Abstract:This paper analyzes the construction of the modern water grid in Junan County and points out existing problems. It puts forward important measures such as strengthening the construction of the water grid under the overall planning of water resources, water ecology, water safety and water culture, promoting the construction of digital twin water grid, and adhering to the integrated urban-rural water grid construction. The measures continuously improve "the main framework" and smooth "the microcirculation", comprehensively advance the construction of the modern water grid, and provide replicable demonstration experience for the construction of county-level water grid across the country.
