Westfield Westlakes needed a wastewater treatment system to support significant growth at its busy food court. The existing series of grease arresters were no longer sufficient to meet SA Water’s guidelines.
Aerofloat installed its patented AeroCIRC M600 DAF to ensure Westfield Shopping Centre met existing demands, whilst also allowing for future business growth at the site. Aerofloat’s custom-designed solution fit the limited space available at the site.
Aerofloat ensured the system had the capacity to treat peak wastewater flow rates well above the current levels, allowing for additional growth at the site.
The shopping precinct at Westfields, Westlakes in South Australia (SA), required an innovative wastewater design to meet increased flow rates. The wastewater from the stores in the food court had grown. This meant that the series of grease arrestors in place to treat the wastewater prior to sewer discharge was no longer sufficient to meet SA Water’s guidelines.
Aerofloat was able to customise a system to fit the tight space available at the site.

Strong business and clientele growth in recent years meant that the Westfield shopping precinct located in Westlakes, South Australia, needed an updated wastewater treatment system to support its busy food court. The popular shopping hub housed numerous cafés and restaurants and significant growth in people visiting the court each week meant higher wastewater flows at the site.
The wastewater from the stores in the food court had grown. This meant that the series of grease arrestors in place to treat the wastewater prior to sewer discharge was no longer sufficient to meet SA Water’s guidelines.
Aerofloat was contracted by The Scentre Group, to customise a treatment system to manage wastewater generated from the existing restaurants, cafés and fast food outlets. The system needed to be able to adapt to additional planned growth at the site, given extensions to the fresh food area were expected in the future.
Aerofloat installed its patented AeroCIRC M600 DAF to ensure Westfield Shopping Centre met existing demands, whilst allowing for future business growth at the site.
Aerofloat’s GM of Operations, Michael Anderson said Aerofloat was able to customise a system to fit the tight space available at the site.
“The footprint was quite small, but we had a lot of height to work with, so we custom-built stainless steel tanks that were quite tall.”
Maintaining the system was also considered in the design.
“We created a platform that was suspended off the top of one of the tanks, allowing servicing access to the system from the roof,” said Anderson.
Wastewater generated at the site was typically from on-site cooking facilities and general dish washing. The AeroCIRC M600 DAF system treated the high concentration of suspended solids (SS), and fats, oils and grease (FOG) in the food outlet wastewater. Aerofloat’s unique design ensured minimal DAF maintenance for operators.
Aerofloat currently services and operates the system on behalf of Westlakes ensuring all discharge specifications from SA water are being met.
Aerofloat’s design at the Westfield Shopping Centre handled the wastewater generated from the existing restaurant and fast food outlets. The system had the capacity to treat peak wastewater flow rates of up to 36 m3 per hour, well above the current flow rates. This ensured that additional wastewater generated from the expected extensions to the fresh food area in the future would be managed.
