Treatment III: Night + Day is a unique event featuring 9 newly commissioned artworks to be experienced across the remarkable Western Treatment Plant in Werribee.

Celebrating a day in the life of the plant and responding to the extraordinary landscape, technologies and community surrounding Melbourne’s oldest and largest waste treatment facility, TIII: Night + Day will bring the site alive through live music, sculpture, film and performance works from sunset on Friday 21 April and sunrise on Saturday 22 April.

Terrain & Navigation

The Western Treatment Plant is primarily an outdoor site comprised of various terrain, including concrete, uneven dirt/grass, large and small compacted gravel. Manual wheelchair users will find it difficult to navigate independently due to the nature of this terrain. Motorised wheelchair users may also find it difficult to access certain works situated on large gravel and grass. All wheelchair users are encouraged to email publicartcommission@gmail.com prior to booking, so that we can discuss access to the event in further detail with you. If you leave us a contact number and your availability, we can call you back at a time convenient to you.

In terms of distance to travel by foot onsite, patrons are advised that there are parts of TIII: Night + Day that involve walking longer distances (over 100m).

Please email us using the address above if you have any queries about site navigation. A Site Map will be shared on this webpage in the coming week.
