To service forecast increased population levels<\/strong><\/p>\n<\/div> Bundaberg Regional Council embarked on a $90M project to construct a new waste water treatment plant at Rubyanna, located between the towns of Bundaberg and Bargara in central Queensland<\/strong><\/p>\n<\/div> As part of this treatment plant, a new discharge was required into the Burnett River.<\/p>\n The river discharge was procured as a design and construct contract, for a scope of works including a 150m long discharge pipeline and an onshore overflow pit.\u00a0\u00a0<\/p>\n Brady Marine & Civil developed an optimised design and methodology which required less materials, reduced environmental impacts and was able to be constructed in a shorter time period.<\/p>\n<\/div> Scope of works included:<\/strong><\/p>\n <\/span><\/li>\n<\/ul>\n Special Features<\/b><\/p>\n A single 1200mm diameter pipeline which had been indicated in the original concept design was replaced by two 900mm pipelines.\u00a0 These were set parallel, each ending with half the required number of diffuser ports.\u00a0 As well as reducing by one third the required number of offshore supporting piles, this arrangement enabled the completed facility to better deal with a staged capacity as the WWTP inflows grew steadily in the future.<\/span><\/p>\n Through optimising the alignment, chainage and support of the discharge pipelines, all offshore dredging was eliminated in Brady Marine\u2019s solution.\u00a0 This meant that no dredged spoil needed to be disposed of and also meant than no scour rock was required to be supplied or placed offshore as the existing seabed was not disturbed.\u00a0<\/span><\/p>\n With a smaller pipeline diameter, our solution utilised trenchless technology to enable the pipelines to be installed to an exit point in the river without impacting on the existing shoreline.\u00a0 In so doing this avoided the need for shoring and construction access through the riverbank, eliminated any damage to the natural shoreline and associated flora and saved any requirement for scour protection after laying the pipe.<\/span><\/p>\n\n
