Sydney Olympic Park is home to Australia’s most successful integrated water recycling system saving over 900 million litres of water annually. Harvested water is used across the precinct for landscape irrigation, toilet flushing, washing machines and water features or fountains.
The Authority requires all new development to connect to the Authority’s recycled water system to reduce potable water consumption by all users.
During 2017-18, 919,821 kilolitres of recycled water (the equivalent of 368 Olympic swimming pools) was produced for use in Sydney Olympic Park and the adjacent suburb of Newington.

- If you have don’t have a dual flush toilet, employ a plumber to install a dual flush or adjust the flush volume.
- Try adjusting the flush volume yourself by inserting a water displacement device into the cistern. You can purchase the device or use a plastic bottle filled with water; the size of the device or bottle of water will depend on how much room is available in your cistern. To place the device in, remove toilet cistern lid and flush the toilet, once most of the water is gone, place your device in. When inserting a water displacement device, make sure that its placement doesn’t obstruct the flushing mechanism.

What can you do to save water on the balcony garden?
- Minimise outdoor water use in your garden balcony by selecting plants that are appropriate for local growing conditions.
- Only water plants at night, this way less water is lost via evaporation in the sunny hours of the day.
- To save on water when watering plant pots you could also try digging in a small ‘olla’ (unglazed terracotta vessel). Ollas can work as a type of drip irrigation for your pot plants. You install ‘ollas’ by digging them into the soil and burying them up to the narrow neck. When you fill the opening of the ‘olla’ exposed at the surface of the soil, the water slowly seeps through the unglazed terracotta and into the soil below. Make sure to cover the top opening of you ‘ollas’ when not filling with water, to eliminate evaporation. You can purchase your own small ‘olla’ or even try making your own ‘olla’ at a local pottery class. Lean more about ‘olla’ design and see how you can DIY.
- Mulching is a great way to maximise the use of water put into your garden pots, as mulching helps to keep the moisture in soil and prevent evaporation. Learn about different types of mulch that can be utilised in your garden pots.
