Extracted from Melbourne Water’s
Environment Compliance report Q3 (2012/13)
Waterways
The following information describes the physico-chemical and bacteriological condition of
Melbourne’s waterways during the reporting period. Objectives set out in the three
relevant State environment protection policies (SEPPs) are the long-term targets for
water quality. There is no specific statutory obligation on Melbourne Water to meet
these targets.
This report uses a rolling twelve months of waterway water quality data and uses the
relevant statistical measure from the particular SEPP schedule and segment a waterway
falls within. The performance tables show performance against relevant SEPP objectives
with red indicating a failure to meet SEPP and green indicating compliance with SEPP.
The number in each cell is the result for the previous 12 months and is compared against
the relevant SEPP objective (in blue).
Waterway monitoring data from the last twelve months showed that waterways within
Greater Melbourne performed well for pH, with most catchments complying with SEPP
objectives. Some waterways perform poorly for dissolved oxygen, whilst others in the
Werribee/Maribyrnong and Yarra catchments improved compared to the same period last
year. All waterways performed poorly for nutrient levels and turbidity with most
catchments having few sites that comply with phosphorous, nitrogen, turbidity or E.coli
objectives.
The following charts show SEPP Compliance at Melbourne Water’s monitoring sites.
