Murrumbidgee to Googong Pipeline

The M2G pipeline is an important asset for ACT’s long-term water security.

M2G is a 12-kilometre pipeline that can transfer water from the Murrumbidgee River into the Googong Reservoir when needed.

The M2G pipeline was completed and commissioned in August 2012 as part of a suite of water security projects initiated during the Millennium Drought. The pipeline provides additional water supply in the event that Canberra faces similar drought conditions again.

The pipeline runs approximately three kilometres through the ACT and nine kilometres through NSW. Beginning at Angle Crossing on the Murrumbidgee River in the ACT, the pipeline runs through to the Williamsdale Road crossing of Burra Creek in NSW. The M2G pipeline can transfer up to 100 megalitres of water per day.

We can operate the M2G pipeline in three modes – operating, standby and suspension. Depending on our future water storage levels and climate forecasts, the three modes can be adjusted.

When in suspension mode we can reduce operational expenditure because we do not have to inspect or maintain the assets as frequently.  This ultimately provides an economic benefit for the Canberra community. If we enter a prolonged dry period and water levels drop, the M2G can be switched to operating mode.
