Which type of water pressure must be maintained to ensure adequate service during peak flow periods?

Which type of water pressure must be maintained to ensure adequate service during peak flow periods?

• A. Maximum
• B. Normal
• C. Minimum
• D. Low

Answer: (C)

Keeping water pressure above a minimum level is essential during peak demand. When many customers draw water at once, pressures can sag; having a defined minimum pressure ensures there’s still enough force to deliver water to all service connections, including higher elevations and distant parts of the system. This avoids extended low-pressure periods that could disrupt service, hinder firefighting capability, and affect water quality. Maximum or normal pressures don’t guarantee service under peak flow, and low pressure is the problem you’re preventing by maintaining the minimum.
