Chengde Longzhida———Smart water meters are crucial for rural drinking water upgrades.
Release time:2021-07-12
Water is the source of life, yet in rural areas, due to geographical and other factors, access to water has long been unreliable. Since the founding of New China up until 2015, China’s rural water supply system has gone through four distinct stages: natural development, the initial stage of providing drinking water, alleviating drinking-water difficulties, and ensuring drinking-water safety. Since the implementation of the Rural Drinking-Water Safety Project, a total of 520 million rural residents and over 47 million teachers and students in rural schools have had their drinking-water safety issues resolved. However, the challenges remain severe, and continued efforts are still needed.
