Have you ever thought that the rain in the sky can also be sold for money?
Recently, China’s first “rainwater transaction” was successfully concluded in Changsha. Hunan High-tech Property Co., Ltd. sold its collected rainwater resources at a price of 0.7 yuan per cubic meter.
On December 16, in Changsha High-tech Zone, Hunan Province, a sanitation sprinkler drove slowly to the street after loading water, and began to wash the leaves of green trees on the roadside. This marked the first rainwater resource use right transaction in China After the success, the first rainwater was officially put into use.
Zeng Fuan, the person in charge of Hunan Yuchuang Environmental Protection Engineering Co., Ltd.: After collecting it through our community’s pipe network, it is processed and then reused to meet the national miscellaneous water quality standards.
The treated rainwater is purchased by the local greening and sanitation department at a price of 20% lower than that of tap water for use in landscaping and sanitation cleaning water. This approach not only reduces the daily cost of the greening and sanitation department, but also reduces the demand for high-quality urban tap water.
In 2018, Changsha began to promote the construction of a “sponge city”, always hoping to absorb and save rainwater, and use it when needed. The water rights transaction reached this time marks the capitalization of rainwater resources, which also provides new ideas for the nationwide development of “sponge cities” and the rational development of natural resources.
Liu Bo, Secretary-General of Changsha Sponge City Ecological Industry Technology Alliance: We have been promoting rainwater collection and utilization. There are 27 sponge city rainwater storage modules in Changsha High-tech Zone alone, and there are more than 500 in the city.
At present, 70,000 cubic meters of rainwater collection ponds have been built in Changsha City. After the processing of rainwater resources and the trading of the right to use them, it is estimated that 700,000 cubic meters of tap water can be saved each year.
