At present, my country is a country with a low per capita water resource in the world, and the water resource of tap water in our country is scarce. In recent years, due to the long-term housing optimization in our country, there are many high-rise buildings everywhere, which are used for green irrigation, construction, industry, A large amount of tap water is used for fire fighting and car washing. During the rainy season, the rainwater in the community is generally discharged into the municipal sewer network through the ground, but when the amount of rainwater is large, the municipal sewer network cannot meet the discharge of a large amount of rainwater, which will easily cause water accumulation on the roads of the community and make it difficult for people to travel , especially in the rainy season when there is a sudden rainstorm, most of the residential areas do not have rainwater collection and storage facilities, because the rainwater cannot be discharged in time, and even the rainwater causes the underground garage to be flooded. A large amount of rainwater, during the rainy season, the phenomenon of rainwater accumulation in the community occurs from time to time. In view of the above reasons, a centralized collection and purification system for rainwater drainage in the building community is proposed.

Utility model content

The purpose of this utility model is to overcome the lack of water resources of tap water in our country.
