“引大济岷”工程启动建设！大渡河将“携手”岷江润泽“天府之国”

Core Viewpoint - The "Yin Da Ji Min" project, the largest water diversion project in Sichuan's history, has officially commenced construction to address the water scarcity issue in the Chengdu Plain by connecting the Dadu River and the Min River, creating a dual water source [1][2]. Group 1: Project Overview - The project has a total construction period of 8 years, with the water intake point located 3.5 kilometers upstream of the Luding Hydropower Station on the Dadu River [1]. - It consists of a main line and two branch lines, extending over 260 kilometers through tunnels and pipelines to deliver water to two junction points located over 100 kilometers and 40 kilometers from the Dujiangyan water conservancy hub [1]. - By 2040, the project is expected to divert 1.389 billion cubic meters of water to the Chengdu Plain, increasing to 1.523 billion cubic meters by 2050 [1]. Group 2: Impact on Water Supply - The project aims to primarily support urban and industrial water supply while also considering agricultural irrigation, potentially benefiting 34.13 million people across 43 counties in the Chengdu Plain economic zone [1]. - The water supply guarantee rate for urban and industrial use is projected to increase from 90% to 97%, while the agricultural irrigation guarantee rate is expected to reach 80% [2]. - The project will enhance the spatial and temporal distribution of water resources in Sichuan, ensuring water security for the Chengdu Plain economic area and supporting high-quality economic and social development in the province [2].
