What is typically found on top of horizontal underground storage tanks and cut and cover tanks that store jet fuel?

The presence of a pump house on top of horizontal underground storage tanks and cut and cover tanks that store jet fuel is crucial for several reasons. A pump house provides a controlled environment for fuel handling operations and houses the necessary mechanical equipment for moving the fuel, such as pumps and valves. This ensures that the fuel can be efficiently transported to and from the tanks while also maintaining safety standards.

Additionally, a pump house contributes to the stability and integrity of the tank, as it is designed to manage the potential fluctuations in pressure and volume due to the fuel's movement. The structure also offers a protective barrier against environmental factors and unauthorized access, further enhancing the safety of the fuel storage system.

In contrast, a concrete cover may be used for certain applications, but it does not typically serve the specific functional requirements associated with pump operations. An open air shed could provide cover but lacks the secure and controlled environment essential for handling jet fuel. The option of having nothing to prevent tank collapse fails to recognize the structural necessities and safety protocols required for storing hazardous materials like jet fuel.
