The Southern Growth Area has been designated by the Rural City of Wangaratta as a primary zone for residential development.
This pivotal area, currently in its nascent stages of growth, requires extensive infrastructure upgrades to accommodate the projected population surge.
North East Water has mandated the installation of several new sewer pipelines to support this expansion, integral to managing future housing and community needs.
Adept Civil, a premier civil and water infrastructure contractor based in Victoria, has been selected for this critical task.
The project encompasses the construction of key sewer pipelines, including a 1000m long, 250mm diameter sewer rising main extending from the Salisbury Street sewer pump station along Salisbury Street to Cribbes Road.
Additional works include 710m of gravity sewer pipe varying from 225mm to 300mm diameter west of Salisbury Street and 560m of 300mm diameter gravity sewer pipe along Cribbes Road and Rattray Avenue.
Adept Civil was appointed by Longford Civil, the principal contractor, to undertake the microtunnelling works along Salisbury Street and Rattray Avenue.
The scope involved approximately 350m of 324mm glass reinforced plastic (GRP) pipe installation at various depths.
Adept Civil’s reputation for collaboration and its adeptness at integrating client requirements were pivotal in securing this contract.
The company’s expertise in microtunnelling was crucial for the project’s success.
For the precise execution of this project, Adept Civil employed the Axis GB812 laser-guided boring system. This choice was instrumental in achieving accurate grade drilling and efficient material extraction, minimising environmental impact and community disruption.
One of the significant challenges encountered was the installation of the DN324mm GRP gravity sewer along Cribbes Road, which was completed using microtunnelling due to the pipeline’s alignment in the nature strip.
This method effectively reduced disturbances to residents, mitigated traffic disruptions, and minimised the impact on existing services, vegetation, and infrastructure.
The use of the Axis boring system, with its advanced precision and vacuum extraction capabilities, further ensured a seamless execution.
Established in 1999, Adept Civil has grown into a leading civil infrastructure contractor.
With over 40 professionals, the company is renowned for exceptional civil project delivery and stringent safety and quality standards.
The company specialises in water and sewerage pipelines, pump stations, and associated services, consistently meeting industrial codes.
Adept Civil’s commitment to safety, environment, and ISO certifications positions it as a trusted infrastructure partner.
It holds accreditation from major water authorities like City West Water, Yarra Valley Water, South East Water, and Melbourne Water.
Additionally, it is a Civil Contractors Federation Victoria Branch member and VICROADS accredited, reflecting extensive industry recognition.
