What component is used to supply water to an elevated tank?

• A. Riser
• B. Pump
• C. Valve
• D. Reservoir

Answer: (A)

The vertical supply line that carries water up to an elevated tank is called a riser. It serves as the conduit from the ground-level distribution system or pump to the tank, enabling water to be delivered to the elevated storage so gravity can maintain pressure in the distribution system. A pump may be used to move water to that elevation, but the component that actually supplies water upward into the tank is the riser. A valve regulates flow, and a reservoir is a storage facility, not the delivery line. So the riser is the correct choice.
