Rainwater tanks are a smart investment in South Australia. According to abc.net.au, South Australia had the eighth driest April in 2024 since record keeping began. With water scarcity being a persistent challenge in the region, especially in rural areas, residents are increasingly looking for ways to conserve water and manage it more efficiently. One of the best investments for homeowners and businesses in South Australia is installing a rainwater tank. These tanks not only help secure water supply during dry periods but also offer financial, environmental, and lifestyle benefits.

Here’s why investing in a rainwater tank is a wise decision for South Australians.

1. Water Conservation in a Drought-Prone Region

South Australia frequently faces periods of low rainfall, making rainwater collection an important resource. By capturing and storing rainwater, homeowners can reduce their reliance on mains water supplies. Rainwater can be used for various purposes, including:

  • Gardening: During times of low rainfall, many households have to cut back on watering gardens and lawns. A rainwater tank allows you to keep your plants healthy and vibrant without worrying about fines or penalties.
  • Toilet flushing and laundry: Installing a tank with a pump system allows you to use rainwater for everyday household chores, further reducing your dependency on potable water.
  • Drinking water: With proper filtration, rainwater can be used as a safe and sustainable drinking water source.

Given South Australia’s limited rainfall, having a rainwater tank helps ensure that your household remains water-secure during dry spells or when water restrictions are enforced.

2. Cost Savings on Water Bills

One of the most compelling reasons to invest in a rainwater tank is the potential for significant cost savings. By using rainwater for non-potable purposes (like flushing toilets, washing clothes, and irrigating gardens), you can reduce your reliance on mains water and cut down on your water bills.

In areas with high water costs, such as Adelaide, even moderate use of rainwater can lead to noticeable savings over time. Additionally, by relying less on mains water, households are protected against future price increases or supply disruptions.

3. Environmental Benefits

Investing in a rainwater tank is an environmentally responsible choice. By capturing rainwater, you’re reducing the demand for treated mains water, which takes energy and resources to pump, purify, and transport. Using rainwater helps:

  • Reduce stormwater runoff: In urban areas, heavy rains often lead to water running off roofs and streets, picking up pollutants before entering storm drains and eventually the ocean. By capturing rainwater in a tank, you can help reduce stormwater runoff, protecting local waterways and reducing the burden on stormwater infrastructure.
  • Decrease energy consumption: Treating and distributing mains water requires significant energy. By reducing your demand for treated water, you contribute to lowering the energy footprint associated with water consumption.
  • Promote sustainable living: Using natural resources wisely, such as rainwater, aligns with eco-friendly practices and helps mitigate the effects of climate change.

4. Independence from Water Restrictions

South Australia is often referred to as the driest state in the driest country on the driest inhabited continent. The last imposed water restrictions were in 2020. By having a rainwater tank, you gain a level of independence from these restrictions. You can continue to maintain your garden, fill your pool, or water your property using stored rainwater without violating any water use regulations.

5. Government Rebates and Incentives

In recognition of the importance of water conservation, the South Australian government and local councils have offered incentives and rebates for installing rainwater tanks in the past.  Check with your local council if any are still available. These programs aim to reduce strain on public water systems and encourage the use of alternative water sources. While rebates can vary by location and specific conditions, they often help offset the initial installation cost, making rainwater tanks an even more attractive investment.

6. Increasing Property Value

A rainwater tank can also be a valuable addition when it comes to selling your property. Prospective buyers increasingly view water conservation systems as an attractive feature, particularly in water-scarce regions like South Australia. A rainwater tank shows that the property is designed with sustainability in mind, which can be a significant selling point. This is especially true if the tank is plumbed into the home for practical use, such as in toilets or for garden irrigation.

7. Versatility in Size

Ri-Industries rainwater tanks come in four sizes to suit your property’s needs. Whether you live in a compact urban home or a sprawling rural property, we have a rainwater tank solution for you.

8. Climate Change Resilience

Climate change is expected to bring more unpredictable weather patterns, including both increased rainfall intensity and longer dry periods. Investing in a rainwater tank now helps future-proof your home against these changes. By capturing water during heavy rainfalls, you can ensure you have a supply during times of drought, making your home more resilient to the effects of climate variability.

Rainwater tanks are a smart investment for South Australians looking to conserve water, reduce their bills, and become more self-sufficient. With environmental, financial, and practical benefits, rainwater harvesting offers a sustainable solution to the region’s water challenges. Whether you’re interested in reducing your water bills, maintaining a lush garden through summer, or simply doing your part to protect the environment, a rainwater tank is an excellent addition to any South Australian home or property.

