From the point of view of this case, the rain sewage diversion construction ignored the potential problems of the old neighborhood pipeline, in the beginning of the project design did not take it into account, and the old neighborhood's own pipeline due to the lack of property, the essence of the state of lost control, the two together, resulting in the later that the rain sewage diversion system appeared to be poorly functioning, the residents of the home backed up water, resulting in damage to property.
The rainwater and sewage diversion project itself is a project for the people, but in the process of docking, especially in the old city, it is necessary to take into account the old equipment and pipelines, its carrying capacity, its life, its maintenance, whether it needs to be replaced and so on a series of argumentation.
Since rainwater is lightly polluted, after diversion, it can be discharged directly into the city's inner rivers, and after natural precipitation, it can be used as natural landscape water, or as urban municipal water supplied for spraying the roads, so the rainwater can be purified and buffered to flow into the rivers, which can improve the efficiency of the use of surface water. At the same time, let the sewage discharged into the sewage network, and through the sewage treatment plant treatment, sewage regeneration and reuse.
Rainwater and sewage diversion can speed up the sewage collection rate, improve the sewage treatment rate, avoid sewage pollution of rivers and groundwater, significantly improve the urban water environment, but also reduce the cost of sewage treatment, which is a major benefit of rainwater and sewage diversion.
Rain sewage diversion facilitates the collection and utilization of rainwater and centralized management of discharges, reduces the impact of water volume on the sewage treatment plant, and ensures the treatment efficiency of the sewage treatment plant. Will greatly enhance the city's environmental quality, urban taste and management level, and effectively improve the living environment and quality of life of the general public.
