Why use a rainwater tank?

Water covers roughly 70% of the earth; however, only 3% of this water is fresh water and two-thirds of this freshwater is locked away in ice and glaciers. As such, water is fast becoming a scarce resource. Rainwater tanks in Australia minimise water wastage, retain water close to the source and reduce the strain on stormwater drainage systems. By using a poly rainwater tank, you are saving money and doing your part for the environment at the same time.

Poly tanks are some of the most robust water storage products. These rainwater tanks have extremely high longevity in the field and are particularly resistant to degradation compared to water tanks made from other materials.

Round rainwater tanks are the most common tank used however slimline tanks are popular as they are able to fit into narrow spaces alongside houses and other buildings. These poly water tanks both use the latest in design, manufacturing and quality assurance to ensure that your new purchase can stand the test of time.

Bushmans have been operating since 1989 and have the experience to give us in-depth knowledge and expertise in manufacturing tanks. We are committed to finding a tank that meets your specific requirements. Our water tanks vary in size, shape and colour. Sizing starts from small tanks at 1,000L. These rainwater tanks are ideal when there is minimal space. Our largest poly tank is 46,400L – perfect for rural or industrial applications or when there is a need to store or manage a large amount of water.

Advantages of Poly Rainwater Tanks

  • Strong and robust – Our poly rainwater tanks are tough and resilient. They can withstand even the toughest conditions – even if hit by a hammer, the poly tanks do not dent or break.  This is made possible using seamless architectural design – no joining points results in no weak points.
  • Poly water ranks have stood the test of time – in the field for many years with an excellent service life.
  • Very easy to install – although we recommend having professional help assist with the installation, our poly tanks are so easy to install that we have created instructions which can be found here.
  • Come in a wide range of colours – our poly tanks come in a variety of colours, so your new poly water tank can effortlessly become a part of your home or business.

Bushmans own Sunsmart® polyethylene raw material to make our Suntough® range of plastic tanks.

  • This gives longer life in the sun – our Sunsmart® material will help protect and prevent the polyethylene tank from aging.
  • Reinforces and strengthens the walls – this provides an extended lifetime for the poly tank.
  • Reduces colour fading – our poly rainwater tanks will stay looking good.
  • Positive environmental benefits
  • Less reticulated water use – you will have access to a natural water supply close to your home.
  • Eliminates wasted water going down the drain – less wastage means your water costs will be reduced and you will be using a natural resource.
  • Stormwater retention – harness a natural resource in the form of storm water and put yourself in a position to gain value from storms.
  • Less energy – reduce your energy expenditure by switching from water pumps to a poly water tank
  • Self-sustaining – regain control by switching to a self-sustaining method of accessing and using water.
  • Positive environmental benefits – Reduce water waste, harness stormwater, and lower energy usage by switching to a self-sustaining poly tank solution.

There are several applications for poly water tanks in day-to-day life, primarily around the house, the farm, the business or in schools. Within the household, a water tank can provide a means by which to take pressure off the monthly water bills by providing you with a self-sustaining method of collecting and utilising rainwater. Similarly, on a farm, there is a definitive need for water whether it is being used for livestock, gardens, cropping or other uses around the farm.

At Bushman Tanks, we understand this innate need and our poly water tanks can help farmers achieve independence and make farm management easier. Businesses also have a need for a reliable source of water and our poly tanks can allow businesses to store water securely in a tank that can fit almost any environment or situation. Some of the potential uses for businesses involve stormwater management, on-site water supply, garden water, and using water in the production process.

At Bushman Tanks, we are proud supporters of the education system and acknowledge the important work teachers do in developing the future generations of Australia. Our polyethylene water tanks can be used in schools as a means of helping to teach children about sustainability and the importance of responsible water use with the increasing problem of water scarcity. We have been extensively involved in Landcare Australia’s initiatives centred around this topic.

Our durable poly water tanks are UV-resistant and designed to withstand Australia’s harsh climate, ensuring they provide a long-lasting, eco-friendly water storage solution.

Poly Water Tanks for Farms

On farms, water is essential for irrigation, livestock watering, and drought mitigation. Bushmans’ large poly water tanks are designed to meet these needs, offering sizes ranging from 10,000L to 46,400L. Key applications include:

  • Irrigation systems: Supporting subsurface and sprinkler systems for efficient crop management.

Differences between poly rainwater tanks and other types of tanks

When comparing poly tanks to tanks made from other materials like steel or concrete, the advantages are clear. Polyethylene tanks are lighter, easier to install, and less prone to damage from weather and corrosion. They are also more cost-effective and versatile. Unlike steel tanks, poly tanks do not rust, and unlike concrete tanks, they are resistant to cracking.

Poly tanks are also:

  • Seamless – Made from a single piece of polyethylene, reducing the risk of leaks
  • Impact-resistant – Strong enough to withstand blows without denting or cracking
  • Corrosion-resistant – Ideal for storing water in coastal areas or environments with high salt content

All our water tanks for sale are covered by the Bushman’s 10-year water tank guarantee, giving you confidence and peace of mind.

When considering the differences between the types of water tanks to purchase, it is important to understand the differences between materials such as plastic, steel, fibreglass, and concrete. Each material has its own advantages and disadvantages in terms of durability, corrosion resistance, and ease of installation.
