The Donut Underground Tank is the right water storage container for those who have limited storage space. It has a low-profile design that allows it to easily install under your property, and it can hold up to 3,000 litres of liquids. The tank can be installed at any stage in the building process, and its relatively lightweight frame allows for on-site movement and straight forward installation. Able to be combined easily with other Toroid underground water tanks to achieve almost any required capacity, a full range of accessories is available for the installation of the tank in single or multiple water tank installations. Built with the durability to withstand harsher demands, this tank is ideal for anyone who's looking for a central rainwater storage area that doesn't take up too much room. The Donut 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).
