Aeration Benchmarking Phase 2

Background

Aerators at Waste Water Treatment Plants (WWTPs) are a significant source of energy consumption by water corporations. An aeration efficiency benchmarking trial was carried out across 17 Victorian and interstate Waste Water Treatment Plants in 2016 and 2017 to determine energy benchmarks for WWTPs in relation to their peers, to highlight plants that could potentially be improved and to allow the industry and utilities to track plant performance over time.

Next steps

Following this trial it was deemed that further detailed analysis of the Victorian WWTP benchmarking data was required. The IWN energy group will undertake this analysis in the near future and utilise the results to identify innovative energy efficiency measures that could be implemented across the industry. They will also develop best practice case studies on the high performing water treatment plants to guide the industry, and provide guidance on the use of sub-metering to improve energy management.
