A number of Australian Stainless Steel Development Association (ASSDA) members have been sub-contracted by Thiess for the construction of the Bundamba Advanced Water Treatment Plant (BAWTP).
Water preservation is crucial in Australia today. As populations rise and dam levels fall, the importance of treating and reusing water has become a high priority.
The construction of BAWTP, west of Brisbane, is aimed at alleviating pressure on South East Queensland’s existing dams and waterways by providing an alternate water supply for end users in the region.
The project has had great emphasis on the Australian stainless steel industry as infrastructure requirements point to the material for its strength, corrosion resistance and application performance.
The BAWTP is a joint venture between Thiess and Black & Veatch, who are responsible for the engineering, design, procurement and construction. ASSDA Accredited Fabricator D&R Stainless, Perfab Engineering and Stainless Pipe and Fittings Australia have had a major role in the project.
Many of the piping materials for the first two stages of the project were supplied to Thiess by Stainless Pipe and Fittings. Materials were in excess of 350 tonnes and included pipe, pipe fittings and flanges in grade 316L with sizes ranging from 25-600nb.
Once delivered, D&R Stainless cut and bevelled the pipe. It was then welded and passivated internally and externally before undergoing hydro testing.
Perfab Engineering was also sub-contracted for the manufacture of the Reverse Osmosis (RO) skids at its workshops in Newcastle.
The work carried out by Perfab Engineering included fabrication and surface treatment of the carbon steel skid frames, fabrication of the stainless steel pipework, full mechanical installation of the valves, instrumentation and RO pressure vessels, pneumatic fitout, electric fitout and testing.
At present, the BAWTP 1A is in full operation and delivering water to the Swanbank Power Station. Thiess Black and Veatch Director, Gus Atmeh, said that the BAWTP 1A project was delivered ahead of schedule and this was due to the support of the project by high quality stainless steel fabrication shops from across Australia and particularly from South East Queensland, who provided stainless steel components for state of the art process equipment and piping.
