According to newly released data from Sydney Water, Mosman residents are among the highest water consumers. They use nearly 65,000 litres more than the average Sydney home.
Sydney’s Water Usage Reaches Record High
Sydney Water has reported a significant rise in water consumption across the city. Mosman, Hunters Hill, and Ku-ring-gai are among the top five water-consuming suburbs and Woollahra recorded the highest usage. Woollahra averaged 304,000 litres per household annually.
Between December 2024 and January 2025, Sydney Water supplied over 99 million litres of water across Sydney, the Blue Mountains, and the Illawarra. An increase of nearly 5% compared to the same period last year has been noticed.
Sydney Water’s Conservation Manager, Suhanti Thirunavukarasu, highlighted the importance of mindful water use during the hotter months when demand rises.
How Mosman Compares to Other Sydney Suburbs
New data reveals that Mosman households consume an average of 267,000 litres of water annually. In contrast, the water-conscious suburb of Kiama uses just 146,000 litres per household.
The top five water-consuming suburbs in Sydney include:
- Woollahra: 304,000 litres per household
- Hunters Hill: 277,000 litres per household
- Mosman: 267,000 litres per household
- Ku-ring-gai: 247,000 litres per household
- Strathfield: 245,000 litres per household
On the other hand, some of the most water-efficient suburbs include:
- Blacktown: 206,000 litres per household
- Parramatta: 205,000 litres per household
- Penrith: 205,000 litres per household
- Campbelltown: 202,000 litres per household

The Push for Water Conservation
Sydney Water has urged residents to be more mindful of their usage. Small habits like leaving hoses running or taking long showers contribute to rising demand.
The agency has planned a $30 billion investment over the next decade to upgrade and expand water and wastewater networks, catering to Sydney’s growing population and increasing water needs.
Future Implications and Next Steps
Sydney Water emphasises the importance of conservation efforts to prevent future shortages as water demand is climbing. Dam levels remain steady. Still, ongoing monitoring and sustainable practices are essential for long-term water security.
Residents are encouraged to adopt water-saving practices at home. Limiting shower times, fixing leaks, and using efficient irrigation systems are suggested to reduce unnecessary waste.
