A rainwater collection and utilization system for municipal engineering

technical field

The utility model relates to the technical field of municipal construction and construction, in particular to a rainwater collection and utilization system for municipal engineering.

Background technique

With the acceleration of urbanization, some cities in our country have serious problems such as shortage of water resources, pollution of water environment, flood disasters and deterioration of ecological environment. As a key element in the water circulation system, rainwater plays an important role in the construction of a sustainable urban water circulation system. Therefore, how to effectively collect and utilize urban rainwater has become an important issue that must be paid attention to in the environment, municipal administration, planning, architecture, landscape, water conservancy and so on.

At present, urban rainwater is mainly discharged into the urban groundwater pipe network through the drainage ditches on both sides of the road, and finally converges into the rivers, seas and lakes. However, because urban rainwater usually entrains some urban garbage and pollutants, it is directly discharged into rivers, seas and lakes, causing pollution pressure to the water environment; on the other hand, the direct confluence of urban rainwater to rivers, seas and lakes plays a very limited role, and rainwater has not been effectively used. .
