Infiltration wells act as “underground reservoirs” and “purifiers” for rainwater. Instead of directly discharging rainwater into the pipe network, they use a filtration layer within the well to trap impurities and then guide the rainwater to slowly infiltrate into the ground, replenishing the city’s dwindling groundwater. In sponge city construction, they function as an “invisible sponge,” transforming rainwater from “rapid drainage” to “recycling,” alleviating drainage pressure, improving the urban hydrological environment, keeping the soil moist, and providing natural nourishment for vegetation growth.

Overflow wells act as “emergency safety valves” for urban drainage. When the intensity of heavy rainfall exceeds the capacity of the pipe network, or when the infiltration wells are full and can no longer absorb rainwater, the overflow wells will activate “diversion mode.” This diverts excess rainwater through pre-set overflow channels into natural water bodies such as rivers and lakes, preventing rainwater from flowing back into residential areas, basements, or main roads. This minimizes losses caused by urban flooding and builds a “last line of defense” for the safety of citizens’ travel and property.
