and the measured data meet the checking accuracy requirement,transformation programs can be validated by the hydraulic model to assess the feasibility.The paper takes the diversion project of Datansha sewage system-Shijing sewerage system in Guangzhou as the research object.By using the computer simulation technology,the hydraulic model is built to assess and analyze the condition of trunk pipeline running overload,sewage overflow and plant operation load,which may provide theoretical basis for feasibility analysis of transformation program.
