The most popular rainwater tank in Perth residential homes.
Made from either Poly (polyethylene) or Steel. These tanks are designed to fit under a home’s eaves or down the side of the house.
Perfect for those narrow areas where a standard round tank will not fit. These tanks will still give you access around them whilst storing precious rainwater for your house and garden.
‘Water Capture’ can expertly install these tanks to your existing home or new build, or simply deliver the tank only.

POLY SLIMLINE TANKS
Made in Western Australia and can be delivered anywhere in the state.
