Low Impact Development for Urban Rainwater Collection and Utilization: In many large cities in China, heavy rain often leads to street flooding and traffic congestion. Rainwater, which should be a resource, has become a problem for Chinese cities.

The reason lies in the rapid urban development and the increasing proportion of impermeable surfaces. How cities can eliminate flooding, conserve water resources, and achieve rainwater collection and utilization has become one of the major challenges in urban development.

Importance of Rainwater Collection
1. China is listed by the United Nations as one of the 13 water-poor countries in the world. The per capita available freshwater resources are low, only a quarter of the world average.
2. Continuous over-extraction of groundwater has led to a decline in groundwater levels, loss of rainwater resources, and the formation of groundwater funnels.
3. Rapid urbanization has increased the proportion of impermeable surfaces, shortening rainwater convergence time, increasing peak flow, and causing frequent waterlogging disasters.

Meaning of Rainwater Collection
Rainwater collection and utilization refer to the measures taken to collect, infiltrate, store, treat, and use rainwater locally due to increased runoff caused by building roofs and hardened surfaces. These include:
1. Direct use after collection, storage, and purification;
2. Infiltration of rainwater into the ground through various artificial or natural infiltration facilities to replenish groundwater;
3. Utilization of various artificial or natural water bodies, ponds, wetlands, or low-lying areas to regulate, purify, and utilize rainwater runoff, improving the urban water environment and ecological environment.
