Graymade successfully delivered the civil construction works for Glenfield STP Biosolids Odour Control Unit (OCU) project at Macquarie Fields. The works included the construction of reinforced concrete equipment slabs, vent stack foundations, duct bridge footings, drainage infrastructure, and associated civil works required to support the installation of the new odour control system.

Delivered within an operational wastewater facility, the project required careful planning, coordination, and quality execution to meet stringent construction and safety standards. Graymade worked closely with project stakeholders to provide the essential civil infrastructure that enables the effective operation of the odour control facility, supporting improved environmental outcomes and long-term operational reliability.
