Our Coombabah and Stapylton Program Alliance (CaSPA) recently fitted several concrete roofs as part of the $65 million Coombabah Wastewater Treatment Plant’s stage five upgrade.

One of the roofs, a 88-tonne lid, was positioned on a 23 x 16 metre digester wall, signifying a major milestone for the project.

Due for completion in mid-January 2013, the upgrade is an important Gold Coast infrastructure project to increase the plant’s capacity from 75 million to 91 million litres per day.
