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 gardener on a small block to install down the side of their home, or anyone else short on space.

If you don’t have enough room, 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 which can even make them suitable for under a driveway. The 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 stock concrete tanks from 1000 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.

Your tank package can also be part of a grey water system that can recycle some of your water so it can be used in the garden or for toilets. Grey water is different from black water, which consists of toilet wastes and is highly contaminated. Grey water is not as highly contaminated and it can be recycled to save you money, and help the environment as well.

We supply watertanks suitable for rainwater harvesting to most of Australia, not just in Sydney and New South Wales. If you want a water tank delivered to you in Victoria, or in Queensland - we have you covered. 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 85 02 12 and we will try to find it for you.
