Integrated Water Management

Share on:

The sustainable management of water is one of the key challenges facing our society today. As decision makers, we need to take an informed and holistic approach to the sustainable and secure management of a valuable resource.

Integrated Water Management (IWM) is a strategy that brings together all facets of the water cycle — water supply, sewage management, water treatment and stormwater management — to achieve strong triple bottom line benefits.

Around the globe, we now recognise that water demand and water supply are not in balance. Our professionals understand the interrelation and importance of water reuse, stormwater, groundwater and seawater as essential additions to the traditional water sources from dams and rivers. We offer IWM strategies that are inclusive of these sources and provide long-term sustainable solutions.

With more than 80 years of experience in the management and delivery of water services to the community, GHD’s water gurus understand the correlation between all water cycle elements.

Our people can deliver IWM schemes to benefit organisations and communities through superior energy efficiency, low embedded energy materials and liveable, sustainable community environments

Botany Area Servicing Strategy

image

The Botany Area Plan project aims to provide an integrated strategy for managing water, wastewater, recycled water and stormwater infrastructure in order to provide safe, reliable and sustainable water services. These services will meet the needs of urban growth in the Botany area, while complying with the requirements of Sydney Water Corporation’s (SWC) operating and Environmental Projection Licences (EPLs).

The Botany area is close to Sydney's CBD. Redevelopment plans for the area are underway and some development has already started. The Botany area includes the infill growth areas of Redfern/Waterloo, Green Square, Wolli Creek, Cooks Cove and Sydney Airport. This project also takes these areas into account. In addition, the plan boundary incorporates the areas of Alexandria/Mascot, Botany Banksmeadow and North Arncliffe as they include minor growth pockets that needed to be considered.

Development of an Alternative Water Atlas

image

Client: Smart Water Fund, representing Melbourne Water, City West Water, Yarra Valley Water, South East Water and the Department of Sustainability and Environment Melbourne is a rapidly growing urban centre that has experienced the risks and changes associated with climate variability, as an extended drought saw water supply dam levels fall to approximately 25% capacity during 2009.

Since 2009, issues surrounding both current and future water supplies and costs have become increasingly present in politics and the media.

Gracetown Sustainable Living, Western Australia

image

The existing town of Gracetown is built on 27ha of steeply sloping ground rising from the south-eastern shore of the north-facing Cowaramup Bay in Western Australia. The lowest part of the town is set back from the beach approximately 100m from the shoreline and is approximately 10m above sea level.

The existing town extends approximately 0.5 km up the slope to an elevation of approximately 90m Australian Height Datum. The underlying geology is characterised by shallow weathered limestone-based sands and limestone overlying a granite bedrock (at depths of approximately 20-30m below ground level).

Kanawha River, West Virginia

image

Our client is completing an investigation of a 14-mile section of the Kanawha River near Nitro, West Virginia, under the Removal Action program for the United States Environmental Protection agency (USEPA). The river is partially controlled by a series of locks and dams, and is a major transportation route for coal and other materials. The investigation was completed in three phases:

  • Assembly and detailed review of existing information to develop a Site Conceptual Model (CSM)
  • Refining the CSM through focused sampling, including fish tissue, surface water quality, natural recovery analysis, and sediment quality
  • Additional sediment sampling to fill in data gaps to support remedy selection

Based on this information, GHD developed a detailed understanding of site conditions and recovery trends. We developed a 3D hydrodynamic model to support the evaluation of recovery trends and remedy selection. GHD completed human health and ecological risk assessments for the site and developed preliminary remediation goals.

Regulating Murray River Flows (Australia)

image

Improving the environmental health of the Murray River is a concern for all Australians. The Murray Darling Basin Authority regulates the river system. It offered to pay landholders affected by the release of water from storages.

GHD worked with the Murray Darling Basin Authority, the community and technical experts to identify the impact of released water on floodplain properties, to develop consistent assessment principles and to register the impact on title via easements.

Willow Run Creek Site, Michigan

image

The Willow Run Creek Site involved the remediation of over 340,000 cubic yards of polychlorinated biphenyl impacted sediments and soil. GHD developed a program of pre-design studies, including pilot-scale dredging/dewatering studies, to determine the optimal method of sediment removal and processing.

The selected remedy involved dewatering of the work area, water treatment, and solidification of the sediments to provide the necessary strength for placement in a site-dedicated consolidation disposal facility (CDF). The CDF was designed to meet stringent Toxic Substances Control Act (TSCA) and Resource Conservation and Recovery Act (RCRA) hazardous waste disposal facility standards.
