Abstract:With the increase of drainage facilities and the gradual expansion of the service scope in Shanghai, the main body responsible for the management of drainage facilities is decentralized under the municipal and district management systems, and the scale effect has not been fully realized. There are a large number of regional drainage households in Shanghai, which is difficult to classify and control. At the same time, some drainage facilities have been constructed for a long time, and the problems such as aging and structural defects are prominent. The control system and mechanism of drainage source facilities need to be improved. The regional drainage household management mechanism, supervision mechanisms and existing problems in Shanghai are deeply studied. The measures such as intelligent overall planning, hierarchical control, local conditions and classified supervision are proposed in order to provide the reference for the fine management of drainage households in the megacities.
