However, most of the existing rainwater storage systems are used for building a sunken green land in urban greening, wherein the ground is higher than the green land, and rainwater retention facilities are designed in the green land. The urban green land and the lawn can absorb rainwater more through the planning and construction of urban greening such as public green land, unit affiliated green land, residential green land, protection green land, finished green land, windfarm green land, road green land and the like in urban planning. However, all of these plans are solutions for urban rainwater storage, which results in rainwater being discharged again after rainwater is stored, and the value that rainwater can be reused is not reflected. Along with the development of cities, water resources on the earth are in shortage, water conservation is not slow, rain sewage in urban green areas is effectively utilized, and the method is an effective way for solving the water resource shortage. However, there is currently no reasonable urban planning of a complete system for the utilization of rain sewage. When a large amount of rainfall is carried out, drainage is carried out by adopting modes such as a pump and the like, or the traditional mode causes that drainage cannot be carried out in time, and waste is caused to water resources. In order to save water resources, the water resources are fully utilized, and rainwater is collected, treated and reused to form a sustainable road.
