- Abstract:
- Urban combined sewer system retrofit and overflow control involve a series of long-term and major impacts on urban development. So a careful determination should be made through scientific and systematic analysis and assessment from the whole prospect. The bottleneck issues in terms of laws, regulations and control mechanism, policy requirements, standard and technical guide, relevant special planning were analyzed, and the key improvement focus were put forward. The typical strategy selection and classification of typical cities in China were analyzed. Then, the key elements of scientific determination for urban “combined sewer separation” and CSO control strategies were put forward, which included clear clarification of the current situation, key issues and major limiting factors of urban combined sewer and relevant drainage system, setting reasonable targets of pollution load reduction of drainage system, assessment of strategy implementability, effects and cost, optimization of technical strategy, establishment of implementation guarantee and adjustment mechanism.
