On screen text: The Northern Territory Government respectfully acknowledges Aboriginal and Torres Strait Islander peoples as the First Nations people of this country. We acknowledge the continuing connection to lands, waters and communities, and the evolving cultures of all our First Nations peoples. We pay our respects to all Aboriginal and Torres Strait Islander cultures and to their leaders - past, present and emerging.

On screen text: Darwin region future water supply

The recommended infrastructure solutions:

  • Manton Dam return to service (RTS)
  • Adelaide River Off-stream Water Storage (AROWS).

Male voice over: Water, it’s one of our most precious resources.

[Google Earth map of Australia with the Northern Territory highlighted, zooms into shot of the greater Darwin region]

Male voice over: In the Darwin region, almost all of our water is supplied from the Darwin River Dam.

[Zoom in on Google Earth map to highlight Darwin River Dam]

Male voice over: It has served us well but it’s operating at its capacity.

[Montage aerials of Darwin River Dam, community/urban shots]

Male voice over: To meet future residential demand and our goal to become a $40 billion economy by 2030.

On screen text: Our Target to be a $40 billion economy by 2030 securing our future water supply is critical.

On screen text: Securing our future water supply is critical.

Male voice over: We are focused on supporting jobs for Territorians and are planning for the long term.

On screen text: We are focused on supporting jobs for Territorians.

Male voice over: With funding from the Australian Government, we have completed a detailed business case which has assessed a range of options to increase water supply in the Darwin region.

On screen text: Our response: completed a detailed business case which assessed a range of infrastructure solutions to increase water supply in the Darwin region.

[Front cover of the Detailed Business Case, Australian Government logo, National Water Grid logo]

Male voice over: This comprehensive assessment has identified the best solutions to meet the short and long term needs of the Territory.

[Montage of aerial shots of the Darwin River Dam and Adelaide River]

Male voice over: The short-term solution to provide Territorians with more water, is the return to service of Manton Dam.

On screen text: Stage 1: Manton Dam Return to Service (RTS).

[Zoom in on Google Earth map to highlight Manton Dam]

Male voice over: Manton Dam can supply approximately 7,300ML a year and was Darwin’s primary source of water until the construction and commissioning of the Darwin River Dam in 1972.

On screen text: Manton Dam

  • development timeframe 3 to 4 years
  • capacity of around 14,000ML
  • could supply additional 7,300ML pa
  • reduces water security risks
  • enables short-term economic development.

Male voiceover and on screen text:

The return to service project would include the:

  • refurbishment of the existing dam infrastructure.
  • construction of a new pumping station and pipeline
  • and construction of a new water treatment plant.

Male voice over: So what are the next steps?

The Northern Territory Government is working with the Power and Water Corporation on the best approach to deliver the project, which will include the detailed design of the infrastructure components, stakeholder engagement and an assessment of the environmental and social impacts.

On screen text: Manton Dam RTS

  • detailed design of the infrastructure components
  • stakeholder engagement
  • an assessment of the environmental and social impacts.

Male voice over: The long-term solution to supply more water to the Darwin region is the Adelaide River.

[Zoom in on Google Earth map to highlight Adelaide Off-stream Water Storage project site in proximity to Lake Bennett and the Adelaide River]

Male voice over: Off-stream Water Storage, or AROWS, project, located around 5km directly north of Lake Bennett, adjacent to the Adelaide River.

Male voice over: The proposed storage reservoir is made up largely of a natural ridge formation that can hold water, with the construction of two main containment barriers at low points to store the water within the natural reservoir.

[Aerial shot over the AROWS project site, with animation overlay showing the Adelaide River and the outlet of water from the natural basin. The natural ridge is highlighted and a wall appears to represent where the dam structure will be built to keep the water in]

Male voice over: Water is then extracted from the Adelaide River to fill the reservoir in our wettest months, meaning there is no infrastructure that will dam the river.

[Aerial shot of two boats traveling along the Adelaide River]

On screen text: Importantly there is no dam infrastructure that would restrict the flow of the Adelaide River.

Male voice over: This solution provides a far more environmentally sustainable infrastructure solution compared to a traditional dam.

[Zoom out on Google Earth map to highlight water traveling from the Adelaide River into AROWS, and then out to Straus Water Treatment Plan, before going to customers in Middle Arm, Darwin and Palmerston]

Male voice over: Once extracted from the reservoir, the water will be treated at the proposed Strauss Water Treatment Plant, before distribution to the region.

On screen text: AROWS:

  • development timeframe 7 to 10 years
  • capacity of around 250,000ML
  • could supply additional 60,200ML pa
  • ensures long term water security for the Darwin region
  • unlocks sustainable, long term economic development.

Male voice over: With accelerated project development, the timeframe for delivery is between 7 and 10 years.

What are the next steps?

[Montage of shots over Adelaide River]

Male voice over: The Northern Territory Government is currently working with the Power and Water Corporation to continue a range of project development activities including:

  • a water allocation plan for the Adelaide River catchment
  • an environmental approval process
  • further stakeholder engagement and community consultation.

On screen text: Next steps: AROWS:

  • a water allocation plan for the Adelaide River catchment
  • an environmental approval process
  • further stakeholder engagement and community consultation.

[Background montage of Adelaide River and community images]

Male voice over: Water security is critical.

A new water source is needed to support economic and population growth in the territory

Manton Dam return to service and AROWS will provide long-term water security, regional resilience and unlock economic growth in the region.

As a major water infrastructure project, AROWS is an innovative and sustainable option that minimizes the impact on the environment.

And importantly, there is minimal disruption to our lifestyle.
