- Abstract:
- Urban drainage network is an important aspect of urban water related projects. With the expansion of the city, the problems of underground drainage network are gradually exposed and become increasingly serious. In order to speed up to improve urban sewage collection system and treatment facilities, governments have issued relevant documents to improve the quality and efficiency of the drainage system. The local authorities are required to carry out repairing and transformation of the pipe network, which could lay the foundation for realizing the goal of full coverage, full collection and full treatment of the sewage pipe network as soon as possible. Considering that the work will face different difficulties, and the specific regional characteristics are also different, one-size-fits-all kind of the pipeline detection, repair, and transformation not only cost incredible funds and labor work, and the consequences may not be satisfactory. Thus, it is very essential to reasonably and scientifically arrange the short-term and long-term actions, and guide the local authorities to formulate action plan from the perspective of top-level design with systematic thinking and professional guidance. Based on the preliminary work, we put forward the idea of preparing the sewage pipe network action plan based on the “zoning and governance” policy, which provides a compilation program and analysis method for the preparation of the action plans for similar drainage pipe networks. Combined with the practice in Jiangbei District of Ningbo City, a comprehensive evaluation method of sewage pipe network system based on the analysis using Geographic Information System is constructed, which provides a strong support for a scientific and reasonable arrangement of reconstruction projects.
