The Bagel Underground Tank is the ideal storage solution for those who have limited space on their properties or who want to hide their storage tank out of sight. Able to hold up to 5,000 litres of rainwater, it is one of our larger options that is easy to install thanks to its low-profile and lightweight design. It does not require fencing or shoring of the excavated area if the excavation is less than 1500mm (1.5m). Suitable for installation in load bearing applications, the tank can be installed at any stage in the building process and can be easily combined with other Toroid underground water tanks to achieve a greater liquid storage capacity. This tank is engineered from high-quality materials for enhanced durability and can be used for the detention and retention of water in accordance to local council building requirements. The Bagel Tank is accredited to the poly water tank manufacturing standard (AS4766) and to the septic tank standard for the burial of tanks underground (AS1546.1).
