Sustainable living isn’t just a goal in Cooranbong, NSW, it’s a daily reality. Nestled in the scenic City of Lake Macquarie, around 115 kilometres north of Sydney at the foothills of the Watagan Mountains, Cooranbong is redefining what it means to be a thriving, future-ready Australian community. By placing local water recycling at the heart of its infrastructure, Altogether’s innovative approach has unified smart water management, on-site treatment, and community engagement, ensuring sustainability and wellbeing grow hand in hand. As more urban developments across Australia seek resilient ways to ‘future‑proof’ communities, Cooranbong stands out as a benchmark for sustainable design and lasting environmental impact.
In Cooranbong, water management sets a new standard. The Cooranbong Local Water Centre powers impressive water savings and resilience. Here’s how:
Recycled Water Everyday: Recycled water is used for toilet flushing, garden irrigation, car washing, and even washing machines, reducing reliance on precious drinking water.
Data-Backed Impact: in 2025 we supplied 58.4 megalitres of recycled water to nearly 800 connected properties in Cooranbong, which equates to the saving of over 12 million toilet flushes worth of potable water.
Modern Technology: Advanced treatment (membrane bioreactor, UV disinfection, and chlorination) ensures the water is clean and safe, meeting all relevant health and environmental regulations for approved non‑drinking uses.
Affordable Sustainability: The recycled water pricing model is designed to be transparent and to provide residents with a stable, clearly structured tariff for non‑potable water use, helping support long‑term affordability.
Yes. The system meets all health and safety regulations and is regularly audited for quality, using advanced filtration and disinfection, in line with Cooranbong’s licences and approval conditions.
Cooranbong is designed to nurture a connected, thriving community, a place where sustainability goes beyond infrastructure and becomes a way of life:
Lush Public Spaces: Thanks to sustainable irrigation and water recycling, parks and shared gardens remain vibrant year-round, supporting outdoor recreation even during periods of regional water stress.
Smart Dwellings: Homes are equipped with technology to remotely monitor the health of the water system and proactively identify issues, helping ensure reliable service and early detection of leaks or interruptions.
Social Wellbeing: Outdoor events, local initiatives, and open communications foster a genuine neighbourly spirit, with sustainability messages and water-wise behaviours embedded in community life.
Cooranbong proves that a thriving, sustainable community can be built by integrating local water recycling, demand reduction, and community engagement. Its approach is replicable wherever there’s a will to innovate.
Residents enjoy more efficient water use, greater resilience to drought or water restrictions, and the satisfaction of supporting a cleaner environment. Community features, like lush parks and shared gardens, are practical, tangible bonuses made possible by reliable recycled water.
Recycled water in Cooranbong can be used for toilet flushing, cold water supply to washing machines, irrigation, car washing, ornamental water features, dust suppression during construction, and street cleaning. This wide range of uses allows households and community spaces to reduce potable water consumption and environmental impact significantly.
Cooranbong is now recognised as a flagship case study for our approach to sustainable living. As climate, water pressures rise across Australia, the lessons learned here are shaping new developments nationwide. Cooranbong’s model shows:
Sustainable living can be affordable and accessible when local water solutions are thoughtfully integrated from day one.
Smart systems and participation drive the best results.
People thrive where the place supports them, and the planet.
The Cooranbong development also stands as a showcase for responsible, future-focused urban planning. Altogether collaborates closely with developers and local government to design and manage local water infrastructure that not only meets current community needs but is also scalable for future residents and technological advances. By integrating water recycling centres into the heart of new communities, Altogether ensures fast land release, community resilience during environmental crises such as droughts and floods, and a high level of operational safety and regulation compliance. Industry leaders have praised Cooranbong for demonstrating how investment in local sustainable utilities leads to enduring comfort, lower resource wastage, and improved prosperity for all residents, solidifying its place as a blueprint for sustainable living in Australia.
Cooranbong demonstrates every day how sustainability is best delivered: through practical systems, community focus, and bold leadership. Residents don’t just live here, they belong here, knowing their home is part of a sustainable legacy. That’s the power of Altogether’s vision, brought to life through water.
