The Ms6.2 magnitude earthquake that struck Jishishan County, Gansu Province, on December 18, 2023, caused varying levels of damage to different engineering structures in the region, resulting in significant casualties. In order to study the impact on the water supply system, based on the investigation data, the seismic damage characteristics of buildings, structures, facilities, equipments, and water supply pipeline networks were summarized. The study revealed that structures designed and constructed to be earthquake-resistant experienced relatively minor damage, highlighting the effectiveness of China’s earthquake-resistant design standards. The water plant located in the low-intensity zone was shut down as a result of the earthquake, with oil leakage from certain equipment leading to water contamination and a reduction in water supply capacity. Additionally, the water supply pipeline network in the high-intensity zone sustained multiple damages at the connections of the old steel pipelines, resulting in water shortage and reduced water pressure that adversely impacted residents’ lives. Finally, four recommendations for recovery and rebuilding were proposed, including the adoption of seismic isolation techniques for equipments, the use of flexible connections for pipe-equipment interfaces, the selection of water supply pipe materials, and the conduct of a comprehensive leakage survey of the pipe network.
