How Indonesia is Building the Impossible $80B Giant Sea Wall

Jakarta Giant Sea Wall construction: How Indonesia is building an $80 billion coastal barrier to save 55 million people. Jakarta is sinking 17 centimetres a year. 40% of the city already sits below sea level. Indonesia's answer: an $80 billion sea wall — 32 kilometres of offshore concrete construction sealing Jakarta Bay, eight giant pump stations built into the wall to lift 13 rivers over it, and a freshwater lagoon engineered where the open ocean used to be. Then the Pantura plan: 575 kilometres of coastal engineering running the entire Java north coast, protecting 55 million people — the largest sea wall construction project in human history. This engineering documentary covers the full construction breakdown from zero: • Marine surveys on liquid mud and seabed stabilization • 5,000-tonne caissons fabricated on land, floated 8 km, and sunk onto sand foundations • 8 massive pump stations moving 100 cubic metres of river water per second • The sealed lagoon freshening from saltwater to freshwater as 13 rivers replace the tide • 575 km of sea wall construction planned across five provinces of Java's north coast 🔔 Subscribe to NextGen Manufacturing for in-depth engineering breakdowns, mega machines, and the blueprints shaping our future! #GiantSeaWall #Megaprojects #Engineering #Construction #Indonesia #Jakarta #CoastalEngineering #Infrastructure ⏱️ Timestamps: 0:00 The Crisis: Why Jakarta is Sinking 3:15 Phase A: Shoreline Reinforcement 9:21 Phase B: Offshore Megaproject 13:29 Phase C: Final Enclosure 14:16 Water Management & Pumping ⚠️ IMPORTANT: ABOUT THIS VIDEO ------------------------------------------------------------------- This is an educational documentary analyzing confirmed public infrastructure plans (NCICD Phase A & the 575 km Pantura extension) based entirely on open-source research.
