Abstract: Aggregate full-cycle water conservation data from 47 500-kV transmission and sub-station projects in the Jiangsu Plain Water Network Area from 2015 to 2024. Project characteristics, including project scale and disturbed soil-and-rock area, were extracted to construct a database for statistical analysis. The results show that drilled piles accounted for 87.75% of foundations, while mud generated during single-foundation excavation accounted for 53.96% of the total excavation material. Disposal was predominantly conducted through in-situ landfill (98.93%). Based on these findings, it is recommended that landfill disposal be restricted; measures for dewatering, volume reduction, and harmless treatment be implemented; resource utilisation be promoted; and whole-process supervision with clear responsibility mechanisms be established.

Keywords: Jiangsu Province; plain water network area; power transmission project; water and soil loss; prevention and control measures.
