The aim of this study is to scientifically implement water diversion projects and effectively provide water security for high-quality development and environmental protection. The research progress of water diversion projects is reviewed in terms of industry standards, specifications, and related studies. It was found that water demand prediction tends to be overly high, the integrity of comprehensive benefit evaluation needs to be improved, the standard of ecological compensation mechanism remains incomplete, and post-evaluation and tracking work is insufficient. To support the spatial equilibrium of water resource allocation and the construction of national water networks, future water diversion projects need to strengthen environmental protection and whole-stage follow-up evaluation, perform full cost pricing, perfect the investment and financing system, and improve information and intelligent management.
