Assessment method of urban domestic sewage treatment plant-network integration based on current drainage management

ABSTRACT The main hindrance to implementation of domestic sewage treatment plant-network integration in China is the separated assessment method. The assessment method of plant-network integration links payment for sewage treatment to incoming pollutants, and payment for maintenance of the pipe network to the concentration of pollutants in incoming water. It helps establish an interactive link between the city and district, and motivates operation and management stakeholder groups. The method contains index system formulation, target value determination, assessment payment plan specification and city-district payment proportion clarification. It provides a solution for the current drainage management by promoting plant-network integration.
