Which term describes a water supply system that is supplied directly by pumps rather than elevated storage tanks?

• A. Direct Pumping System
• B. Combination System
• C. Water Main
• D. Steamer Connection

Answer: (A)

The question focuses on how a building’s fire-water supply is delivered: whether water is stored in elevated tanks or pumped directly into the system. A direct pumping system means water is supplied straight into the fire protection piping by pumps from the water source, with no elevation or ground storage tanks providing pressure. The pumps actively push water into the system as needed, so pressure and flow depend on pump operation and demand rather than gravity. This distinguishes it from other setups. A combination system uses both pumping and storage tanks to provide pressure, relying on stored water as well as pumped delivery. A water main refers to the public distribution line supplying water to an area, not a specific internal fire-protection configuration. A steamer connection is an external inlet firefighters use to supply water to a standpipe or sprinkler system during operations, not a description of how the building’s water supply is fed.
