What is the capacity of the lifter roof tank?

• A. Fixed capacity of 200,000 gallons
• B. Varies due to construction
• C. 8,500,000 gallons
• D. 50,000 gallons

Answer: (B)

The capacity of a lifter roof tank is notfixed; it varies because the tank is built to meet the specific project needs and site constraints. The interior volume depends on the shell dimensions—diameter, height, and any internal features or compartments chosen during construction. Different communities or facilities may require different storage amounts, so you’ll see a range of sizes rather than one universal number. The idea behind a lifter roof is about how the roof operates and access, not about locking in a single capacity, so there isn’t a single standard capacity that applies to all of these tanks.
