How to use a grey water system at home

Grey water has become a popular recycling alternative in the current environment. If you’re planning to install a grey water system, read our checklist on water treatment.

1. Grey water tanks

You can use any kind of water tank to store grey water: in-ground, bladder or poly tanks are all fine. However, bear in mind that you'll need two tanks - one to store the incoming grey water and one for the treated water.

2. How to treat grey water

It's illegal to store grey water for more than 24 hours, so if you want to store it for use in the home, it has to be treated. Grey water systems put the water through a process of aeration, filtration and 'polishing' to get it to Class A standard, which is required for indoor home usage.

3. Grey water usage

Once the treatment process has taken place, you can use the grey water for things such as clothes washing and toilet flushing.

4. Council regulations

Council approval is required to install a grey water system in a domestic setting. Some grey water recycling companies may do the application for you. There are often council fees involved, which can be anything up to $500. The rules differ in each state and council, so do some research into the grey water regulations for your particular area.

5. Installing a grey water system in an old home

Installing a grey water treatment system in an existing home is likely to cost you more because the pipe work will need to be diverted.
