Containment Sumps

Fuel and Oil Tank Secondary Containment Sumps are an excellent way to store and contain hazardous materials on your site. Built with a containment capacity of 360 gallons, these sumps are rated for effective containment of 275 gallon tanks. This allows materials to be stored in a container that is rated to hold 110% of the liquids being stored in your tank.

Containment sumps are made from a high resistance poly exterior that provides effective resistance to rain, corrosion, rust, dirt and sand. Their robust exterior makes them equipped to withstand outdoor exposure and hold up to chemicals in the event of a spill. Additional sumps are available with flexible materials and storage sizes for 500, 550 gallon and 1000 gallon tanks.
