What will the completed site look like?
The project design is being developed in stages, and some details of the completed site are still being finalised. As the design progresses, further information will be provided about the final layout, infrastructure, landscaping and ongoing operation of the site.
Why are excavation and site preparation underway when the final design has not yet been completed?
Some early works can begin before the full design is complete. These include site establishment, initial clearing and geotechnical investigations. The geotechnical investigation works were required to provide information to help inform the design.
The design is being developed and delivered in stages. The first design package covers the main earthworks required for the clarifiers and is expected to be completed in early September. Once this design is finalised, these earthworks can begin.
This staged approach allows the project to progress safely and efficiently while the remaining design is completed.
What is the excavation methodology?
The final reports from the geotechnical investigation are expected in early September. The findings will help determine the most appropriate and safe excavation methodology for the site. At this current stage, blasting is not anticipated.
How will environmental impacts be considered?
Environmental matters will be considered through planning, approvals and delivery. This may include vegetation, waterways, habitat, erosion and sediment control, and any relevant environmental approvals or management requirements.
Where will the new sedimentation tank infrastructure be located?
The new infrastructure will be located within the existing Jones Hill Water Treatment Plant site.
Will roads stay open during construction?
Where possible, roads will remain open with traffic management in place. Temporary changes, delays, detours or short closures may be required at times for safety or construction reasons.
What impacts can the community expect during construction?
Impacts may include temporary noise, dust, vibration, traffic changes, access impacts, vegetation clearing, increased truck movements or works near private property. These impacts will vary depending on the project and location.
Will construction be noisy?
Some construction activities may be noisy. Council and the Alliance will aim to manage noise where possible and provide advance notice for particularly disruptive activities.
Will there be dust or vibration?
Some works may create dust or vibration, depending on the activity and ground conditions. Management measures will be used where appropriate and directly affected stakeholders will be informed where higher-impact activities are expected.
Will there be screening or visual mitigation?
Council will consider reasonable visual mitigation, such as screening or finish treatments, where practical and where not constrained by safety, operations, maintenance, budget or technical requirements.
