- Abstract:
- Based on a provincial investigation of rural domestic sewage treatment facilities conducted in 2021, along with research on maintenance systems, funding, and modes over the past three years, this paper summarizes the construction and maintenance status of rural domestic sewage treatment facilities in Guangdong Province. Key factors affecting sustainable maintenance were identified through a life cycle analysis, indicating that the establishment of sustainable maintenance should consider at least five aspects: planning, design, construction, maintenance and post-maintenance. Additionally, combined with the current maintenance management improvement measures in Guangdong Province, the paper proposes that a well-developed mechanism is the key to realize sustainable maintenance management, including clear division of responsibilities, good maintenance management system, sufficient financial guarantee and effective supervision and assessment. The optimization paths for the three governance models are also deeply discussed from the perspective of supply and demand. To build a stable maintenance management system, the supply and demand among the government, enterprises and farmers should be well balanced, and the multi-center governance and diversified participation are also strengthened. It is indicated that the collaborative maintenance model is an effective measure to reduce maintenance costs and ensure quality.
