Dubbo groundwater supply and drought management strategy

GHD provided hydrogeological and groundwater modelling services to develop a numerical model of part of the Upper Macquarie alluvial aquifer, and evaluation of alternative groundwater extraction options for sustainable water supply to the city of Dubbo.

The Macquarie River at Dubbo, in central-west New South Wales, is a major source of recharge to groundwater in the underlying alluvial aquifers, and both the river and groundwater are vital sources of water to the city of Dubbo. GHD services will allow Dubbo City Council to choose the best pumping scenarios between various bore locations and the river to minimise and share these impacts in the most equitable way.

GHD combined specialist technical expertise with local services through its Dubbo and Orange offices, and an understanding of the practicalities of groundwater extraction in a shared and regulated water system. An understanding of local government water supply requirements, in the context of sustainable groundwater extraction and the state government regulatory framework, was crucial to the success of the project.
