China Buried a $60 Billion River Underground — But Why?

China’s $60 Billion South-to-North Water Diversion Project: How China Built an Underground River to Save Beijing from Water Crisis China dug a $60 billion underground river to save Beijing — moving water more than 1,200 km from the Yangtze River system to the capital. This is the full story of the world’s largest water transfer project, the South-to-North Water Diversion Project (also called the South-North Water Transfer Project). Beijing faced a severe water shortage and groundwater crisis for decades. Water tables dropped, land subsided, and the city of over 20 million people was running out of water. China’s solution was one of the greatest engineering megaprojects in history: diverting massive amounts of water from the wet south to the dry north through canals, tunnels, aqueducts, and buried pipelines. In this documentary you’ll discover: • Why Beijing’s water crisis forced China to build the South-to-North Water Diversion Project • How the Middle Route moves water 1,200–1,400 km mostly by gravity from the Danjiangkou Reservoir • The massive tunnels built under the Yellow River so water from the Yangtze basin can pass beneath another major river • Why more than 300,000 people were relocated when the Danjiangkou Reservoir was expanded • How the project contains over 1,700 major structures — aqueducts, inverted siphons, tunnels, bridges, and control gates • Why the water disappears underground as it approaches Beijing through enormous buried pipelines • How the diversion is reducing Beijing’s dependence on groundwater and helping fight land subsidence • The environmental questions and hidden costs of moving water across China This is the complete story of China’s South-to-North Water Diversion Project — the engineering, the human cost, the environmental trade-offs, and the bigger question of who controls water when a country can move it wherever it wants.
