城市人口密度大,再加上城市运行和发展也需要水资源,因此城市对水资源的消耗非常大,所以必须要做好给排水工作。城市如果出现了水资源紧缺,不仅会影响居民的生活,还会影响城市的正常运转;另外,城市的排水系统如果比较差,在强雨雪天气,城市中积水无法及时排出,必然会造成内涝问题,给城市的发展和运行带来困难。现阶段提倡建设环保型社会和资源节约型社会,所以在城市用水、污水排放、污水治理、水资源的回收利用等方面都需要严格按照可持续发展理念为基础,完成市政给排水的设计。
The density of urban population, coupled with the city’s operation and development also need water resources, so the city’s consumption of water resources is very large, so we must do a good job of water supply and drainage. If there is a shortage of water resources in the city, it will not only affect the lives of residents, but also affect the normal operation of the city. In addition, if the city’s drainage system is relatively poor, in strong rain and snow conditions, water in cities cannot be discharged in time, which will inevitably result in Intrinsic problems have brought difficulties to the development and operation of the city. At this stage, the construction of an environment-friendly society and a resource-saving society is advocated. Therefore, in the urban water, sewage discharge, sewage treatment, and recycling of water resources, the design of municipal water supply and drainage must be completed in strict accordance with the concept of sustainable development.
