McConnell Dowell & HEB Joint Venture was awarded the project due to our ability to deliver an optimal solution for the customer at the right price. The scope of work involved the construction of two new reactors, two clarifiers, a blower building, ethanol dosing facility, several pump stations, splitter boxes, secondary effluent pipeline, sludge storage tanks and interconnecting pipework. This provided additional secondary wastewater treatment capacity for approximately 250,000 people. The project also included the construction of a new road linking Ascot Road and Puketutu Island, and an embankment to the south of the new facility. The embankment and associated landscaping enhanced the appearance of the plant and minimised the impact of the expansion on residents. 3 Army Bay Outfall, Auckland McConnell Dowell has commenced working on the Army Bay Outfall for Watercare in Auckland.
