Plans reopened to raise Warragamba dam

Start the conversation

The Department of Planning and Environment (DPE) is calling for further community input on a proposal to raise Warragamba Dam wall.

In a statement, WaterNSW said its proposal to raise the wall by 14 metres responded to a 2017 Infrastructure NSW Strategy recommendation to reduce the risks to life, property and community assets posed by floodwaters from the extensive Warragamba River catchment.

“[The Hawkesbury-Nepean Valley Flood Risk Management Strategy] recommends that raising Warragamba Dam to create a flood mitigation zone of around 14 metres is the best option,” WaterNSW said.

A spokesperson for DPE said the Department had now requested WaterNSW provide a Preferred Infrastructure Report (PIR), detailing further information and any changes on the proposal in response to matters raised during last year’s consultation.

They said the PIR was requested from WaterNSW following the level of interest and issues raised by State Agencies.

“The community can lodge submissions up until midnight Monday 12 December, and then WaterNSW will provide a second Response to Submissions Report,” the spokesperson said.

“Once it receives WaterNSW’s response, the Department will undertake an assessment of the proposal, before providing its final report and recommendation to the Minister for Planning and Minister for Homes, who will be responsible for making the final decision.”
