The technology allows rainwater to flow into a water tank and lets it evaporate and radiate heat during warmer weather. This prevent floods and improves the urban heat island effect.

Chen Shen-xian, deputy mayor of Xinbei City and president of the Taiwan Association of sustainable Ecological Engineering Development, understands and appreciates JW Eco-Technology. But the technology clashes with traditional road construction methods and upstream and downstream industries, so it needs to be implemented with caution.

Citizen journalist Xie Ming-hai points out that the public parking lot at the end of Shipai Rd. in Taipei City is already paved with JW Eco-Technology and more parking lots might follow in its steps. Foundations need to be over one meter deep in order to apply the technology and the process is very complicated.

The Taiwanese inventor of JW Eco-Technology, Chen Jui-wen, only holds a junior high school diploma, but is a talented creator.

Radio Taiwan International reports, Chen Jui-wen moved to Taipei to work after graduating from junior high because of his poor academic performance. His job was related to road construction and he started to look for ways to drain rainwater from cities and countrysides.

Chen realized that if the ground can absorb water, in addition to water conservation, it can also reduce urban heat island effect, so he began to develop JW Eco-Technology. In the meantime, he sold his house and property, and insisted on finding the best way to pave roads. Though Chen’s family didn’t understand his insistence and he failed countless times, he finally succeeded.

China Times reports, Chen says the loading capacity of the roads constructed with JW Eco-Technology is much larger than the current permeable pavement for passengers, park or small vehicles. Therefore, the U.S., China and other countries have approached Chen for this patent and invite him to collaborate with local engineering teams to build this “breathing road," also known as a sponge road.

In order to widely promote this invention in his own country, Chen never charged any public or private institution a penny for using JW Eco-Technology, including the Xi-zhe Community. He even took initiative to send official notifications to the Xinbei City and Taipei City government to give up all rights of this patent if any public construction institution would like to implement JW Eco-Technology and benefit the environment.

According to the Sustainable Public Infrastructure, Jungong Car Park built by the Taipei City Parking Management and Department Office is the first permeably paved parking lot. The technology allows rainwater to flow into a water tank and lets it evaporate and radiate heat during warmer weather. This prevent floods and improves the urban heat island effect.

The workers first pave a layer of sand and gravel at the bottom, place on the water pipe and top it with cement. The last step is to leave the water delivery pipe on the ground to recycle ground water for other uses. When the water evaporates, it can take away heat and cool down cities, just like a breathing parking lot.
