Wastewater – Arthurs Supply Pipeline

The Arthurs Lake Supply Pipeline is a vital part of Tasmania’s irrigation scheme, with high pressure pipe through to the mini-hydro power station capable of generating 7.1MW of electricity. Approximately 22% of the generated power is used by pumping stations for the onward distribution of water. The remaining power is sold into the local power grid via a 15km 22kv transmission line constructed by Fulton Hogan as part of the scheme.

The water from this scheme is helping turn the Midlands Region into a more diverse agricultural area, traditionally used only for grazing, rather than cropping due to low rainfall.

Fulton Hogan’s scope of work included:

  • Pipe intake structure
  • 5km 1000mm ductile iron cement lined pipe
  • 5 Km 813mm dia mild steel cement lined pipe
  • 1 megawatt hydro power station
  • 15 km of high voltage power lines
  • Anti-Islanding System
  • HV Switchroom
