Original Note:
These water ballast tanks are used to simulate varying loads during flight tests. https://www.airliners.net/photo/Airbus/Airbus-A380-841/1549782 During testing of a new airplane, barrels filled with water serve as a ballast system to test the center of gravity on the ground and during flight. The barrels can be moved to test the system. https://www.wired.com/2010/02/peek-inside-boeing-747-8/
