Promoting the scale integration of rural water supply and optimizing the urban-rural water supply pattern are fundamental measures to improve the guarantee capacity of rural water supply and achieve high-quality development of rural water supply. The northeastern part of Guangdong Province is a mountainous area

and its rural water supply faces challenges such as scattered and uneven water sources

incomplete supporting facilities

and difficult and sustainable operation and maintenance. This article takes Wuhua County in Guangdong Province as a case study to conduct research. In response to the above challenges and following the development concept of large-scale integrated water supply

Wuhua County has gradually established a rural water supply development pattern of “scale development

standardized construction

integrated management

specialized operation

and intelligent service” by optimizing water source allocation

forming a networked water supply pattern

carrying out standardized construction

realizing county-level unified management and specialized management

and building an intelligent service system. This has effectively promoted the high-quality development of rural water supply. This development practice case can provide references for rural water supply work in similar regions.
