We all know water is our most precious resource – let’s do our best to conserve water.
Adhere to the current water restrictions put in place and enforced by Sydney Water.
- Reduce shower time by using a timer and install a water efficient ‘AAA’ showerhead
- Only run a dishwasher when it is full.
- Ensure the washing machine load adjustment is correct, or wait until you have a full load.
- Install dual flush cisterns on toilets.
- Don’t leave the tap running while brushing teeth or shaving.
- Install flow controlled aerator adapters on taps. These can reduce the water flow from between 15L per minute to either six, nine or 12L per minute.
- Check for plumbing leaks. Take a water meter reading overnight. If there is a change in your meter reading and no-one has used water overnight you may have a leaking pipe, tap or toilet cistern.
- To check for toilet leaks put food colouring in the cistern. If the colouring appears in the bowl without the toilet being flushed, the cistern needs repairing.
Go one step further!
- Use a sink strainer.
- Use phosphate-free, eco-friendly detergents and cleaning products.
- Have a garden appropriate for the climate you live in. Use local native plants instead of exotic plants. Native plants require less water, fertilisers and pesticide. Select a native that requires little water from Sydney Water’s easy to use plant selector database .
- Install a drip or mist system that will apply appropriate amounts of water directly to your plants. Water your garden in the morning or evening to avoid water loss through evaporation.
- Sweep up garden vegetation and put them on the garden as mulch. Mulch reduces evaporation and retains soil moisture.

Greywater is household wastewater that has not come into contact with toilet waste. It comes from the kitchen sink, dishwasher, bath, shower, bathroom hand wash basin, clothes washing machine, and laundry trough. Water from household air conditioners is not greywater, and there is no objection to its reuse on gardens.
Using greywater appropriately can save tens of thousands of litres of drinking water each year, reducing water bills and keeping gardens healthy during times of poor rainfall.
How can I use greywater?
Capture in a bucket and use on gardens and lawns. For example capture the cold water running from the shower as you wait for the hot water to run.
Diversion devices to divert greywater from the house for use on gardens and lawns using sub-surface irrigation. Council approval to install is not required if certain requirements are met. Council approval to operate diversion devices is not required. A licensed plumber is needed to install devices.
Treatment systems are needed to be able to store and reuse greywater inside the home for uses such as toilet flushing and in a washing machine in addition to on gardens or lawns. Council approval is required to install and operate treatment systems. A plumber is needed to install treatment systems. All treatment systems are required to accredited by NSW Health.
More information about requirements, appropriate systems and how to find a licensed plumber can be found at the NSW Office of Water - Greywater .
