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 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.

GHD also tackles the global water and wastewater challenges through International Development Assistance projects, and membership of leading organisations such as the World Business Council for Sustainable Development, the International Water Association and the International Desalination Association, among others.

91st Ave Treatment Plant

image

The 91st Avenue WWTP Chlorination Improvements project involved the replacement of a 120-ton bulk chlorine system with a system consisting of 32 one-ton chlorine cylinders.  The plant has a treatment capacity exceeding 180 mgd. The existing chlorination equipment and piping was replaced while the plant was in full and normal operating condition. The plant’s treated effluent is used at the Tres Rios Wetlands and as cooling water for the Palo Verde Nuclear Generating Station.

The project also involved the development and coordination of the Maintenance of Plant Operation (MOPO) procedures. The chlorination of the plant effluent had to be maintained at all times during construction. The project also included building structural, electrical, and HVAC modifications. The equipment installed included the following:

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

image

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.

Cox Creek Wastewater Treatment Upgrade (Md, USA)

image

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.

Curtis Hixon Waterfront Park, Tampa, FL, USA

image

GHD worked with the City of Tampa to develop mitigation strategies for a flood-prone area in Curtis Hixon Waterfront Park.

A place to meet and enjoy Tampa’s waterfront, Curtis Hixon Waterfront Park overlooking the Hillsborough River is a unique urban design that attracts over 1 million people annually to its special events. The 8-acre park features a sloping Great Lawn with two fountains, a children's playground, public boat docks, a dog park, seat terraces, a pavilion, and a café. The downtown park integrates the Riverwalk, Glazer Children's Museum, and the Tampa Museum of Art.

C.W. Young Regional Reservoir, Tampa, FL, USA

image

GHD was engaged to assess the risk of sinkhole development at the C.W. Bill Young Regional Reservoir. Making the region’s water supply more drought resistant, reliable, and flexible, the 15.5 billion gallon reservoir stores and collects surface water from the Tampa Bypass Canal and Hillsborough and Alafia rivers during wet times. During dry times, water stored in the reservoir is withdrawn, treated, and blended with other supplies to serve the region.

As a result of groundwater pumpage from the Floridan aquifer for crop freeze protection, sinkhole formations were evident in Hillsborough County in 2010. The Florida Department of Environmental Protection (FDEP) was concerned that karst conditions under the Reservoir may have been altered by these rapid drawdown events. Furthermore, the 2014 berm expansion and increase in the reservoir pool may exacerbate the risk of sinkhole development and pose a threat to the safety of the reservoir and its neighbors.

East Pennsboro Township Wastewater Treatment Facility Improvements, East Pennsboro Township, Pennsylvania, USA

image

The East Pennsboro Township Wastewater Treatment Facility in Cumberland County, Pennsylvania, originally a conventional activated sludge wastewater treatment plant permitted at 3.7 million gallons per day (MGD), was recently upgraded to a highly efficient biological nutrient removal (BNR) facility, including the addition of a combined heat and power (CHP) system utilizing biogas.

As part of Pennsylvania’s Chesapeake Bay Tributary Strategy, the plant was required by the Pennsylvania DEP to upgrade the facility to provide nutrient removal. The project also included increasing permitted capacity from 3.7 to 4.4 MGD to accommodate growth within the service area, and improvements to plant hydraulics to accommodate up to 24 MGD peak wet weather flow.

Santa Rosa Urban Reuse

image

The City of Santa Rosa’s water recycling program provides high-quality water for agriculture, energy production and urban uses. Historically, this program was managed for its wastewater disposal benefit.  GHD assisted in the development of the City’s Incremental Recycled Water Program – a 30 year master plan for managing the system. We then led a consulting team tasked with evaluating a range of alternatives for expanding Santa Rosa’s urban water recycling program by up to 6600 acre-feet per year, as one piece of the incremental program.

Because of an increasingly constrained regional water supply, the benefits of urban reuse were studied by the water utility and wastewater utility in partnership. The analysis included over a dozen alternatives for system configuration and size and concluded that a 3000 acre-foot expansion provided the best value for both utilities.
