Altona Treatment Plant opening its doors and land art for Open House Melbourne

Greater Western Water (GWW) is offering the public a rare opportunity to visit its Altona Treatment Plant, which includes an internationally recognised land art sculpture. 

Join the GWW team on 26-27 July for a guided walking tour of the Altona Treatment Plant, featuring world-renowned land art, A Forest for Australia, by acclaimed Hungarian American environmental land artist Agnes Denes.

GWW’s General Manager for Service Delivery Jodie Hallam said the organisation was looking forward to sharing both art and science with visitors for a second year. This follows a successful 2024 Open House Melbourne program when visitors rated the event as the second highest overall.

“It’s a great opportunity for the community to learn about the water treatment process, from what happens when you flush the toilet to how we’re keeping parks, gardens and farms green all year round with fit-for-purpose recycled water.

“We’re very lucky to have a beautiful piece of land art by Agnes Denes on the property, and we’re thrilled to once again open our doors to share this with the public.” said Ms Hallam.

Spanning 8 hectares, the piece features 3,700 trees of various species arranged in five circular spirals. Dene’s design was inspired by the energy and flow of water within the site’s tanks.

On a tour of the Treatment Plant, visitors will discover the fascinating water treatment process, where engineers collaborate with friendly bacteria to sustainably process millions of litres of wastewater daily, providing billions of litres of recycled water for industry and green spaces every year.

Tickets are now sold out, but you can still join the waitlist for this rare chance to explore both the treatment plant and the unique living artwork by renowned artist Agnes Denes.

Open House Melbourne is an independent, not-for-profit organisation that fosters public appreciation for architecture and engages the community in conversations about the future of our cities.
