Some water-based fire suppression systems include ? because of uncertain reliability of the municipal water supply.

• A. Water reservoirs
• B. Backflow preventers
• C. Booster pumps
• D. Water meters

Answer: (A)

The main idea is guaranteeing a dependable water supply for a fire suppression system when the municipal mains can’t be trusted. Having a water reservoir on site provides a stored volume of water right where the system needs it, so the system can deliver its required flow even if city supply or pressure is unreliable. This stored water often works alongside a fire pump to maintain the necessary pressure and flow to sprinklers or standpipes during a fire, ensuring the system remains effective without relying solely on municipal feeds. Backflow preventers are about stopping contaminants from entering the potable water supply, not providing extra water during a failure. Booster pumps help with pressure, but they don’t guarantee a sufficient volume if the external supply is unreliable. Water meters track usage, not supply reliability.
