An MWS Apparatus that pumps the water from their tank directly into the fire pump of the attack pumper is called:

• A. Direct Pumping Operations
• B. Nurse Tanker Operations
• C. Relay Pumping
• D. Draft Pumping

Answer: (A)

Direct pumping operations occur when the Mobile Water Supply unit uses its own pump to push water straight from its tank into the attack pumper’s pump. The water flows directly from the MWS pump into the pumper’s intake so the attack engine can discharge without the pumper needing to take on water into its own tank first. This setup is fastest for getting water to the firefighting engine and reduces intermediate steps. Nurse tanker operations would involve the nurse tanker supplying water to the attack engine’s tank or to the attack pumper in a way that the pumper then uses its own pump, not a direct feed into the pumper’s pump. Relay pumping adds multiple pumps in series to move water farther or raise pressure, and draft pumping involves pulling water from an external source (like a pond) into the pump. The described arrangement matches direct pumping operations.
