We provide you with choice when it comes to selecting the right rainwater tank or pump for your household or rural rainwater storage needs. Our products have been carefully selected to meet our strict standards, so you can be confident in the quality of the item you receive. We also offer customised tank and pump packages to save you money and give you everything you need in one place.

Water storage vessels are manufactured in different sizes and capacities. Slimline water tanks range from 1000 litres to 5400 litres in volume. They are perfect for a home garden on a small block or for installation down the side of a home, or for anywhere that space if limited.

As an alternative you can consider an underground water tank. We carry a full range of underground storage solutions made from poly or concrete. They are specially designed to be buried, and can be supplied with accessories for use under a driveway. Our underground poly water tanks are available in sizes up to 5000 litres. Concrete water tanks can be much bigger and are ideal for holding large volumes of water. We sell concrete tanks from 3800 litres to 22,500 litres. They are a great way to harvest rainwater and keep it neatly hidden from sight.

There are also a selection of bladder water tanks that can be installed underneath timber decking, or in other small areas. We supply large watertanks suitable for rainwater harvesting throughout most of Australia, not just in Sydney and New South Wales. We supply poly tanks up to 50,000 Litres, corrugated steel tanks to 30,000 Litres and steel panel tanks up to 375,000 Litres. If you want a water tank delivered to you in Victoria, Queensland or South Australia we can help you. In fact, we have just about every type of rainwater collection system available. If you cannot find the rain tank you want on our website, give us a call on 1300 88 94 90 and we will try to find it for you.
