Living and working locally means that our teams are able to develop closer working relationships with our clients. We understand the local context in which projects are undertaken including the local drivers, stakeholders and the particular issues and challenges for projects in the local area. Our teams have experience working for government and private clients alike.

While our clients value our regional experience and understanding of the local context they also value our ability to draw on the experience and specialist services from across the GHD network when a project demands additional resources or a particular skill set or experience that is not available locally. We manage these additional resources from our local base, meaning costs are appropriately controlled and solutions are matched to local requirements and expectations.

Australian Plantation Forestry Climate Change

Orange Waste Project


GHD was engaged to prepare an environmental assessment (EA) to assist with the development of a new resource recovery plan and transfer facility as well as new composting and landfilling operations in the New South Wales district of Orange. The project is an integrated resource recovery and waste management scheme that promises to be a model for sustainable regional waste management. Our team also designed one of Australia's first baled waste land fills for their Euchareena Road site.

Working with Orange City Council and a range of groups providing inputs, our team coordinated and prepared the EA document as well as prepared concept designs for the landfill and enclosed tunnel composting facility at Euchareena Road Resource Recovery Centre to support the application.

Rylstone Kandos Project – investigation of alternative water supply


Like many regional towns in Australia, the towns of Rylstone and Kandos and the villages of Charbon and Clandulla have experienced extensive periods of water restrictions. This is due to a relatively small dam and rainfall variability. This lack of water security prompted the Mid-Western Regional Council in New South Wales to engage GHD to investigate alternative water supply strategies.

GHD considered options such as groundwater, long distance pipelines from alternative dams, indirect potable reuse and buyback of water licences from upstream irrigators.
