Our Underground Water Tank collection offers a sophisticated solution for water storage where space is at a premium or visual impact must be minimized. By moving your water storage below ground, you reclaim your garden or commercial site's surface area while benefiting from a system that is naturally insulated and protected from the elements. From simple domestic rainwater collection to massive industrial fire-fighting reserves, these tanks are the "hidden" heroes of modern water management.
One of the primary advantages of burying a water tank is the consistent environment it provides. Because the tank is shielded from sunlight, algae growth is virtually eliminated. Furthermore, the surrounding earth keeps the water at a steady, cool temperature throughout the year. This is particularly beneficial for Potable Underground Tanks, as it minimizes the risk of bacterial growth and ensures drinking water stays fresh and palatable.
Installing a tank underground requires specialized engineering to withstand the weight of the soil and the pressure of groundwater. Our range includes:
Shallow Dig Tanks: Designed with a low-profile shape to minimize excavation depth, saving on installation time and costs.
Ribbed Reinforcement: High-strength, moulded ribs ensure the tank remains structurally sound under ground pressure.
Adjustable Access: Telescopic necks and various lid options (pedestrian or vehicle-rated) allow for a seamless finish at ground level, regardless of the burial depth.
Underground tanks are the foundation of high-efficiency Rainwater Harvesting Systems. By collecting runoff from roof gutters, these tanks can supply water for garden irrigation, car washing, and even internal non-potable uses like toilet flushing and laundry. We offer comprehensive kits that include filters, calmed inlets, and submersible pumps, making it easy to transition to a more sustainable and cost-effective water supply.
With over 20 years of experience, The Tank Shop understands that an underground installation is a significant project. We work with leading manufacturers like Graf, Atlantis, and Enduramaxx to provide not just the tank, but the technical expertise required for a successful install. Whether you need advice on ground conditions, pump selection, or structural requirements for driveways, our team is here to ensure your underground storage system is built to last a lifetime.
