Washing machines are typically the biggest water users in the laundry. While they require a lot of water to operate, you can make a few simple changes to your weekly washing routine to reduce the water you use in your laundry.

Load up the washing machine

Reducing your washing by just one load a week will save you up to 120L. It’s also a good idea to get into the habit of only running your washing machine when you have a full load.

Where possible, wash in cold water as this will also save energy, and use the eco or energy saver mode (if your machine has one) when you have several full loads on the go. This will also limit the amount of detergent required.

Need a new washing machine?

Older models can use as much as twice the water of newer models. If you’re in the market for a new washing machine or you want to upgrade, look out for washing machines with a WELS star rating of 4 or more. The more stars the appliance has, the more efficient it will be and the less water it will use.

To minimise your total running costs, you should select a model within your budget that is high in both water and energy efficiency.

Choose water efficient fittings

Go for WELS 4 star rated taps or install flow-controlled aerators. You can contact a Waterwise Plumber to help with installation.

Think you have a leak?

Leaking taps waste up to 10,000L per year! You can use our simple leak detection tool to check whether your laundry taps are leaking.

Fixing a dripping tap is usually as simple as replacing a washer.

Consider installing a greywater system

If you’re building a new home, you could save even more water and reduce your water bill with a greywater system.

What is greywater?

Greywater is the wastewater from washing machines, showers, baths, wash basins, spa baths, laundry tubs and kitchens. Greywater from your laundry (or bathroom shower and sink) can be used to water your garden, provided you meet certain requirements.

Designing and installing a greywater system

You should use a qualified greywater installer to design and install your greywater system, as there are a number of things that may determine whether greywater is suitable for your property. They’ll also ensure the system performs efficiently and provides an adequate amount of water for your garden.

Can I install a greywater system to my existing home?

It’s possible to retrofit a greywater system, given it can work with your current plumbing and garden layout. Speak to a greywater professional for expert advice on an appropriate system design that’ll work for your property.
