Five tips for water conservation
Five tips for water conservation
Sydney Desalination Plant (SDP) is Australia’s third-largest desalination facility, supplying up to 15% of Sydney’s drinking water. As the city’s only major rainfall-independent source, SDP plays a vital role in ensuring a reliable and safe drinking water supply for Sydney year-round.
Drinking water is one of our most precious resources and using it wisely is everyone’s responsibility. Small changes in our daily routines – like shorter showers, fixing leaks quickly, and choosing water-efficient appliances – can make a big difference. Together, we can conserve water and support a more sustainable future for Sydney.
How can everyone work to conserve water in Sydney?
- Avoid leaks:
- – Visible leaks should be a top priority. A leaking toilet can waste as much as 260 litres of water every day.
- – Concealed leaks are leaks hidden underground or in walls. If you can’t see a leak but your bill has increased for no reason, you may have a problem. Call a specialist plumber to address the problem.
- – Install water efficient appliances such as front-loading washing machines.
- In the kitchen and laundry, build water saving habits:
- – Fill a jug and keep water in the fridge so you don’t have to wait for tap water to run cold.
- – Wash vegetables in a plugged sink instead of under a running tap. Better yet, wash them in a bucket or bowl and water your plants with what you collect.
- – Wait for a full load of dirty dishes before turning on the dishwasher.
- – Put a plug in the sink to wash vegetables and dishes.
- – Wait for a full load of washing before turning on the washing machine.
- – Wear clothes and use towels more than once before they go into the washing basket.
- – Don’t hand wash items one at a time. Plug the tub and do them together and save all rinsing for last.
- In the bathroom, avoid running water for too long:
- – Install water saving shower heads and take shorter showers, if everyone in Sydney cut their shower time by 10 seconds, we’d save over 8 million litres of water a day.
- – When you replace your old toilet, get a dual flush. Half-flush toilets to save up to four buckets of water per day.
- – Use a plug to keep water in the sink for rinsing your razor or washing your face. Don’t keep the tap running.
- Be intentional about looking after your pipes:
- – Dispose of fatty liquids rather than down pouring them down the drain.
- – Have a bin in your bathroom to avoid binning items in your toilet like wet wipes, cotton products, dental floss, hair and tissues.
- This coming summer, be conscious about when you use water:
- – Keep water in the fridge to provide quick access to cold water without running the tap for ages.
- – Water your garden wisely in the early morning or evening to avoid water evaporation and water the roots of each plant, not the leaves
- – Install a rainwater tank. If a rainwater tank is properly installed and plumbed into your home, you could save up to 40% of your drinking water needs. Collect rainwater for gardening or cleaning to save water and use a rake rather than a hose to clean driveways and pathways.
- – If you think you need a garden watering system, choose one with plenty of water efficiency options to prevent overwatering. A sprinkler uses 900 litres every hour.

Frequently Asked Questions
- Is the Sydney Desalination Plant operating?While the Plant was originally designed to operate only in times of drought, it has remained operational since 2019 to help address several storage dam water quality issues arising from bushfires, flooding and significant maintenance tasks in Sydney Water’s supply network.
The Sydney Desalination Plant’s WICA Network Operator’s Licence enables the Plant to remain operational, recognising that the Plant has always been, and will continue to be, an essential component of Sydney’s water management and an integral part of our city’s water-resilient future. - How much water does the Plant produce?The Plant can provide up to 15 per cent of Sydney’s average drinking water needs without any reliance on rainfall.
It treats, filters and re-mineralises seawater to produce up to 91.25 gigalitres per annum of high-quality drinking water.
Under our WICA Network Operator’s Licence, the Plant will operate on a “flexible full-time basis”, producing between about 20 gigalitres to 91.25 gigalitres every year. - What does desalinated water taste like?Sydney Desalination Plant water is treated to taste the same as Sydney’s other drinking water.
Like dam water, water from the desalination plant is treated to meet Australian Drinking Water Guidelines, which makes it among the best in the world. - Who owns the Plant?Sydney Desalination Plant is jointly owned by the Ontario Teachers’ Pension Plan Board and the Utilities Trust of Australia, which is managed by Morrison. Find out more on our About Us page.
- Why is desalination important?The Sydney Desalination Plant is Sydney’s only major sources of non-rainfall dependent drinking water. It is one effective way of securing Sydney’s water supply against the effects of climate change and natural disasters and the increase in demand due to population growth, warmer weather and urban greening projects.
While the Plant was originally designed to respond to Australia’s severe millennium drought, recent experiences have demonstrated that drought is only one type of event that requires support from the Plant to ensure clean and safe drinking water for Greater Sydney.
The Plant has been a reliable drinking water supply during floods and bushfires, which caused water quality challenges from time to time in Sydney’s storage dams. - Where does the water go?The Plant can supply water to homes and businesses south of Sydney Harbour and as far west as Bankstown, as part of all their water supply.
Sydney Water uses a variety of water sources to supply customer needs. Where your water comes from depends on demand and where in Sydney you live.
If you live in the blue-shaded area on this map, you may receive water from the dams, the Sydney Desalination Plant or a combination of both. The Plant's water proportion will change throughout the day due to variations in supply and demand.
Everyone will benefit from desalination because it allows more water to be left in the dams, which means a more secure water supply for Sydney. - How much energy does the Plant use?The Sydney Desalination Plant requires roughly 38 megawatts at full production and is 100 per cent powered by renewable energy.
The average energy needed to provide drinking water to one household is about the same as the energy used to run a household fridge. - What’s the impact on the environment?Sydney Desalination Plant places a high priority on minimising any environmental impacts – both on land and in the water.
To support this, the Plant has put in place a world first stringent six-year marine environment monitoring program. The marine environment was monitored for three years before construction and three years after the Plant became operational. It demonstrated that the Plant has minimal effect on the marine environment.
On land, a third of the Plant site at Kurnell has been maintained as a conservation area. This area is protected, and native species of flora and fauna are regularly monitored. This includes a program to survey the numbers of grey-headed flying foxes and green and golden bell frogs in the area.
