Dear Customers,

Between the months of October and February we start to experience longer lead times for production. With an ever-increasing demand for our products we would suggest placing your Water Tank purchase as soon as possible.

During October to December our Steel Water tank range can experience delays up to 8 weeks. Order early to avoid these delays.

The sooner you order your Water Tank the better chance you will have of receiving your water tank before Christmas closure.

We can produce rain water tanks in a wide variety of colours and sizes, ranging from small to large water tanks. Simply choose the water storing capacity you require and we can provide you with a solution that holds anywhere from 500 litres right through to 50,000 litres.

The Benefits of Installing Rainwater Tanks

The initial costs of installing rainwater tanks on your residential or commercial premises may be off-putting, but there are innumerable long-term benefits in doing so. They allow you to save significant amounts of money and give you the opportunity to lead a more self-sufficient and sustainable lifestyle without having to worry about public water systems. The specific benefits of using rainwater tanks in Melbourne include:

  • Rain water is free of chemicals and other impurities such as chlorine and fluoride. This usually means that the water tastes better than tap water and is more beneficial for your health.
  • Rain water is far cheaper than using and relying on public water systems. It can be used for residential applications such as washing the car, washing dishes, doing the laundry, watering plants, filling the pool, and even flushing the toilet. This helps to reduce the amount you pay on your water bills.
  • Rain water tanks are a socially responsible and environmentally friendly alternative, minimising the strain placed on stormwater systems and reducing the need to construct new dams. They can also be used to mitigate the effects of water restrictions in areas suffering from water shortages.

The Different Types of Water Tanks

Water tanks are made from different materials and are available in a variety of configurations. Depending on your needs, some of these may be more suitable than others, which is why you should get in touch with our team of experts who can help clarify things and point you in the right direction. Whether you’re looking for a slimline water tank or a polyethylene water tank, there’s no shortage of options to choose from at All Oz Water Tanks. We can provide the following types and sizes of rainwater tanks in Melbourne:

  • Poly Water Tanks – These are an affordable choice while maintaining high safety and durability standards. Poly rainwater tanks are relatively lightweight, durable and resistant to UV rays.
  • Steel Water Tanks – These are strong and sturdy options that are corrosion resistant and sustainable. These provide a great solution for harvesting, storing and using rainwater to its fullest potential.
  • Slimline Water Tanks – These rain water tanks are designed for spaces with limited room and feature qualities that provide ultimate strength and durability. They can be used to store anywhere between 600 litres and 7,000 litres of water.
  • Round Water Tanks – These are designed to store anywhere between 500 litres and 29,000 litres of water. They feature a deep corrugated profile, extra wide sheets, and minimal seams.
