Water supply throughout China has been depleting, and the management of these dwindling resources has posed new and urgent challenges. To address these issues, different water supply strategies have been developed and evolved. As a result, water conservation and management practices must evolve correspondingly. On the other hand, as water resource demands continue to grow, local utilities need to adopt and implement innovative measurement solutions as part of their water management practices(1,2). As an effort to bridge the gap, this research focuses on building a Smart Water-Supply System that can become an integral part of the city management and the building block of low-carbon residential environment to construct the Smart City at Guangzhou, China. Both the internal management and citizens service requirements are combined into the construction of the system(3,4). The designed system has the characteristics of details perception, economy and efficiency, self-healing control and interactive service. The demonstration of this smart system has achieved very good results by promoting users service level, improving the management of water supply operation, as well as reducing the energy consumption. The significant benefits that can be brought by the proposed system include: transparent water consumption to Water-Supply companies and end users, promotion of scientific and economic water consumption, large economic benefits to Water-Supply Companies, and assistant decision-making for social management.
