Wastewater, Stormwater and Reuse

Overview of Program

SA Water's Wastewater research program is focused on meeting the challenges associated with the treatment and reuse of wastewater and stormwater by:

  • Managing Treatment: Improving the sustainability and performance of our wastewater treatment operations to reduce cost while maintaining regulatory compliance.
  • Managing Dispersals: Maximising beneficial reuse in a sustainable, safe and cost effective manner.
  • Managing Residual: Cost effective disposal of waste from wastewater treatment plants to reduce site contamination and odour issues, with emphasis on beneficial reuse.

Capabilities and expertise

  • Investigate novel biological nutrient removal (BNR) processes (e.g. granular sludge and anammox)
  • Nitrogen removal
  • Validation of wastewater treatment barriers for reuse (UV, membrane filtration)
  • Greenhouse gas monitoring
  • Quantitative Microbial Risk Assessment (QMRA)
  • Energy Benchmarking
  • Quantitative polymerase chain reaction (qPCR) of microbial populations in BNR systems
  • Troubleshoot filamentous bulking in activated sludge

Past and current projects
