Sydney Water apologises for wastewater overflow into Parramatta River

Media statement

21 October

Sydney Water has responded urgently this morning to an issue which unfortunately is causing a large volume of untreated wastewater to flow into the Parramatta River from a wastewater pumping station at Northmead. The cause of the incident is still being determined.

Our first priority is to contain the overflow and protect the waterway. We have set up bypass arrangements and expect to be able to control the flow by late afternoon today. We have also arranged for large tankers to attend the site to commence pumping out of the wastewater. We apologise for any inconvenience this may cause to residents in the area.

Sydney Water has signage in place around the site to alert the local community and we have notified all relevant authorities including local councils. Our initial sampling shows minimal impact to Parramatta River due to diluted inflows because of the recent rain. Sydney Water will continue to monitor water quality through the day.

Sydney Water takes its responsibility to protect public health and the environment seriously, and we will conduct a full investigation of this incident to prevent it from happening again across our network.
