The 220 Gallon Heavy Duty Vertical Double Wall Plastic Storage Tank provides primary and secondary containment in one product and is designed for commercial and industrial use. If your containment liquid is subject to EPA regulations, this tank is a great option. The double wall tank design allows safe confinement of hazardous chemicals and liquids, such as calcium chloride, sodium hydroxide, fertilizers, urea, used motor oil, liquid polymers, surfactants and lubricants that could cause major environmental damage if accidentally discharged or spilled. The inner tank is completely and securely encased within the secondary tank allowing it to be compliant with 40CFR-264.193 requirements. The secondary containment or outer tank can accommodate 110% of the inner tank’s volume should the primary tank face an event. Sealing of the outer tank keeps elements from entering the enclosure during deployment or usage. By utilizing an integral secondary containment design, space is saved, and there is no need for additional containment costs or containment product additions.
