The Lawler Labor Government is securing the future supply of water for the Darwin and Palmerston regions, with work on the Manton Dam Return to Service project underway.
The project supports the Northern Territory Government's strategic efforts to supply Territorians with safe, reliable, secure water now and into the future.
The Manton Dam project will enable an additional 14 gigalitres of useable water storage capacity and make 7,300 GL per annum available for productive use.
This project will provide an additional 7.3 GL per annum to the Darwin region each year. The equivalent of 2920 Olympic sized swimming pools.
The project consists of three significant packages of work, all due for completion by mid-2026:
· Upgrading the existing dam inlet tower, the construction of a new 20 megalitre/day pump station
· The installation of a new pipeline from Manton to Strauss (Stuart Highway/Cox Peninsula Rd)
· Construction of a new 20ML/Day Water Treatment Plant at Strauss
This project is a partnership between the Northern Territory Government and the Australian Government's National Water Grid, which will see more than $300 million invested in the Darwin Region Water Supply Infrastructure Program to secure a long-term sustainable water supply by 2031.
As well as returning Manton Dam to service, the NWG program also includes the Adelaide River Off-Stream Water Storage (AROWS) project.
The $134 million design and construction tender was successfully awarded to Exact Contracting Pty Ltd in May 2024.
Power and Water will apply additional treatment measures to ensure the water sourced from the dam meets stringent drinking water quality standards.
Manton Dam will remain a recreational resource and a recreation management plan will be developed in collaboration with the Northern Territory Government and in consultation with Territorians.
