Direct pumping water systems are those in which water

• A. Is pumped directly into the water distribution system
• B. Is pumped into storage tanks before distribution
• C. Is pumped only during peak demand
• D. Is pumped to hydrants only

Answer: (A)

Direct pumping means water is pumped directly from the source into the water distribution system without first being stored in tanks or reservoirs. This setup provides immediate delivery to the distribution mains and hydrants as demand occurs, assuming the source and pump capacity can meet that demand. Pumping into storage tanks before distribution adds a buffering step, storing water before it enters the mains, which is not the same as direct pumping. The other descriptions don’t define direct pumping: pumping only during peak demand implies a control strategy rather than the absence of storage, and pumping to hydrants only suggests limited delivery rather than feeding the entire distribution system.
