Performance assessment of the 60,000 EP Orange STP (MLE) for Orange City Council (NSW).

Orange City Council commissioned a pro-active study into sub-optimal performance and licence compliance at their major facility, Orange STP.  A combination of tightening limits and waning performance has increased the risk of licence breaches in a number of areas.  ASpect reviewed performance data to determine the frequency and extent of performance excursions against licence limits and other benchmarks.  Performance shortfalls were identified (TN, TP, NHx-N, F-Coli and Cl) and analysed in detail to determine the most likely causes.  Operational and small scale capital strategies were recommended and prioritised to reduce the risk of licence breaches in the future.
