Interflow gains national recognition

The Civil Contractors Federation (CCF) has awarded Interflow a significant national award for its project innovation.

The CCF is Australia’s peak civil construction industry body, acting as the nation’s advocate for developments within the industry.

To locate exemplars throughout the field, the CCF Earth Awards unveils leading prospects of infrastructure including roads, bridges, railways, marine structures and utilities.

Specifically, the event recognises civil contracting companies who have recently been involved in a project that has excelled in numerous categories, such as project management, innovation, quality, development and training, safety and stakeholder engagement.

On 22 November 2019, Interflow and John HollandKBR Joint Venture (JH-KBR JV) collected the CCF National Earth Award for its North Yarra Deviation project.

The North Yarra Deviation is a deep section of sewer located under the Stony Creek Backwash where the creek meets the Yarra River, transporting 15–20 per cent of Melbourne’s sewerage at approximately 1,700 L/s during peak dry weather flows.

To complete the project, Interflow assessed suitable technologies and concluded the SPR™ PE – Ribline spiral wound lining system was the most practical rehabilitation solution.

Approximately 75 per cent of the work was completed in a confined space which was successfully navigated by an experienced project team and expert subcontractors.

The North Yarra Deviation project demonstrates how collaboration and innovation can achieve success in difficult pipeline rehabilitation projects.
