Summary: Water quality in this sub-catchment is unknown because so water quality monitoring has been conducted.
Issues: Sewerage pollution from aged and leaking systems and faulty sewerage pumping stations (SPSs) are potential sources of pollution. There are large areas of open space in this sub-catchment and they may be sources of high nutrients.
Knowledge Gaps: No information exists on this sub-catchment with regard to sewerage overflows, stormwater outlets or water quality.
Recommendations: The locations of stormwater outlets and sewerage overflows should be collected. The condition of the sewerage system should be assessed. Water quality monitoring should be conducted on a regular basis.
