A major construction tender has been awarded to a local Territory company which will support over 200 workers.

The Territory Labor Government has taken a major step forward in securing the future water supply of the Darwin region by awarding the design and construction tender of the Manton Dam Return to Service project.

Northern Territory Company Exact Contracting Pty Ltd has been awarded the $134 million contract, to deliver this project.

The Manton Dam Return to Service project is part of Stage 1 of the Darwin Region Water Supply Program, which includes the Adelaide River Off-stream Water Storage (AROWS) project.

The Territory Labor Government and Power and Water are delivering the Program in partnership with the Australian Government’s National Water Grid which has committed over $300 million to support the delivery of the first stage to secure Darwin’s water supply for the long term.
