When more commercial and residential properties and infrastructure are threatened by the effects of flooding, the benefits of greater protection are worth the cost of the proper emergency response equipment. It is important that at-risk communities have the necessary equipment for emergency quick response when flooding events occur. This includes flooding due to tidal surges and excessive rainwater from storm-related events, rising rivers and streams, levees breaches and infrastructure sump pump inundation and failures. High volume flood mitigation equipment that allows quick response and ease of deployment can mean saving lives and property, as well as minimizing business and infrastructure service interruption.

Flooded Subway System

Chief Fire offers stationary and mobile high volume flood mitigation pump systems which utilize the world’s lightest and most compact floating submersible source pumps. Chief is the only manufacturer that offers composite technology in the construction of our floating submersible units that make them extremely lightweight and corrosion proof, enabling their use in both fresh and saltwater applications. The power units for these pumping systems may be located remotely from their dewatering points, between 100 and 200 feet, which maintains the power unit, controls, and the operator in a safe location. Because these systems use a biodegradable hydraulic fluid for enhanced operation, the equipment may be used in environmentally sensitive areas with little or no adverse impact.


The compact and lightweight characteristics of these systems allow quick, emergency response, setup, and breakdown operations, and offer deployment flexibility over a variety of terrain or structural configurations. Because these are floating submersible pumps, no vacuum priming is needed, thereby eliminating any high lift restrictions associated with centrifugal pumps.
