Large Secondary Containment Double Wall Tanks from Assmann Provide Capacities from 150 to 6550 Gallons

Features of Double Wall, Industrial Storage Tanks.

Large double wall secondary containment tanks.This polyethylene storage tank system consists of a primary inner tank and a secondary, locked-on outer tank with a capacity of 120% of the inner tank, exceeding EPA standards.

Assmann Corporation advises that using its Double Wall Tank system with a bottom sidewall fitting may not meet local codes for secondary containment, as tank contents could escape containment area in the event of fitting damage. Assmann also recommends that its Double Wall Tanks be fitted with a top suction line and foot valve to provide constant flow to the pump.

Inner tank dome of Double Wall Tanks overlaps outer tank sidewall to prevent rainwater, snow and debris from entering into the plastic containment basin. Tank accessories for Assmann industrial storage tanks.
