Tankmasta’s Underground water tanks were designed after recognizing a need in the industry for an underground tank that is structurally strong, resistant to hydrostatic lift pressure and easy to install.

These underground tanks are made from chemical resistant, food grade LLDPE resin, Toroids have been designed to withstand external forces with an S.G. of 2.1.  The design of the Toroid shape gives the water tank’s their superior strength. The central void allows the tank to be incorporated into heavy duty situations and the heavy rib profile allows the surface load to be transferred away from the tank itself. Accordingly, installations under driveways and garage floors are now possible as these Underground Tanks can be used in both foot and trafficable zones.

Another huge benefit of underground water tanks that the water is stored in an environment where the temperature does not fluctuate to extreme conditions.  The tanks are unobtrusive and are away from sight.

Underground tanks are usually combined with submersible pumps.  Please see the submersible pump options in the drop-down options.
