Details

Description

Fortescue’s Eliwana Mine Site required the installation of dewatering infrastructure to allow the mining of the Flying Fish ore body. This included a new bore field, pipeline infrastructure, holding tanks and turkey’s nests.

TCD’s key deliverables included:

  • 45km of HDPE pipelines for water supply of the mine, inclusive of 8km of buried pipelines
  • 4 x Turkey’s Nests, each with a LV and HV Standpipe
  • 1 x Transfer Pond and Pump Station
  • 12 x Abstraction Bores
  • 6 x Re-Injection Bores

Whilst on-site additional works were awarded for the pipe re-alignment for the Flying Fish Haul Road, as the current design clashed with the existing pipeline. Works included the installation and re-alignment of piping, valves and fittings.