Rainwater Harvesting Will Help Conserve Water and Lower Costs

by Ri Industries

Rainwater harvesting is an excellent way to conserve water and lower expenses. The rainfall we’ve been seeing in South Australia makes this a great time to learn about rainwater harvesting and see if it’s something you’d like to do. 

First, let’s answer the question, ‘What is rainwater harvesting?’. Simply put, it’s collecting and storing rain for later use. So now, let’s take a look at how the water can be used and how it is collected. 

Harvested rainwater provides clean water where water is scarce or polluted. It can be used to flush toilets, do laundry, water the garden, wash cars, and more. However, if you want to be able to drink the water, the system must be designed, operated, and maintained to ensure the water quality is suitable. 

It’s often thought that rainwater harvesting is only done in rural areas. In fact, many urban households harvest rainwater to significantly lower mains water usage. According to www.sa.gov.au, “South Australian building rules require that new dwellings and some extensions or alterations, have an additional water supply to supplement mains water. The most common way to meet the additional water supply requirement is to install plumbed minimum-sized rainwater tanks.”

Is harvesting rainwater more costly than only using mains water? No! Once the tank is installed and your water use is supplemented by the harvested rainwater, your water bills should be lower. After all, rainwater is free!

Harvested rainwater is collected from various hard surfaces such as rooftops and/or other man made above ground hard surfaces. The water is stored in a tank. The below diagram (credit: treehugger.com) shows how rainwater harvesting works.

Ri-Industries manufactures underground concrete rainwater tanks. Concrete rainwater tanks offer a number of advantages:

  • The water stays cooler.
  • No algae develops.
  • The water has no after-taste.
  • They are vandal-proof and fire-proof.
  • Being underground means they are out of sight and don’t take up much of your valuable real estate.
  • Concrete is stronger and more durable.

Our rainwater tanks are built to stand the test of time. They’re made from high frequency vibrated reinforced concrete using the highest quality of materials. Steel mesh is cast into the rainwater tanks and lids, and all fittings are made from brass – to give additional peace of mind. We also have full engineering approval for below ground tanks. This means you can rest easy knowing that a Ri-Industries rainwater tank will serve you well, wherever it is installed. We can also custom make inlets and outlets to suit your specific requirements.

How to Create a Rainwater Harvesting System

by Ri Industries

Congratulations! You’ve done the research and have decided that collecting rainwater is a good decision for your household. Now you need to learn what steps need to be taken in order to begin collecting rainwater.

First,  you must decide which type of storage tank you will use. The experts at Ri-Industries recommend our concrete underground rainwater tanks which offer the following benefits:

  • The water stays cooler.
  • No algae develops.
  • The water has no after-taste.
  • They are vandal-proof and fire-proof.
  • Concrete is stronger and more durable.
  • Being underground means they are out of sight and don’t take up much of your valuable real estate.

Once you’ve decided which type of storage tank you will install, it’s time to think about how you will actually collect the water. House, garage and shed roofs are generally used as catchment areas. 

To keep the rainwater clean, it is important to attach leaf screens to gutters, prevent vegetation from overhanging the roof, and thoroughly clean the roof and gutters before installing. Avoid collecting rainwater from sections of the roof that contain lead flashing or asbestos sheeting, as well as from roofs painted with pre-1980 paint. 

Some extra steps should be taken when using the collected rainwater as drinking water. The Plumbing Code of Australia requires that a testable backflow prevention device is fitted on any mains water supply to the house and tested annually. First flush diverters are recommended for all drinking water systems and are beneficial for systems supplying other internal uses. For garden irrigation supply, their main benefit will be to reduce the need for desludging the tank. Since dust, debris, and bird droppings accumulate on the roof during dry spells, the first rain will wash them off the roof and into your rainwater tank. First flush diverters are designed to prevent the unwanted substances from entering the tank. 

Now that the rainwater has been collected and stored in the tank, you will need a system to bring the water into the house or out to the garden. You have a couple of options to use with the Ri-Industries concrete water tanks. 

A header tank is a great choice for use with an underground tank. It is placed at a higher level than the storage tank. A low-powered pump will transfer the water from the rainwater tank to the header tank, then the water is released using gravity.

A pressure pump is another option which will deliver water at, or near, mains pressure.  You will need to decide between a submersible or free-standing pump and will also need to install a pump controller. 

Collecting rainwater is a fantastic way to save money and resources. The experts at Ri-Industries can help you choose the system that is best for your home. Please call us at 08 8444 8100 with all your questions.
