A significant environmental threat looms over Sydney Harbour as a damaged underground sewage pipe requires urgent attention to prevent a potential waste spill. Authorities have swiftly commenced emergency repairs to address this critical issue.

The problematic pipe, located approximately eight meters beneath the Pier Street ramp at Darling Harbour, was discovered to have a crack a few weeks ago. Although Sydney Water has reported that the leak is currently contained and stable, they caution that the pipe remains at risk of failing completely.

In response to the potential hazard, around-the-clock emergency operations are underway in the areas of Ultimo, Glebe, and Pyrmont. Part of the strategy involves the construction of a wastewater pumping station at Wentworth Park, which will serve to reroute sewage away from the compromised infrastructure.

Water Minister Rose Jackson emphasized the urgency of these measures, underscoring their importance in preventing a catastrophic spill into the cherished waters of Sydney Harbour. “We don’t want to see any of that. We love our harbour, it’s a pristine place, and we really want to protect it from any environmental impact,” she stated, highlighting the government’s commitment to safeguarding this iconic natural treasure.

Water Minister Rose Jackson said the works were necessary to avoid the worst-case scenario of sewage spilling into the Sydney Harbour.

“We don’t want to see any of that. We love our harbour, it’s a pristine place, and we really want to protect it from any environmental impact,” she said.

“Which is why we are getting in there, doing 24/7 construction to try and make sure that even the small risk of that is removed.” 

Workers are trying to determine the cause of the leak and the size of the crack. Jackson said the 100-year-old infrastructure created further issues.

The sewage is expected to be partially diverted by December 19 and fully diverted by January.

Jackson said nearby residents would be impacted by construction noise, traffic and potential road closures and apologised to the community.

“None of these things are things that we want to do. We know it’s a difficult time of year to be having those kind of impacts on this local community,” she said.

“It is necessary. We’ve identified and contained the leak that we have, but if we don’t act now, things could get worse.”

When the diversions are in place and the pipe is fully isolated, crews can begin to work on a permanent repair.

That may take months to complete. 

Sydney Water is monitoring water quality and working with environmental regulators to ensure there is no impact on public health or the environment.

It is also working with the council, residents and businesses to minimise the impacts of construction.

As for now, waste services are operating as normal for the local community.
