Since 1970, Modutank Inc. has offered a selection of large capacity rectangular water storage tanks and secondary containment systems suitable for most large capacity tank, water, chemical, fuel containment and seismic requirements. Composed of modular steel parts and fitted with various liner materials, our large capacity tanks feature rapid bolt-together assembly with hand tools. These large storage tanks can be installed free- standing on level, compacted surfaces or permanently anchor-bolted to concrete footings. Modularity assures a wide range of sizes and capacities. Furthermore, our flat panel tanks can be configured in square, rectangular or special shapes for irregular sites. Floating covers, steel covers, double liners, inlet and outlet fittings, leak detection, drains, vents and other ancillaries are available.
