US Army Is Building a 42 Million Square Meter Reservoir Worth $4 Billion to Save the Everglade

The U.S. Army Is Building a 42-Million-Square-Meter Reservoir Worth $4 Billion to Save the Everglades For more than a century, South Florida’s natural water system has been heavily altered by canals, levees, and flood-control infrastructure. Water that once flowed slowly through the Everglades is now often diverted directly to the coast, contributing to environmental degradation, harmful algal blooms, and increasing pressure on freshwater supplies. To address this problem, the U.S. Army Corps of Engineers is helping construct the Everglades Agricultural Area Reservoir, a massive project designed to restore part of the region’s lost water cycle. Covering more than 42 million square meters and capable of storing up to 78 billion gallons of freshwater, the reservoir will become one of the largest above-ground water storage facilities ever built in the United States. Building it requires enormous engineering efforts, including a 27.8-kilometer underground seepage barrier, giant levees, pumping stations, canals, and one of the world's largest constructed wetland treatment systems. In this documentary, Mandarin Tech explores how engineers are transforming former sugarcane farmland into a critical piece of water infrastructure. Discover the technology, challenges, and environmental goals behind a four-billion-dollar megaproject that could help restore the Everglades, improve water quality, and protect freshwater supplies for millions of people across South Florida. Follow Mandarin Tech as we reveal how engineers built a masterpiece deep underground — and shocked the world.
