Low impact precipitation disposal system

The utility model discloses a low-influence rainfall disposal system, which comprises a sponge body pavement surface, a rainwater storage tank, a rainwater storage tank, a rainwater storage tank and arainwater purification tank, the rainfall storage and seepage buffer pit is used for collecting, storing, seeping, precipitating and dredging rainfall and transferring buffer water into an urban drainage pipe network; and the precipitation and seepage collection closed conduit is used for organizing and guiding water in the sponge body pavement surface to the precipitation and seepage storage buffer pit and enabling seepage water to enter a soil layer. The system has the effects of absorbing, collecting, storing, infiltrating and slowly releasing rainfall, so that urban inland inundation is relieved, urban runoff pollution load is reduced, rainfall resources are protected, and a technical scheme is provided for constructing sponge cities. 本实用新型公开了一种低影响降水处置系统，包括：海绵体铺装面，用于促进雨水的积存、渗透和净化；降水蓄渗缓冲窖，用于对降水进行集水、蓄水、渗水、沉淀、清淤
