Group 2: Impact on Water Supply - The project will serve 43 counties in 8 cities, including Chengdu, Deyang, and Mianyang, potentially benefiting 34.13 million people and increasing irrigation area by 1.79 million acres while improving 5.91 million acres [3]. - The water supply guarantee rate for urban and industrial use in the Chengdu Plain will rise from 90% to 97%, while agricultural irrigation guarantee rates will reach 80% [3]. Group 3: Historical Context - The concept for the "Yin Da Ji Min" project was proposed as early as the 1950s and has undergone decades of investigation and validation before receiving national approval for construction [3].

Core Viewpoint - The "Yin Da Ji Min" project has been officially launched to address the water scarcity issues in the Chengdu Plain Economic Zone by diverting water from the Dadu River, enhancing the water supply for agriculture and industry in the region [3][4]. Group 1: Project Overview - The "Yin Da Ji Min" project will take 8 years to complete and will utilize natural elevation to transport water through over 260 kilometers of tunnels and pipelines [3]. - By 2040, the project is expected to divert 1.389 billion cubic meters of water to the Dujiangyan irrigation area, increasing to 1.523 billion cubic meters by 2050 [4]. Group 2: Regional Water Challenges - Sichuan Province, known for its abundant water resources, faces significant spatial and temporal distribution challenges, with a "west-rich, east-poor" water resource situation [3]. - The population in the Chengdu Plain Economic Zone is projected to exceed 46 million by 2030, leading to a more severe water supply gap by 2035 [3]. Group 3: Benefits of the Project - The project will improve the water supply guarantee rate for urban and industrial use from 90% to 97%, and for agricultural irrigation to 80% [4]. - It will serve multiple functions including urban water supply, irrigation, ecological replenishment, and emergency water sources, benefiting 34.13 million people across 43 counties [4].
