Northern Georges River Submain - Wastewater Upgrade

Project timing: May 2024 to August 2025

We’re upgrading 3 km section of a large wastewater main knows as the Northern Georges River Submain. This system services the community from Fairfield to Arncliffe. Our work will increase the capacity within the tunnel, improving its function and reliability of your wastewater service.

Most of our work is underground, however we will have four major sites set up above ground for access into the wastewater system and desilting activities.

Work involves:

Site establishment and traffic management

• four major sites and four minor sites will be set up in suburbs Arncliffe, Rockdale and Kogarah
• The site in Kogarah is located on Gladstone Avenue - you will notice a temporary change to the pedestrian walkway around the compound area - for your safety please follow the traffic and pedestrian signs.

Desilting (removing silt and debris from within the system)

• We expect to remove a total of approximately 1360 tonnes from the asset
• we will be desilting from Vincents Avenue, Rockdale and Subway Road, Rockdale
• there will be changes to local traffic and increased truck movements for deliveries and the disposal of silt and debris.

Tunnel Repairs

• cleaning and surface preparation
• removal and replacement of internal structures (ladders, step irons within the wastewater tunnel
• core hole drilling and final inspection.

Restoration

• Once the above work is finished, all sites will be disestablished and impacted areas will be restored. All restoration works will be performed in accordance with Council and Traffic NSW requirements.

Work hours: 7 am to 6 pm, Monday to Friday. 8 am to 1 pm Saturdays (if required) No work is planned for Sunday or public holidays.
