Description

Greater Western Water’s Altona Treatment Plant brings together engineering, science, sustainability and art in one unique place.

Operating as essential environmental infrastructure, the facility treats millions of litres of wastewater each day using advanced technology and carefully managed biological processes. Through this work, wastewater is transformed into recycled water suitable for irrigating nearby parks and green spaces, and for release into local waterways.

Embedded within the operational treatment plant is A Forest for Australia, created in 1998 by internationally recognised environmental artist Agnes Denes. Spanning eight acres, the living artwork features 3,700 trees planted in five circular spirals, a powerful statement about regeneration and humanity’s relationship with the environment.

Together, the treatment plant and the forest create a uniquely layered landscape. Visitors encounter the practical systems that sustain a modern city alongside contemplative artwork that reflects on ecology, resilience and our shared environmental future.

What's On

Enjoy rare behind-the-scenes access of the Altona Treatment Plant with a guided tour, and learn about the processes of treating wastewater daily and the importance of producing and supplying recycled water for a sustainable future.

The program also includes a visit to A Forest for Australia, exploring its design, climate challenges and ongoing renewal. This is a unique opportunity to explore the artwork, and learn about its challenges and rejuvenation.
