The figures were amazing as they continued estimating that Chinese people wash hands on average five times every day. 

“If we say that every Chinese person uses 600 ml of water every time, our country uses an annual of 1.75 billion tons [of water] only for hand-washing, it’s about the water storage of 121 West Lakes,” Zheng said. 

“But if we save 90 percent of the water, we can use it to generate 670 gigawatt hours of power, irrigate one million hectares of farmland, or meet the basic water needs of people living in West China for one year,” Zheng added. 

He saw the great potential to save water, as well as the great business opportunities lying behind his idea. 

Practice makes perfect. Now with a concentrated water atomizing system and an air compression set, both winning China’s patent recognition, Zheng’s automatic faucet can give users an easy and enjoyable feeling of hand-washing. 

“This is only a sample model, we will continue to upgrade our product and develop it with more and more friendly features,” Zheng said. 

Investors from Tsinghua University, Zhejiang University, the Yinchuan municipal government, the United Nations Development Programme, and China Capital Museum have expressed their interest to Zheng. 

“We are now focused on serving establishments with large flows of people, such as shopping malls, railway stations, airports, highway service areas, and tourist spots. We will price at about 1,000 yuan per faucet and the market assessment is about 10 billion yuan,” Zheng said.
