When a water source does not have adequate elevation to create proper pressure for gravity flow, it is necessary to use:

• A. Larger size pipes in the mains
• B. Pumps to raise the systems pressure
• C. Computer controlled pressure regulators
• D. A booster line

Answer: (B)

When water pressure is driven by gravity, the pressure you get depends on the height of the water column above the outlet. If the source doesn’t have enough elevation, gravity alone can’t push water to the needed firefighting pressures. The way to fix this is to add energy to the system with pumps, which raise the water’s pressure so hydrants and standpipes receive the required flow and pressure. Larger pipes might improve flow by reducing friction, but they don’t increase static pressure when head is insufficient. A regulator can protect or limit pressure, not raise it, and a booster line is a supplementary path that still relies on pumping. So, using pumps to raise the system’s pressure is the effective solution.
