Available Liner Types


Unique 100,000 gallon ModuTank Inc. storage tanks, proven internationally for more than 50 years, are the ideal solution for your liquid storage needs. They feature compact, galvanized steel components designed for rapid bolt-together assembly in hard-to-reach indoor/outdoor locations. Our tanks are perfect for sites with limited access. Included footing plates allow free-standing, quick installation on most flat, level surfaces with minimal or no formal site prep, or, if available, they can be anchor-bolted to concrete foundations. One-piece membrane liners chosen for your specific liquid, line the tank’s interior and simultaneously shield the galvanized components and protect the stored contents from contamination, and leakage into the environment.

While 100,000 gallons is a standard size in our product line, our modular tanks are available in sizes ranging from 500 to over 2,000,000 gallons. Modutank Inc. products offer the lowest containment costs, compared to Others, when considering the tank, shipping, site preparation, and installation costs.
