ACT Basin Priority Project

This project by the ACT Government has registered for a Planning IS Rating.


The ACT is at the top of the Murray Darling Basin, making the treatment of storm water important to water flowing into the Murrumbidgee river and down-stream through NSW, Victoria and South Australia. Storm water treatment involves reducing organic nutrients that arise from low-to-medium flow from rain fall events, by slowing down and filtering sediment. This is best achieved through a distributed water quality options that can treat complex water-flows from around the catchment.

Six catchments were identified for prioritisation of water quality options across the ACT. On 4 December, the ACT Government’s Environment and Planning Directorate submitted a business case to the Commonwealth for funding, under an inter-jurisdictional agreement on water management, to design and construct priority projects to improve storm-water quality across the six catchments. The Commonwealth has indicated informally that the business case will meet due diligence requirements, and that funding will be approved for CAPEX (design and construction) of about $80m.

Although the total CAPEX may not be large by comparison, for example, to major transport infrastructure projects, the program of projects is made complex by the number and different types of projects to be implemented. The water quality projects include construction of wetlands and bio-retention systems, and other water quality options. This is to be achieved within a short time frame and few growing seasons to establish vegetation. It is anticipated that there will be 25 projects in all, 6 consultants, and the program of projects managed centrally by the Environment and Planning Directorate, for completion by mid-2019. Early project design in underway.
