What's this project all about?

The Green Point Sewage Treatment Plant will receive a major upgrade during 2024 – 2025. This includes upgrading the electrical and control systems and the two anaerobic digesters. The plant will also receive a new biogas system.

Upgrading the ageing anaerobic digester and biogas systems will contribute to a more efficient waste treatment process and assist in minimising odour. By improving the systems that the plant utilises to operate effectively, we are ensuring that our infrastructure will meet the needs of the growing Bridgewater community.

We are also undertaking works to improve the Plant's capability to manage and dispose of biosolids as part of this project.

Construction is planned for May 2024, following preliminary works at the Green Point Sewage Treatment Plant from 22 April. Originally planned for completion in early 2025, the works will be extended until September 2025 as we take the opportunity to upgrade other important infrastructure at the Plant.

What will you notice during our works?

There will be construction activity around the Green Point Sewage Treatment Plant including truck movements, heavy equipment, service vehicles, and workers. Those visiting the playground, or regularly attending businesses near the Treatment Plant are advised to be cautious of additional traffic in the area.

To facilitate the project, we will be moving waste from Green Point Sewage Treatment Plant to other Pump Stations to be processed. The initial location is a sewage pump station located on Cadbury Road. Transfer to this Pump Station ceased in July 2024, and we are now transferring waste to Price of Wales Bay Sewage Treatment Plant. Although Cameron Bay remains an option for this process, a starting date has not been confirmed.

You will notice minor increased truck movement at these locations. We are confident that the risk of odour is minimal due to the nature of the technology used during the transfer process.

Most work will take place weekdays Monday to Friday. There will be some waste transfer activity on Saturdays to ensure the plant remains efficient and operational.
