Woolloomooloo sewer and stormwater to be separated by 2020

Media release: 4 August 2016

The NSW Environment Protection Authority (EPA) and Sydney Water Corporation (Sydney Water) have initiated a project to reduce wet weather wastewater overflows to Woolloomooloo Bay.

Woolloomooloo has the only remaining combined sewer and stormwater pipe network in Greater Sydney. There is now a legally binding pollution reduction program on Sydney Water’s Environment Protection Licence which requires the system to be completely separated by 31 December 2019.

EPA Acting Director Metropolitan Greg Sheehy said that the pollution reduction program imposed strict new discharge targets on Sydney Water’s licence for the Bondi Sewage Treatment System.

“Reducing the frequency of overflows will improve public health risks, reduce odours and improve visual impacts,” Mr Sheehy said.

“Currently, the frequency of discharges to the environment during heavy weather events ranges from 299 to 464 times over a ten-year period. However when the upgrade works are completed only 20 overflow events in ten years will be allowed on Sydney Water’s licence.”

Mr Sheehy said the EPA is committed to improving water quality in the greater metro area.

The EPA has been working closely with Sydney Water to put a plan of action in place to upgrade the Woolloomooloo system,” he said.
