Abergeldie has a long-term collaborative relationship Gold Coast City Council extending over 10+ years to deliver the annual Stormwater Relining Program. Scope includes repairing and renewing the city’s stormwater pipe infrastructure using cost-effective methods to extend the service life of the city’s infrastructure assets whilst also improving the city’s flood resilience. 

Scope of Works

The scope of work has included:

  • CIPP (UV, Steam & Water cured), Spiral, Fold and Form and geo-cast spray relining
  • HDD pipe installation
  • CCTV, high-pressure and vacuum cleaning
  • Barrier dams
  • Community Engagement & notifications
  • Traffic Control
  • Subcontractor Management

The pipe diameters on this program have varied from 300mm up to 1350mm. To date more than 400 stormwater pipe assets have been rehabilitated, to a value of over $12m, with over 19km of installations completed.

Innovative solutions to overcome coastal challenges

Over 80% of the works were affected by the tide heights of the Gold Coast seaway. Various techniques to isolate the outlet pipes were trialed and ultimately successfully completed. Adjustments to the lining designs and installation techniques were also required as some of the works were completed underwater.

Throughout the program, techniques to prepare the pipes for rehabilitation have been adjusted to compensate for the removal of oyster shells in the pipe, mostly utilizing high pressure cleaning methods. The cornerstone solution for this rehabilitation program has been Abergeldie’s Enviroliner CIPP. This solution creates a new pipe-within an existing one, extending the life and serviceability of the asset for several more decades.

Network renewal with minimal disruption

Through the use of trenchless technology, Gold Coast’s residents, businesses, and visitors have seen their stormwater network renewed without the disruption that typically comes with conventional replacement methods.
