As for this question,we will tell you we can make ballast water tank which can store water and use in ship and bridge preloading, railway and highway bridge construction etc.
Ballast water is water carried in ships’ ballast tanks to improve stability, balance and trim. It is taken up or discharged when cargo is unloaded or loaded, or when a ship needs extra stability in foul weather.
When ships take on ballast water, plants and animals that live in the ocean are also picked up. Discharging this ballast water releases these organisms into new areas where they can become marine pests.
