How many fresh water storage tanks are there on board?

• A. 2
• B. 1
• C. 3
• D. 4

Answer: (A)

Two freshwater storage tanks are used to ensure a reliable potable water supply on board. The two-tank setup provides redundancy—if one tank needs cleaning, maintenance, or isolation, the other remains in service so water is always available. It also keeps the distribution system steady, allowing water to be drawn from one tank while the other is being refilled, which helps maintain consistent pressure and supply to the crew areas. In practice, you’d monitor both tank levels and switch the feed as needed to maintain a continuous, safe supply.
