Toroid underground water tanks from Tankmasta

Tankmasta's award winning Toroid Underground water tanks are the perfect solution for homes where presentation and space are the main contributing factor in purchasing a water storage tank.

The best looking tank you'll never see!

With proven reliability, these structurally sound underground tanks have been tested to a weight bearing of 22tonne, holding a specific gravity of 2.1. The Tankmasta Toroid range come in two size, the 3,000lt Donut and 5,000lt Bagel, appropriately named based on their unique shape.

Very popular in the building and trade industry, the Donut and Bagel are low profile, easily installed underground tanks. The optional cone riser facilitates easy installation, allowing the tank to be buried and construction to continue around the building site leaving the final collar and lid fitting until final levels have been determined.
