Which statement describes Direct Pumping Operations?

• A. The MWS pumps water from its tank directly into the attack pumper's pump
• B. The attack pumper pumps water into the MWS
• C. Water is transferred by hydrant to MWS
• D. The MWS uses a discharge line to supply water to a distant tanker

Answer: (A)

Direct pumping operations use the water stored in the Mobile Water Supply’s own tank and pump to feed the attack pumper directly, with a discharge line that connects into the attack pumper’s pump suction. This setup lets the attack engine start delivering fire water quickly without any intermediate transfers or storage steps. The water path is simple: MWS tank → MWS pump → discharge line → attack pumper suction → attack pumper → fire streams. It’s efficient for rapid deployment when the MWS is close to the attack pumper and you want to minimize connections and transfer losses. The other scenarios involve moving water into the MWS, transferring via hydrant, or sending water to a distant tanker, which are not the direct feed arrangement described here.
