Rural water supply security is not only an important task tocomprehensively promote rural revitalization, but also a concretemeasure to realize integrated urban-rural development and theequalization of urban and rural basic public services. YunnanProvince is located in the southwest of China, with mountainousand semi-mountainous area accounting for 94% of theprovince's total area.Due to a large rural population, YunnanProvince rural water supply security task is heavy. After years ofconstruction, all drinking water safety problems for people livingout of poverty under the current standards have been solved, butproblems still exist, such as the security level of the quantity andquality of water supply sources in rural areas is not high, andthere is a big difference between urban and rural water supplyoperation and management.

From 2022 to 2024, 407 integrated urban andrural water supply projects will be implemented to improve watersupply security for 17.84 million urban and rural water users, andthe proportion of the population served by integrated urban andrural water supply will increase from 43.9% to 87.1%. Based onthe analysis of the characteristics of urban and rural watersupply in Yunnan province, this paper introduces the mainpractices and experience results of the integration of urban andrural water supply in Yunnan Province, discusses the problemsencountered in the implementation process, and puts forwardcountermeasures and suggestions from the aspects of projectplanning and construction, operation and management,investment and financing mode, water price reform and so on.
