If a storage tank is used as water supply, what design requirements must it meet?

• A. It must meet the same water supply requirements as other sources.
• B. It must be designed, protected, and tested to meet the pump’s water supply requirements.
• C. It must be kept empty during testing.
• D. It must be located outside the building.

Answer: (B)

When the fire pump’s water supply comes from a storage tank, that tank has to be configured specifically to meet the pump’s demands. The idea is that the tank isn’t just any water source; it must be designed, protected, and proven by testing to deliver the exact quantity and pressure the pump requires when it starts and runs. Designing for the pump’s water supply means sizing the tank and its connections so the pump can draw water without dropping pressure or starving the suction, and ensuring the fill rate and volume are sufficient for anticipated fire-demand scenarios. Protecting the tank covers keeping the water clean and free from contamination, and safeguarding the structure and fittings from damage or tampering so the supply remains reliable. Testing confirms that, in actual operation, the tank can deliver the needed flow and pressure to the pump under expected conditions. So the correct requirement is that the storage tank be designed, protected, and tested to meet the pump’s water supply requirements.
