How Saudi Arabia Built 14,217 km of Giant Pipes Across the Desert. Mega Construciton Documentary

Most of Saudi Arabia receives very little rainfall, yet millions of people rely on fresh water every day. This mega engineering documentary reveals how seawater becomes drinking water through intake systems, screening, filtration, reverse osmosis, remineralization, and disinfection. But the real challenge begins after desalination: moving water across harsh desert terrain through giant steel pipelines, pumping stations, valves, storage tanks, monitoring rooms, and corrosion protection systems. From factory-made pipes to offshore intakes, field welding, brine management, solar-powered desalination, and wastewater treatment, this video shows how engineering created an invisible river for modern desert cities.
