Preparing for Your Poly Water Tank Delivery

When you order a Bushmans poly water tank, our job does not end at the factory. Poly tanks range from compact 1,000L round tanks to large-capacity 50,000L+ storage solutions, and each delivery requires different site preparation depending on the size and your access conditions. Our drivers are experienced with the full range and will work with you to get your tank positioned safely.

Before your poly tank arrives, make sure you have:

  • A clear, firm access path wide enough for a delivery vehicle and crane truck where required
  • A level, compacted base prepared to the correct dimensions for your tank size
  • Confirmed where you want the tank positioned before the driver arrives
  • Any plumbing connections or inlet fittings ready so installation can proceed without delay

Bushmans provides full water tank delivery in Australia, with drivers experienced in delivering to rural properties, tight residential blocks, and commercial sites. From access checks to final placement, we make sure your poly tank lands exactly where it needs to be.

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.

Bushmans Sun Tough Poly Water Tanks

If your property gets a lot of sun, Sun Tough poly water tanks are built for those conditions. The material and colours are selected for UV performance. Tanks are made in Australia and meet potable standards. Steel remains a strong option for some sites. Poly offers value, does not rust, and often does not need a slab. Sun Tough adds longer resistance to sun, so you can choose poly with confidence in hot, sunny locations. Our Customer Care team can help you choose the right capacity for your roof area and use, and arrange delivery, placement, and fittings.

At Bushman Tanks, our poly rainwater tanks have a 10-year guarantee and are suitable for a wide range of applications including domestic use when water needs to be collected or stored, on commercial buildings to catch stormwater runoff and for use in the factory, warehouse or processing plant. Bushmans poly water tanks are designed and built to last well past the warranty period so you can rest assured knowing that your water is safe and secure.

Key Features of our Poly Rainwater Tanks:

  • Maximum strength – Made in one piece
  • Bushmans Sunsmart® Raw material for longer life
  • Simple and easy to install
  • 10-year Bushmans warranty
  • Key fittings included
  • Architectural and aesthetic design
  • Designed to comply with AS/NZS4766 tank standard
  • UV-resistant for Australian conditions
  • Large range of poly tank colours and sizes
  • All of Bushmans poly rainwater tanks are fully approved for potable water

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. Whether you need a small tank or a large poly water tank – be it for domestic, agricultural or industrial use – Bushmans can meet your needs.Our slimline range of tanks range in size from 1000 litres to 5000 litres.

Rainwater Tank Regulations in Australia

Before installing a rainwater tank, it’s important to understand the regulations that apply in your state or territory. Bushmans has created a detailed guide to Australian water tank regulations to help you stay compliant and get the most from your tank. Here’s a quick overview of the key requirements across the main states and territories, with links to official government resources for full details.

New South Wales
In NSW, most homes can install a rainwater tank without council approval, provided it meets specific size, height and location rules. Tanks connected for internal use (to toilets or laundry) may require plumbing approval.
Read more on Sydney Water – Rainwater Tanks

Queensland
Queensland councils encourage rainwater harvesting, but approval requirements depend on tank size and plumbing connections. Maintenance standards also apply to ensure safe household water use. See the full details from Brisbane City Council and the Queensland Government PDF guide.

Victoria
Victoria promotes rainwater tanks for water savings and sustainability. New homes often require rainwater tanks to meet building permit conditions. Proper installation and maintenance are key to maximising water use.
Read more at Victoria Government – Rainwater Tanks.

South Australia
In South Australia, rainwater tanks are compulsory for new homes and major extensions, with minimum capacity requirements. Placement and plumbing must comply with building standards.
See guidance from the City of West Torrens and the SA Government – Rainwater Tanks.

Australian Capital Territory
In the ACT, planning approvals may apply depending on tank size and location. Building standards outline installation requirements to ensure safety and water quality.
See the official ACT Government Rainwater Tank PDF.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.

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.
