SUEZ awarded for its operator & service provider excellence
In April at the 2017 National Infrastructure Awards, SUEZ was awarded the Operator and Service Provider Excellence Award for its work with Water Corporation at the Perth Seawater Desalination Plant (PSDP).
The awards, convened by Infrastructure Partnerships Australia, celebrate achievements in the delivery of significant infrastructure projects across Australia and New Zealand.
SUEZ was recognised for the quality of ongoing delivery of service and management of operations of the facilities for Water Corporation.
CEO – Water & Treatment Solutions David Lamy received the award with Darren Chapman, Plant & Alliance Manager.
“Our job has been simple: to provide a safe, reliable and cost-effective water service for our client and the residents of Perth,” Lamy said.
“We have been proudly doing that for more than a decade, and this award recognises the team’s efforts in striving for operational excellence every single day.
“The plant plays a vital role in securing water supply for Water Corporation’s Integrated Water Supply Scheme, which supplies the metropolitan area, parts of the south west, and the Goldfields and Agricultural region.”
The award judges noted that the PSDP is one of the most cost-effective desalination plants in Australia and acknowledged the team’s enviable safety record, which surpassed 4000 lost time injury free days this year.
“We look forward to continuing our work with Water Corporation to continue to provide a reliable and cost-effective water supply that households, businesses and farming areas can rely on well into the future,” Lamy added.
Perth seawater desalination plant provides many benefits
At the start of the 21st century there was growing concern in Western Australia over the declining natural supplies of water in the area. This concern was well founded: the winter of 2001 had seen the poorest inflow of water to the reservoirs serving the Perth metropolitan area for 86 years. In 2002 it was clear that the region was suffering the worst two-year drought on record, and by 2005 stream flows had dropped nearly 30% over the preceding eight years.
In April 2005 the Premier of Western Australia announced the award of the PSDP to a joint venture of SUEZ and Multiplex Construction. Construction of the plant began almost immediately. The plant delivered its first water order within 18 months – ahead of schedule.
At the time it was the largest seawater reverse osmosis desalination plant in Australia, and to this day continues to provide 45 billion litres of safe drinking water per year – around 18% of Perth's total water supply – making it a critical piece of infrastructure in the fight against ongoing issues with drought.
SECURE AND RELIABLE:
The PSDP has provided a secure and reliable water supply since it became operational in 2007. Farms, businesses and households throughout the Perth area can rely on a constant source of potable water, regardless of climactic conditions.
SMART AND COST-EFFICIENT:
The PSDP is one of the most cost-effective desalination plants in Australia. The plant consistently operates on budget, providing budget certainty to the Water Corporation and the State Government.
Innovative technologies have also been utilised to achieve power savings. The pressurisation of the water prior to the reverse osmosis process accounts for up to 50% of total operational costs. The pressure exchangers, however, recover residual pressure from the concentrated brine discharge and have reduced power requirements by up to 20%.
Since the beginning, ensuring optimal environmental outcomes has been a key requirement of the project. The PSDP seawater inlet and brine discharge are located in Cockburn Sound, a sensitive marine ecosystem. An innovative system was designed to disperse brine (a fluid waste with high concentrations of salts and dissolve minerals) using a diffuser-based outfall. By dispersing the brine at regular intervals along the final 200 metres of the diffuser, the environmental impact was greatly reduced, while extensive monitoring of total dissolved solids, temperature, dissolved oxygen and sediment ensures the marine habitat and fauna are protected. This monitoring has demonstrated marine life continues to flourish near the diffusers and throughout Cockburn Sound.
