AECOM has recently completed the design for a new major sewer rising main with Townsville Council (QLD), to link the recently constructed pump station adjacent to Yolanda Drive with the Cleveland Bay Sewage Treatment Facility.
This project will significantly enhance the performance of the sewage system in the suburbs of Douglas, Annandale, Idalia, Murray, Oonoonba, Wulguru, Stuart and Cluden.
It will also support significant facilities including Townsville Hospital, Lavarack Barracks, James Cook University and the Townsville Correctional Centre.
The already constructed pump station and the yet to be built pipeline, will cost approximately $30m.
The 11.15km pipeline will run mainly in existing drainage and road reserves through Annandale and Idalia before crossing the Townsville State Development Area to Cleveland Bay.
The design includes:
- A 710mm diameter pipeline installed through Annandale, Murray and Idalia mainly using open trench construction except for some road crossings.
- A 900mm diameter pipeline will link to an existing sewer main in Oonoonba. This pipeline will continue, again mainly using open trench construction, to Cleveland Bay.
Construction:
Generally open trench construction will be utilised during construction, except when crossing major roadways and the railway line. Trenchless directional boring methods will be used to reduce surface disruption at these times. Safety fencing, signage and traffic control will be in place during construction to keep residents and motorists safe.
