|Contract works||Enhancement and upgrade of Perth's two main metropolitan wastewater treatment plants|
Thiess was part of a successful consortium that delivered an enhancement and upgrade of Perth's two main metropolitan wastewater treatment plants. The program of works was delivered under an alliance agreement with the Water Corporation and a design and construction consortium of Thiess, Black & Veatch, and Sinclair Knight Merz. The program of works involved the upgrade of Beenyup and Woodman Point wastewater treatment plants.
At the end of the program, the capacity of the Beenyup wastewater treatment plant was increased by at least 15 million liters a day. At the Woodman Point Wastewater Treatment Plant, the solids treatment capacity was also increased to align with the overall hydraulic capacity of the plant of 160 million liters a day.
