To promote the effective development of the South-to-North Water Diversion Project, taking the water receiving area in Jiangsu as the research object, the current water-saving measures and effects are analyzed, and the research methods for water-saving potential are determined from three aspects of life, agriculture and industry. Based on the achievable water-saving target, the water-saving potential is calculated. According to the principle of “water-saving first and then water transfer”, the dispatching scale of the eastern route project of the South-to-North Water Diversion Project in Jiangsu is determined, and the economic, social and ecological benefits of water-saving are analyzed. The research shows that the water-saving potential of the water receiving area in Jiangsu is 1.59 billion m3 in 2030, and the main water-saving potential is in agriculture. Compared with the conventional scheme, the total pumping volume can be reduced by 2.83 billion m3 under the optimal water-saving scheduling scheme, which can reduce the energy consumption of the pumping station by 54.28 million kW·h, and the water-saving economic benefit reaches 2.76 billion yuan. The research results provide ideas for further optimizing the allocation of water resources in the water receiving areas of Jiangsu in the eastern route of the South-to-North Water Diversion Project and implementing the policy of water control in the new era.
