We see the need for irrigation solutions as a requirement that extends beyond today and into the future.

Our engineers, scientists and planners can provide sustainable, cost-effective and innovative irrigation solutions that meet the needs of communities, industry and national policy and strategy.

GHD provides comprehensive, innovative and independent services to the irrigation industry — services that address the current challenges of water scarcity or over-supply, salinity, modernisation, efficiency and environmental water management. We also consider water infrastructure, systems managements and remodelling.

We’ll work hand in hand with you to balance the sometimes competing demands of agriculture, industry, community and ecosystems.


  • Strategic policy
  • Planning
  • Institutional reviews
  • Environmental science
  • Stakeholder and community engagement
  • Design and construction
  • Triple bottom line solutions
  • Rural water management
  • Irrigation reconfiguration
  • Off-farm and on-farm water use efficiency
  • Surface and acquifer storage of off peak water 
  • Water accounting and salinity assessment 

Engage us and you’ll better understand water markets and skills in catchment planning and management, integrated water cycle management and institutional reviews.

Climate Change impacts study


The Victorian Department of Sustainability and Environment engaged GHD to compare the effects of three different climate scenarios on River Red gum communities in northern Victoria.

The study focused on the likely changes to the frequency, duration, interval and extent of flooding of River Red Gum communities along the Murray.

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.

Greengrove Effluent Irrigation Scheme


The Greengrove Effluent Irrigation Scheme is Dubbo City Council’s practical and far-sighted response to serious waste disposal, environmental and urban issues following toxic algae blooms in the Murray-Darling Basin.

Dubbo City Council engaged GHD (in conjunction with the NSW Department of Commerce, NSW Department of Energy and Utilities & Sustainability) as the head contractor responsible for constructing and commissioning the scheme. The scheme consists of 208ha of centre pivot irrigation, related infrastructure and paddock preparation. Our team also has an ongoing role in the scheme’s operation and management.

Murray River wetland rehabilitation


Known as the Wetland Rehabilitation Project – Reinstating Wetting and Drying Regimes, this is one of the first projects of its type in Australia. The Lower Murray-Darling Catchment Management Authority engaged GHD to investigate, design and implement rehabilitation works to restore flood flows and fish passage to approximately 700ha of wetlands.

The team investigated wetland ecosystems to identify environmental values, then used this information to propose works and complementary land management activities aimed at achieving specific rehabilitation objectives for each wetland. The process involved flora, fauna and aquatic assessments, grazing pressure and land management assessments, indigenous cultural heritage assessments, and hydrologic-hydraulic simulation of proposed water regime options.

Water Allocation Planning – Mt Lofty Ranges


GHD was engaged by the Department of Water, Land and Biodiversity Conservation in South Australia to develop water allocation plans for the Eastern and Western Mount Lofty Ranges Prescribed Water Resources.

The project involved providing advice on water allocations to existing users and water trading rules for consideration in the Water Allocation Plan. There were three main objectives of this project including:

Water Plan for Wimmera Irrigation Upgrade Plan for Wimmera (Vic, Australia)


GHD has been appointed by GWMWater to develop a modernisation plan for the Wimmera Irrigation Area in north-west Victoria.

The plan will consider the options available to increase the efficiency of the Wimmera’s irrigation system, taking into account issues such as climate change and the availability of water in the future.

Waterproofing the South Stage 1


GHD was engaged as the lead consultant for the detailed design of two wetlands, two detention basins, a 93 ML storage dam at Wilfred Taylor Reserve and approximately 18 km of non-potable water distribution network to harvest 850 ML per annum of stormwater runoff from the Christie Creek catchment.

The scope of the project includes:
