Advanced Underground Rainwater Tanks: Pure and Safe Storage Solutions with Tankless

At Tankless, we take pride in taking the concept of underground water storage to the next level, and that applies to our underground rainwater tanks as well.

Our underground rainwater tanks are meticulously designed to ensure the highest level of purity and safety.

Each tank is fully enclosed and equipped with advanced filtration systems, guaranteeing that only clean and contaminant-free water enters the storage tanks.

With engineer-certified designs, our tanks provide the utmost security, remaining impenetrable even to pets.
Underground rainwater tanks like the ones we offer at Tankless offer several benefits, including:

    • Water Conservation: Underground rainwater tanks help in the efficient use and conservation of water. They collect rainwater runoff from rooftops, which would otherwise be lost or wasted. This collected water can be used for various purposes, such as gardening, irrigation, toilet flushing, and laundry.
    • Space-saving and Aesthetically Pleasing: One significant advantage of underground rainwater tanks is that they don’t take up valuable space on the surface of your property. These tanks are buried beneath the ground, which means you can use your outdoor space more effectively. This can be particularly advantageous for smaller properties or areas with limited space.
    • Protection from Evaporation and External Factors: Underground rainwater tanks provide better protection against evaporation compared to above-ground tanks. Being shielded from direct sunlight, the water stored underground is less likely to evaporate quickly, ensuring that the stored water remains available for longer periods. Moreover, our first class underground rainwater tanks are less susceptible to temperature fluctuations, reducing the risk of algae growth and bacterial contamination.

    The Success Story Behind Tankless...

    Did you know the only part of the World Trade Centre located next to the Hudson River that remained in tact after the terror attack was the Bentonite water proofing known as the 'Batch tub' that was built around the foundations to prevent the Hudson River from flooding the building. There was real fears that if the Bentonite bath tub structure would subside it would flood the basement & also the Subway rail system that was directly below the twin towers. Thousands of lives were saved in the hours after the attack because the 'batch tub' held strong.

    Underground Tankless system has used Bentonite clay liners since 2008 as part of the water proofing system that has stood the test of time through earthquakes, floods & droughts.

    Tankless also recognised that Ag pipe designed for collecting water to drain wet soggy areas was also perfect for water storage when combined with pillars of rock screenings & filtration provides a bullet proof system under a lawn, vegetable garden or driveway.
