Project overview
North East Water is upgrading the Bright-Porepunkah Wastewater Treatment Plant. This upgrade will significantly improve wastewater treatment performance, environmental outcomes and support future population growth in Bright and surrounds.
Sewage from Bright and Porepunkah is currently treated in a lagoon-based wastewater treatment plant that was constructed in 1982. The treated water is released via an infiltration basin which flows via groundwater indirectly to the Ovens River upstream of Porepunkah. This arrangement does not meet current standards, and a new treated water release method is required.
The upgrade works will involve:
- a new mechanical treatment plant including a fit for purpose biological nutrient removal process
- a treated water underground pipeline releasing to the Ovens River downstream of Porepunkah.
Proposed pipeline alignment
In 2024, North East Water considered a range of pipeline alignment options. These options were assessed by the project team and shortlisted based on environmental, social, and economic factors. Feedback on the shortlisted options was sought from key stakeholders and the community via stakeholder briefings, information drop-in sessions, an online survey and this project page.
Shortlisted options were multi-criteria assessed using a range of inputs, including: an ecological risk assessment, river health studies, engineering concepts, and stakeholder and community feedback. The preferred alignment (below) will provide a lower risk to the Ovens River system based on an ecological risk assessment and was a clear community preference based on survey responses and feedback.
Preliminary site investigations to identify the presence of any below-ground services, such as communications or energy cabling have now been completed along with some in-ground geotechnical testing.
Next Steps
North East Water has worked with project consultants Stantec to progress the design of the underground pipeline. As per legislative requirements a Development License Application will be submitted to the Environment Protection Authority (EPA) in mid 2026.
The upgrade works will be tendered following EPA and stakeholder agency approvals.
