Current and recent projects

Mackay Water Recycling Project, Queensland (joint venture with John Holland)
For Mackay Reional Council
Queensland's largest regional recycling project

Our role: Design, management, construction, commissioning and operations of the water recycling facilities for Mackay City Council.

Outcome: Tenix Alliance assisted Mackay City Council implement the largest regional water recycling project in Queensland. The project will enable water conservation through the irrigation of high quality effluent to 3200 hectares of sugar cane plantation. It has also resulted in reduced levels of odours and eliminating discharge to the sensitive Great Barrier Reef Marine Park environment.

 

BMP Alliance (2004 - 2009), Queensland
For Gold Coast City Council

Our role: The Beenleigh Merrimac Pimpama (BMP) Alliance is a $220 million program expanding the wastewater network on the rapidly developing Gold Coast. BMP Alliance has constructed 53km of wastewater pipes, decommissioned 34 pump stations, upgraded 42 pump stations, added overflow storage to six pump stations and built eight new pump stations.

Outcome: As infrastructure has been progressively delivered, Gold Coast Water has begun to experience many benefits including fewer wastewater overflows, reduced network operational costs, lower energy use and the elimination of operating noise and odours in residential areas.

 

Bega Valley Sewerage Program (Construction 2003 - 2008), NSW

For Bega Valley Shire Council, NSW

Our role: Design, construct, commission, operate and maintain five existing sewage treatment plants and the construction of Greenfield pressure sewerage systems, a including four Membrane Reactor (MBR) treatment plants and an effluent reuse systems.

Outcome: On the Bega Valley Sewerage Program, MBR treatment plants and LPS (Low Pressure Sewerage) systems were combined to provide a world-first solution. Tenix Alliance's innovative approach utilised recently available technology, involved the client at every stage of the program and rolled out community management and environmental approvals within the scope of works.

 

Brushy Creek Wastewater Treatment Plant (2007), Victoria

For Yarra Valley Water, VIC

Our role: Design, build and commission a Class A Recycled water treatment plant using Chloramination, UF filtration, UV disinfection, and Chlorination within tight timeframes.

Outcome: A technically complex Class A Recycled Water Plant (concept, design, approvals, procurement and commissioning) delivered for the client in just 16 weeks.

 

Industrial Wastewater Treatment Plant, Western Australia

For ABB Grain, WA

Our role: Tenix Alliance was involved in the design and construction of a wastewater treatment plant for Joe White Maltings' Perth facility. Tenix Alliance adopted a combination of Membrane Bioreactor and Reverse Osmosis technology for this plant to provide a treated water stream of a quality "better than Perth drinking water".

Outcome: Treating an average 1.4ML of wastewater daily, the Joe White Maltings system is now one of the nation's largest industrial combinations of membrane bioreactor (MBR) and reverse osmosis (RO) technologies providing security of supply for Joe White at its Perth facility, which churns out 40 per cent of the company's annual production of 500,000 tonnes of malt product. Tenix Alliance is now constructing a similar plant at Joe White Maltings' Ballarat plant in Victoria.
