Roof Rainwater: Roof rainwater is relatively clean with minimal impurities, silt, and other pollutants. It can be directly discharged into the water storage system after overflow and simple filtration for treatment and use.

Surface Rainwater: Surface rainwater contains a high amount of impurities and has complex sources of pollutants. After runoff and coarse filtration, sedimentation is still necessary before it can be discharged into the water storage system.

System Features

1.Through various system processes and filtering, the initial rainwater undergoes multiple pre-treatment stages, ensuring the collected rainwater quality.

2.Utilizing water storage modules for water retention ensures high water quality without taking up space, with simple construction, enhanced environmental friendliness, and safety.

3.Easily direct rainwater to water points using pressure control pumps and rainwater controllers, while the controllers provide real-time updates on the water level in the storage tanks.

System Processes 

The Rainwater Collection and Utilization System is designed to collect, store, and utilize precipitation. Mature rainwater utilization technology involves the following steps: water collection → pollution interception → filtration → storage./Integrated standardized products and assembled complete sets for infiltration, enhancement, reuse, and control. 

System Application

1.Rainwater Harvesting System

Rainwater harvesting involves collecting roof, pavement, and green area rainwater into rainwater wells, where it is then collected and overflowed through分流 systems. The collected rainwater is initially treated through stormwater interceptors, flow-through, and filtration before being stored in a reservoir. After natural sedimentation in the reservoir, the water is further disinfected and can be used for various purposes, including landscaping, flushing toilets, road washing, vehicle washing, and replenishing scenic water bodies.

2.Rainwater Percolation System

Rainwater infiltration replenishes groundwater resources, improves the ecological environment, and supplements freshwater through reservoirs. Common methods of rainwater infiltration include: depression green space infiltration, natural depression infiltration, permeable well water infiltration, and infiltration pond infiltration.

3.Rainwater Harvesting System

The rainwater retention system temporarily stores rainwater in a retention pond during heavy rain seasons. After the heavy rain subsides, the water from the retention pond is pumped into the stormwater drainage network. This rainwater retention system effectively reduces the peak runoff volume in the municipal stormwater管网 during heavy rains, playing a significant role in flood prevention and waterlogging control, as well as in the construction of sponge cities.
