Which method delivers water to the destination without pumping equipment?

• A. Gravity system
• B. Direct pumping systems
• C. Both gravity & pumping systems
• D. None of the above

Answer: (A)

Moving water without pumping relies on gravity to push the water from a higher point to a lower one. In a gravity-based distribution, water is stored in an elevated reservoir or tank. The height difference between that stored water and the points where people use it creates pressure in the pipes, so water flows through the network to homes and businesses without needing motors or pumps. Friction losses along the pipes reduce flow, but as long as the elevation head is sufficient, the system delivers water to the destination naturally. Direct pumping systems move water using pumps, which is why they don’t fit the “without pumping equipment” criterion. A gravity system can serve many destinations as long as the supply head is adequate; if you need to raise water to higher elevations or boost pressure beyond what gravity provides, pumping would become necessary.
