Sydney Water will separate Sydney’s last remaining combined stormwater and wastewater system at Woolloomooloo, in a project that will include the construction of new pipes.
The system is one of five original combined systems built in the 1800s, and currently collects wastewater and stormwater in the same pipe and transports it for treatment at the Bondi Wastewater Treatment Plant.
“The $45 million Woolloomooloo separation project will significantly reduce diluted wastewater discharges into the bay and further improve Sydney’s harbour,” said Acting General Manager, Liveable City Solutions, Kaia Hodge.
“This is a significant milestone for Sydney and the Woolloomooloo Bay area in particular.”
Once the separation work is completed, the system capacity will be enhanced which will significantly reduce wet weather wastewater discharges into the bay.
“The project will be a win for the residents and the environment,” Ms Hodge said.
The Woolloomooloo separation project will involve:
- Constructing of about 4.2kms of new wastewater pipes
- Connecting about 220 properties to the new system
- Building of 650m of new stormwater pipes
Construction on the Woolloomooloo separation project will begin in early 2017 and take approximately 24 months to complete.
