When higher volumes of non-potable water storage are needed, the Platin XXL Flat Tank delivers capacity without compromising on installation depth.
Designed for large residential, commercial, or agricultural use, this extra-large underground tank is ideal for storing rainwater, grey water, or other non-potable sources for reuse.
Despite its high capacity, the flat, modular design reduces excavation costs and allows for easier placement in tight or shallow locations.
Its rugged polyethylene shell is engineered for underground stability, including vehicular loading when installed with appropriate covers and surrounds.
Flexible accessory options support customised installations for various water reuse systems.
