During the construction process of most cities in our country, they often only pay attention to geographical expansion. Concrete and asphalt pavements are common, and the problem of ground hardening is very serious. The planning of underground drainage facilities and above-ground flood control capacity is not in place, and the investment is obviously insufficient. Most of the existing urban flood control standards are at the level of a 5-year flood, and there are very few cities that can withstand a 10-20-year flood. With the rise of real estate, land resources are becoming more and more precious, and the original small lakes, ponds, creeks, ditches and other places that can stagnate and store water are becoming less and less. All the rainwater is quickly discharged into the river, and the water level soars. Under the support of the water level, it cannot be discharged, so that a heavy rain, sometimes an ordinary precipitation, can also cause a large loss of flood disasters.

Precipitation in most parts of my country is concentrated in summer and autumn, and less in winter and spring. Due to historical reasons, there are very few cities in our country that have realized the separation of rainwater and sewage. Although some cities or new cities are now engaged in sewage interception to promote the concept of environmental protection to the common people, the problem of throwing garbage and sewage into urban rivers is still a problem. very grim. In the absence of replacement and circulation of running water, the water in urban rivers deteriorates, turning black and smelly, which seriously affects the daily life and public health of residents, and also affects the normal development of water entertainment activities, and more seriously affects the urban environment. Image and normal functioning of socio-economic activities.

Under the normal combination of water levels, the probability of artesian drainage and introduction of running water in urban rivers along riverside and lakeside areas is low during the flood season and winter season. Therefore, it is the current practice to build pumping stations for drainage and introduction of running water. The problem we are facing is how to give full play to the role of existing water conservancy facilities, reduce project construction land, reduce project construction investment, and maximize economic, engineering and social benefits.
