 The draft tube is anchored to the sea bed at its bottom side and top side to floating pontoons at the sea surface.The flexible draft tube would not collapse as its inside pressure is more compared to outside pressure when the colder water is pumped to the sea surface.Middle east, north east Africa, Indian subcontinent and Australia can get relief from hot and dry weather in summer season, also prone to erratic rainfall, by pumping deep sea water to the sea surface from the Persian gulf, Red sea, Indian ocean and Pacific ocean respectively.
