ACTEW have announced the release of their “Future Sewerage Options Review: Canberra Sewerage Strategy 2010-2060”.
ACTEW Managing Director Mark Sullivan said “the ability to effectively plan, operate, and maintain sewerage assets in a manner that meets community expectations, and meets legislative and regulatory requirements, is becoming increasingly challenging as a result of climate change and variability, population increases and other key factors”.
“ACTEW is at the leading edge with undertaking this sort of strategic review for the sewerage business and this report has confirmed that we are in good shape – that our existing sewerage system is appropriate for the ACT and with some modifications and enhancements will see us well into the future,” said Mr Sullivan.
“However there is a need to undertake further detailed assessment of a variety of issues associated with a drying climate and its impact on our sewerage services,” he said.
The report noted changes will also be required to enable ACTEW to respond to population growth, climate change, environmental pressures and other factors. Further work has commenced to enable ACTEW to continue to deliver effective sewerage services into the future.
The study considers many related aspects including:
- • How should the sewerage system respond to the effects of long term climate change?
• Should potable water continue to be used in the sewerage system?
• Are there new technologies that provide better solutions to managing sewage?
• How should the sewerage system adapt to more households using grey water?
• Can recycled water be used more productively in the ACT than in irrigation areas downstream?
• How does the Murray-Darling Basin Cap influence the use of recycled water?
• Can the sewerage system be changed to use less energy and reduce greenhouse gas (GHG) emissions?
• Can better treatment and effluent quality achieve better environmental outcomes?
• Can stormwater and roof water play a role in the future sewerage system?
• Which emerging issues in public health, utility management or environmental concerns will require changes in current practices?
