Our Double Wall Day Tanks provide primary and secondary containment in one space-saving integral unit. Eliminating space wasting dike walls that may require confined space entry is a cost savings idea. The Double Wall Tanks can easily be moved as a unit to different plant locations with no additional special secondary containment requirement. The containment moves with the tank!

This system consists of a primary inner tank and secondary containment tank, with a capacity of 120% of the inner tank exceeding EPA standards and follows all secondary containment guidelines from local, state and federal regulations.

Inner tank dome overlaps the outer tank sidewall to prevent rain water, snow and debris from entering the secondary containment. This makes Double Wall Tanks a more cost effective solution for outdoor storage of chemicals because of elimination of the cost of pumping and the disposal of rain water. The construction cost of dike walls and expensive lining systems is eliminated as well as maintenance issues associated with polymer coatings.

The Double Wall Tanks in smaller sizes are ideal for day tanks. Molded in pump shelves are ideal for installing chemical pumps and metering equipment. This pump shelf recessed in the top of the tanks to contain small chemical spills.

The Double Wall Tanks in smaller sizes have a molded in sump in the primary tank which is located directly below the pump shelf. Suction lines can be lowered into the sump area which will allow for maximum drainage of the chemical with top discharge assemblies. Recessed lower fitting flat will allow fittings to penetrate through the secondary containment wall and into the primary tanks' sump. This feature allows full flooded suction for outlet assemblies.

The Double Walled Tanks have a built in squirt shield. If a rupture occurs in the sidewall of the primary tank, the secondary wall prevents personal injuries from chemical spills or an environmental spill.

An automatic electronic leak detection system can be installed in the interstitial space meeting all regulations. The leak detection can be tied into a high level alarm and direct read out of the real time capacity of the tank.

Molded-in forklift access allows for easy movement in tight spaces.

These unique tanks are built
