5,000L Slimline Water Tank
The 5,000L Slimline Water Tank is built for sites where a standard round tank won’t fit — narrow side passages, tight courtyards, or space-constrained builds. Its slim profile delivers serious water storage without sacrificing usable yard space, backed by a 7-year warranty and manufactured to the highest quality standards.
When delivered to site, suitable lifting equipment is required to unload (e.g. forklift).
- Fits where round tanks can’t — a slim profile designed for narrow side passages and tight sites.
- One-piece build, no joins or seams — built to last, with moulded hand grips for easier positioning.
- Blends into any home — available in up to 17 Colorbond® colours to match your home’s exterior.
