Rehabilitation of sewer reticulation pipelines across Southern Sydney

NSW
D4C
In progress

Abergeldie is working with Sydney Water’s delivery partner, D4C to deliver an annual package of work to rehabilitate sewer reticulation pipelines across Sydney’s southern region. The pipelines are relined using trenchless technologies and range in diameter from 150- 300mm.

Scope of works

The annual package of work typically includes:

  • Ex PVC fold and form reline, 150 – 300 mm. 
  • UV Liner System.
  • CIPP Liner.
  • Spot repairs and lateral sealing of junctions.
  • Cleaning, root cutting and CCTV inspections.
  • Excavations.

Using trenchless methodologies to minimise community impact

The works are performed in urban areas and in some cases within national parks impacting residents, businesses, and the broader community. To minimise disruption works are carefully planned and delivered using trenchless methodologies. The Abergeldie team works closely with D4C to ensure appropriate controls to mitigate the impact to the community and the environment while delivering the work safely.


Extending the life of these assets

The sewer renewal works extend the design life of the sewer pipeline, ensuring the integrity of pipe segments between maintenance holes.
