If your property doesn't have enough space above ground for a water tank, then you can try using all that potential space below by installing the Waterplex 3000 Litre Donut Underground Water Tank with Trafficable Lid as a dependable rainwater storage option that you can install out-of-sight. The installation process is incredibly straightforward and can be done at any stage in the building process. The low-profile water tank is only 1200mm high (1.2m), can be installed with a minimum excavation of 1400mm, and does not require fencing or shoring of the excavated area if the excavation is less than 1500mm (1.5m).

The Donut Underground Water Tank with Trafficable Lid can be used for a variety of different applications once it's installed. It can act as a detention tank for rainwater to meet local council building requirements, function as a rainwater tank for irrigation or reticulation back into the home to meet local, state, and federal requirements or guidelines, or operate as a retention tank to hold water to meet local council requirements. In order for this to work, the interconnection foot on the tank is also the foundation of a retention/detention system. By drilling a hole to match the council-specified discharge rate (i.e. orifice plate) in the interconnection foot and positioning the overflow pipe at the desired storage level, an effective 100mm retention/detention system can be created.

This water tank is very cost competitive when compared with other polyethylene underground water tanks, and it is accredited to the polyethylene water tank manufacturing standard (AS4766) and to the septic tank standard for the burial of water tanks underground (AS1546.1). Suitable for installation in load bearing applications, it is one of the few underground watertanks approved by Housing NSW for installation in state government housing estates.
