The main feature of this technology is the use of rainwater to cool the urban environment, writes Slashgear. During periods of extreme heat, the tanks are supplied with a special spray system that irrigates roads and sidewalks. As the water evaporates, it draws heat from the concrete and asphalt, lowering the air temperature on the streets. This not only makes being outdoors more comfortable, but also helps reduce the urban heat island effect faced by megacities around the world.
In addition to cooling, the stored water is actively used for landscaping and maintenance of urban spaces. Parks and squares are watered exclusively with rainwater, and streets and sidewalks are washed without using precious supplies of potable water. This approach saves significant resources by reducing the burden on the water supply and the energy required to transport and treat the water.
Experts note that this project is an example of an integrated approach to urban water management. The system both prevents floods by accumulating excess precipitation and creates comfortable climatic conditions for residents. It demonstrates how competent use of natural resources can change the image of a modern city, making it more sustainable and environmentally friendly.
The South Korean experience shows that innovation in infrastructure can be not only technically sophisticated but also environmentally significant, improving the quality of life and creating a model for other megacities around the world. This approach transforms rain from a potential threat to an invaluable resource, ensuring harmony between nature and urbanism.
