Varitank - Bolt-Together Storage in Hard-to-Reach Locations



varitank_1smModular VariTank components are designed for hand-carrying through doorways or other small openings for rapid bolt-together assembly in basements, tunnels, interior rooms and other hard-to-reach locations. VariTanks provide low-cost fluid handling for permanent or standby service indoors and outdoors. In addition, VariTanks can be quickly disassembled for relocation or storage.


Standard Varitanks are available in sizes based on 3’6” wide by 6’3” or 8”0” high modular panels. Customized heights are also available.

Installation Speed

A typical VariTank can be installed in a day by two workers using common hand tools. No special skills are required. Little or no ground preparation is needed. They can either be installed free-standing or anchor-bolted to new or existing concrete foundations.


Liners in reinforced 45 mil polypropylene, 30 mil XR-5 and potable water grade polypropylene are available.

Leak Detection Systems

Double liner leak detection with sight tube leak detectors is optionally available.


Inlet and outlet pipes can be installed over the top, through the bottom or through-the-wall or cover with flange fittings in factory cut holes. Flange fittings, hatches, leak detectors, ladders, vents, baffles and adjustable standpipes are available.


Covers are fabricated from type 304 or type 316 stainless steel. Floating and tarp type covers fabricated from various liner materials are also available.

Special Shapes

Virtually any shape utilizing right angles such as square, rectangle, “U”, “L”, “X”, etc. Custom Tanks can be assembled from VariTank’s unique modular components. This capability is especially useful for installations with irregular shapes or with special flow requirements.
