Since 1970 Modutank Inc. has manufactured bolted steel storage tanks and secondary containment systems suitable for most water, chemical, fuel containment and seismic requirements. We offer a variety of modular tank designs in a wide range of shapes with capacities from hundreds to millions of gallons, to meet the most challenging storage needs.

Bolted steel tanks are common solutions for storing virtually every type of liquid used in commercial and industrial applications, and are generally accepted as industry standards. Modutank Inc. rectangular water storage tanks offer considerable savings over site-built tanks through economical shipping, fast assembly, and low- cost, mass-produced galvanized steel parts.

Our flat panel tanks feature factory-fabricated components engineered for quick bolt-together assembly into square, rectangular, or special shaped units with right angle corners like the letters “L”, “T”, “S”, etc. This enables our tanks to be shaped and fitted to unique sites or meet special flow requirements. Equally suited for indoor and outdoor use, their compact tank components can be hand-carried through existing doorways, carried on staircases, and lifted via elevators for bolt-together assembly in hard-to-reach places. Rectangular tanks advantageously offer greater capacities than round tanks in tight indoor spaces.

Modutank Inc. rectangular bolted tanks can be installed free-standing on virtually any level, compacted surface or permanently anchored to concrete footings. Floating and steel covers, secondary containment double liners, inlet and outlet fittings, leak detection, drains, vents and other ancillaries are available. Furthermore, our modular tank components are engineered for efficient shipping and assembly or dismantling by untrained workers using common hand tools while following an illustrated installation manual. Heavy-duty galvanized steel components assure long maintenance-free service.
