Which statement best describes Water Supply Adequacy in sprinkler systems?

• A. Not enough water supply
• B. Adequate water supply
• C. Sufficient water for effective sprinkler operation
• D. Excessive water supply

Answer: (C)

Water supply adequacy means the available water source provides enough volume and pressure to let the sprinkler system operate as designed. In practice, that means delivering the required flow to all sprinklers for the necessary duration and maintaining sufficient pressure at the most hydraulically remote heads. If the supply falls short, sprinklers may not discharge adequately, compromising fire control. That’s why the statement describing it as “sufficient water for effective sprinkler operation” best captures the idea. The other phrasings either imply undersupply, oversupply, or are too vague to describe the needed capability.
