GHD is at the forefront of the water industry, delivering sustainable water solutions across the globe, covering every element of the water cycle for urban, rural and industrial water applications.

As the world’s population grows and our standards of living improve so does our need to manage the water in our environment. We need to maximise its application for human well-being and minimise impact on the environment. GHD engineers, scientists and planners can provide sustainable, cost-effective and innovative water solutions.  We assist water utilities and others who provide water services to optimise infrastructure and adapt to environmental changes in ways that balance the needs of our communities. And we enable clients to meet compliance, improve profitability and maintain their commitment to sustainability.

GHD continually expands the boundaries by engaging in research, enhancing existing systems and strategies, evaluating new procedures and transferring technology from other industries into the water industry. We work with our clients through all project stages planning, investigation, design, delivery, operation and renewal.

The end result is GHD is delivering significant projects all over the world. Examples include desalination plant work in Australia, USA, Mexico, Africa and the Middle East; major water recycling projects like the Western Corridor Recycled Water project in Australia; and work on a wastewater treatment plant so that it meets high nutrient removal standards to protect the quality of water in Chesapeake Bay in the USA. But significance is relative. Every project is important to our clients and we at GHD pride ourselves on the efficient and effective delivery of every commission large or small.

We're proud of our formidable knowledge-base, and we've won many industry awards for innovation and outstanding project delivery.

Ammonia Phosphorus Removal, Metropolitan Syracuse Treatment Plant Onondaga County (NY, USA)


In partnership with two other firms GHD was retained by Onondaga County, New York to provide engineering services in connection with the design and construction of improvements to its 84 million-gallon-per day Metropolitan (METRO) wastewater treatment plant, with the objective of upgrading the level of wastewater treatment provided for ammonia and phosphorus removal.

The project established that the facility, which provided conventional secondary treatment (with seasonal nitrification and phosphorus removal to less than 1.0 mg/L), needed to be upgraded to provide year-round ammonia removal (1.0 mg/L as N for June 1st to October 31st, and 2.0 mg/L for November 1st to May 31st), and phosphorus removal to 0.12 mg/L TP for a 12-month rolling average.

Carlsbad Desalination Plant (CA, USA)


GHD in collaboration with Butier Engineering were selected by Poseidon Resources to provide Owner's Engineering services for the development, construction and commissioning of the 50 MGD Carlsbad Seawater Desalination project. 

As Owner’s Engineer, GHD and Butier have and continue to provide general oversight and independent assessment of the performance of the Engineering Procurement Construction (EPC) Contractor relative to the delivery of the Carlsbad project.

Cox Creek Wastewater Treatment Upgrade (Md, USA)


GHD was retained by Anne Arundel County for the Enhanced Nutrient Removal (ENR) Upgrade of the Cox Creek Water Reclamation Facility (WRF). The 15.0 mgd (56.7 ML/d) Cox Creek WRF is the largest of the County’s seven (7) major wastewater treatment facilities and is also the County’s largest single contributor of nitrogen and phosphorus to the Chesapeake Bay. 

During the facilities planning phase, a comprehensive examination was made of all plant unit processes and hydraulics.  As part of this project, a decision was made to expand the peak day hydraulic capacity of the facility from 30 to 45 mgd (113 to 170 ML/d) to accommodate observed I/I derived peak flows. ENR alternatives were evaluated in a two-step approach with the first step shortlisting to three alternatives and the second step selecting the final recommendation based on conceptual designs and lifecycle cost analysis. A Membrane Bioreactor (MBR) process was selected to replace the existing MLE process. MBRs proved to be the right choice for the Cox Creek WRF due to very tight site constraints, inadequate existing reactor volume to fully nitrify year-round, inadequate existing secondary clarification facilities, limited hydraulic head available for process modifications, and the County’s desire to produce as high of quality of effluent as possible with the maximum degree of reliability.

Securing Canberra’s water supply (ACT, Australia)


GHD’s work with the ACT Electricity and Water Corp (ACTEW) on the Cotter Dam is helping to secure the territory’s water supply and raising the bar for sustainable construction. The AUD363 million project involves building a new 80 metre high wall to increase the main dam’s capacity from 4 gigalitres to 78 gigalitres, and building two saddle dams with walls 15-20 m high.

Working in an alliance with ACTEW and construction companies Abigroup and John Holland, GHD has been responsible for engineering design, stakeholder liaison, environmental approvals and safety and quality control during construction. GHD’s analysis identified the best location for the dam wall, and a cost-effective construction method using roller compacted concrete (RCC).

Western Corridor Recycled Water Project (Qld, Australia)

The AUD$2.5 billion Western Corridor Recycled Water Project is Australia’s largest water recycling scheme and the third-largest advanced water treatment project in the world.

It uses secondary wastewater from Brisbane and Ipswich, to produce 232Ml of purified recycled water a day. The project is the Queensland State Government’s response to unprecedented demand on its water supply due to population growth, climate change and the worst drought in recorded history.

Murray River wetland rehabilitation (Vic, Australia)


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.
