Project overview

The project includes returning the Manton Dam to service and preconstruction works for the Adelaide River Off-Stream Water Storage (AROWS) project.

Work to return the Manton Dam to service will involve upgrading existing dam infrastructure and building the first phase of the Strauss Water Treatment Plan and distribution network.

The project will enable an additional 14 gigalitres (GL) of usable water storage capacity and make 7,300 GL per annum available for productive use.

Work on the AROWS project includes an environmental impact assessment, pre-tender concept design, delivery model assessment, and re-confirmation of financial and economic outcomes.

Construction to return Manton Dam to service is expected to commence in mid-2024.
