Abstract:This paper sorts out the construction foundation and advantages of the provincial pilot project for reclaimed water utilization and allocation in Guanxian County, analyzes the current status and core problems of reclaimed water application, systematically summarizes implementation paths including optimized allocation, enhanced management and improved facilities, and calculates its comprehensive benefits. The study shows that by establishing a circular system of "sewage-treatment-reclamation-utilization", improving policy mechanisms and expanding utilization scale, Guanxian County can achieve a reclaimed water utilization rate of over 55% by 2027. Its model featuring "linkage of wastewater plants and pipe networks, graded water supply and demonstration-driven development" can provide references for the resource utilization of reclaimed water in similar regions.
