Up your sustainability game by recycling greywater for your garden.


1Gather your tools and materials

Below you'll find all the tools and materials you'll need to complete this project.

2Identify greywater around your home

The first thing you need to do is identify the water you can use from around your home. Avoid using water from dishwashers and kitchen sinks. This type of water is known as dark greywater, because it has a higher concentration of chemicals, fats and other organic matter that isn't good for your garden. Water from toilets is called blackwater and isn't safe to use in your garden.

3Collect your greywater

There are some simple ways to collect the greywater from around your home.

If you have a shower over a bath, then simply insert the plug into the bath before you shower. At the end of the shower you'll be able to use a bucket to transfer the water outside. If you don't have a bath under your shower, grab a large tub that can be placed in the bottom of the shower to collect the excess water.

Redirecting the used water from your washing machine is a great way to collect greywater. Simply get the water outlet hose that is usually directed towards a drain and place it in a large bucket. Remember to keep an eye on the bucket as your washing machine goes through its cycle to make sure it doesn't overflow.

Another great way to collect your greywater is from your laundry sink or bathroom basins. Once you have finished using the water in your sink, use a bucket to scoop out the water to take outside.

4Treat your water

Once you have collected greywater from around your home, you need to treat the water prior to distributing it around your garden. We are using Yates Greywater Fertiliser, which has multiple benefits. It helps neutralise the effect of alkaline soaps and detergents on soil pH, contains a bactericide to kill unwanted microbes in greywater and it has added nitrogen and potassium to create a balanced fertiliser to feed plants and lawns and encourage healthy growth.

To treat the water, add 20–40mL of Yates Greywater Fertiliser for every 10L of greywater, and then apply around non-edible plants every 2 to 4 weeks.

5Try it on your lawn

If you have a lot of green foliage in your garden or plan to use greywater on your lawns, it also contains chelated iron to promote deep green foliage and lawns.

Pro tip: it's really important that you don't store greywater on your property. So make sure you use it as soon as you collect it!

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
