Wynnum Sewage Treatment Plant

The Wynnum Sewage Treatment Plant was a separately negotiated scope increase to the original Brisbane Water Enviro Alliance (BWEA) project. The plant featured a 130 metre long monolithic oxidation ditch and segmental, post-tensioned circular clarifiers. Bonacci Infrastructure delivered the structural design package.

The project was delivered to Brisbane Water as a “Pure Alliance” contract and had a contract value of approximately $22 million.
