1. Low Cost Installation
The Toroid Underground Water Tank has a low profile reducing the amount of excavation depth required. Saving on excavations and ballast costs and reducing the chances of hitting troublesome hard rock or ground water.
2. Safe Working Environment
The most Water Tank installations do not exceed beyond 1500mm and installations of this type do not require perimeter fencing or shoring as required by law (Worksafe’s Working at Depths Guideline (Mines Act – Trenching 1982). Due to Toroids, low profile Water Tanks allows for safer, easier and quicker installations.
3. Done and Dusted
The Toroid Water Tanks Installation is can occur in the early-preliminary stages of a building site construction – easing the congestion at the later stages of any building project. Installed can occur anywhere on site – even in the set-back zone of the house or high traffic areas and driveways. They can also be installed in high-traffic areas, such as under the driveway (before building commences).
5. Water Table
Since plastic materials are lighter than water the problem is that an empty water tank would float should it meet ground water. To avoid this problem, The Toroids Patented Compression Ballast System is cleverly positioned on top of entire tank to act as a dead weight providing a very effective protection against the “hydrostatic lift” problem.
5. Flexible installation
Since every installation has its own unique conditions VRM has developed ‘easy to use’ range of accessories to ease installation and situations.
