Water Tanks for Laundry

Pioneer Water Tanks - Using Rainwater in your Laundry

Free Yourself from Mains Water

With water restrictions increasing in Western Australia, along with the cost of living which includes the residential water bill, many people are looking for ways to avoid using as much town water as they might have in years gone by.

One way people are looking to do this is by installing rainwater tanks. While many people in rural areas have no choice but to use rainwater for their laundry, people in areas who do have access to mains water are beginning to turn to rainwater harvesting to supplement their water usage.

A rainwater tank is an effective way to increase your water supply without increasing your water bill, and rainwater tanks for the home are now found in more than a quarter of Australian houses, for a range of purposes including drinking water, water for gardens, and rainwater supply for the laundry,  toilet and bathroom.

Pioneer Water tanks has been providing rainwater tanks to Western Australian homes for more than 30 years, and with an antimicrobial water tank liner to keep your water fresh paired with a 20 year warranty, you can rest assured your harvested rainwater is in safe hands.


Pioneer Water Tanks have provided a service for Western Australia since 1988. Our high quality Australian-made water tanks will provide the long-term water security you’re looking for.

Water Tanks for the Laundry

Is rainwater safe to use in the laundry?

For many people who have been using mains water or scheme water their whole lives, one of the first things they may wonder when switching to rainwater is if it is safe to use in their washing machine.

The good news is, not only is rainwater safe to use in washing machines, it might just be the best water source for washing clothes with.

Other water sources – such as bore water and tap water – are high in minerals including calcium, fluoride and chlorine, making them hard water sources which may impart these minerals on your clothing. 

Rainwater on the other hand, is what is known as soft water, and fluctuates between 5.6 and below on the pH scale. This means that not only will you require less laundry detergent and less rinse cycles, but it will also absorb many of these compounds from your clothing in the wash cycle.

Rainwater tanks and greywater systems

For those looking to get an extra water saving kick out of their water tank, there is also the option of installing a grey water system to support your rainwater storage.

Water from the shower and washing machine can often be reused in other parts of the home, including the toilet and parts of the garden that aren’t being used to grow herbs, fruit or vegetables.

The installation of a greywater tank is simple, and includes diverting the shower drain and laundry sink/washing machine overflow into a secondary storage tank to be used for reticulation and irrigation in the garden.

For those who want to go the extra step, there are also filters which can be fitted to your greywater system, making it safer for reuse on plants that might require fresh and clean water to be washed properly, and to prevent the build-up of calcium or other chemicals in the toilet cistern.

Why Choose a Pioneer Water Tank for your Laundry Water Storage

The major factor that will determine the best rainwater tank for your laundry water storage and for your home, is how much space you have available. If you are looking for a medium to large steel water tank, and  have enough space for a tank size in the tens of thousands of litres Pioneer Water Tanks is surely your best bet.

For those with less room however, who are just looking for a rainwater tank for the laundry or garden seeking to bring down the price of their annual water bill, then you may be better suited to a smaller water storage system, such as a slimline water tank, or other small poly water tanks or galvanised steel water tanks. Many of these slimline tanks or other plastic water tanks are designed to fit down the side of suburban homes, making the most of minimal space.

Frequently Asked Questions

Can rainwater be used for laundry?

Rainwater lacks the additives and minerals that bore water and tap water contain. Bore water or ground water is often high in magnesium, manganese, iron and calcium, while tap water typically has added chlorine and fluoride to keep the water safe for human consumption. Rainwater, on the other hand, is soft water, meaning you can use less detergent and soap in the laundry while also stripping clothes of the minerals found in other water sources.

Is rain water clean?

The cleanliness of your rainwater will be entirely dependant on where you are harvesting it from – both in terms of your location, and your rainwater catchment. If you are living in an urban area, or an area near an industrial site or main road, your water may be suffering from pollution. The same goes if you aren’t keeping your roof or gutters clean. In most of Australia, rainwater has been deemed safe to drink, and certainly safe to use in showers and washing machines.

Is rain water hard or soft?

Rainwater, as opposed to town water, typically has a pH of 5.6 or below making it a soft water source. This means that your tank water is more likely to absorb trace elements and minerals from your clothes than it is to impart them on there. This is also true for watering gardens and lawns, with rainwater being higher in nitrogen, and lower overall in trace elements, allowing it to absorb carbon dioxide and other elements on the plants and in the soil.

Can you drink water from a rain tank?

In many parts of the world, high levels of pollution make rainwater high in contaminants, and cover the roofs used for rainwater harvesting in a layer of sediment and chemicals. However, Australia doesn’t experience these levels of pollutants – particularly in rural areas – and the rainwater in Western Australia is typically deemed safe to drink according to the Department of Health’s Healthy WA website‘s drinking water guidelines.

Provided you are not located near heavy road traffic or any industrial or agricultural site that may be releasing pollutants, it then comes down to having the right rainwater storage device for your needs, and ensuring that your rainwater harvesting systems are kept clean and maintained from roof to tap.

Do rainwater tanks need a pump?

Typically rainwater tanks to not require a pump, as the water contained in the tank is heavy enough to create adequate water pressure to push the stored water to any taps or pipes within the home. When tanks are located too far from the house, or are perhaps close to empty and don’t have sufficient weight to create adequate water pressure, a pump may be required.
