Which is the oldest and simplest type of water pressure booster system?

• A. Elevated-Tank System
• B. Hydropneumatic System
• C. Forced Circulation System
• D. Recirculation System

Answer: (B)

Booster systems provide pressure by stored energy rather than height. The hydropneumatic arrangement uses a storage tank charged with air to create that pressure. As water is drawn, the compressed air pushes water out, maintaining a steady pressure with only occasional recharging by the pump. This simplicity—one tank, an air cushion, and basic valves—made it the earliest practical booster option for many settings. Elevated tanks rely on gravity from height to give pressure and are not a booster in the same sense, while forced circulation and recirculation setups add pumping or piping that increases complexity.
