Core Viewpoint - The Ministry of Water Resources has issued guidelines to prioritize water conservation in water diversion projects, aiming for sustainable development in water-receiving areas through systematic and long-term water-saving efforts [1][2]. Group 1: Water Conservation Strategy - The guidelines emphasize a dual approach of both water diversion and conservation, with a focus on enhancing water use efficiency and effectiveness in water-receiving areas [1]. - By 2030, the management of water-saving evaluations is expected to be improved, with water consumption per ten thousand yuan of GDP and industrial added value, as well as effective irrigation water utilization in agriculture, surpassing the national average [1]. - By 2035, the total water resource management and comprehensive conservation systems in water-receiving areas are to be further refined, achieving advanced levels of water resource conservation and utilization efficiency [1]. Group 2: Implementation Measures - During the planning phase of major water diversion projects, strict adherence to water-saving evaluation systems is required to scientifically determine project scale and layout [1]. - The guidelines call for the integration of water-saving facility construction during the project development phase and the strengthening of supervision over the execution of water-saving evaluations [1]. - Post-implementation, regular assessments of the effectiveness of water-saving measures in water-receiving areas will be conducted [1]. Group 3: Deep Water Control Strategy - The guidelines stress the implementation of a deep water control strategy, mandating the comprehensive application of the "Four Waters" principle, which includes determining urban planning, land use, population distribution, and production based on water availability [2]. - Key water-saving indicators are to be enforced with rigid constraints, optimizing multi-source water allocation and exploring water budgeting management [2]. - The establishment of a long-term mechanism for prioritizing water conservation in water-receiving areas is to be accelerated through detailed implementation of water-saving policies [2].
