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

Alkimos Wastewater Treatment Plant

image

GHD was engaged by the Water Corporation in Western Australia to design the AUD80 million 20 ML/d Alkimos Wastewater Treatment Plant as part of the Alkimos Water Alliance (AWA) comprising Multiplex, McMahon and Zublin.

The design incorporates the main elements of the wastewater treatment process, including two x 50m diameter secondary sedimentation tanks, three x 15ML oxidation ditches, inlet works, sludge thickening and odour control.

Asset Management Information System Integrations, Manila Water

image

Manila Water engaged GHD to develop and implement its asset management information system blueprint, as part of an Enterprise Asset Management (EAM) improvement program. Our role included development, tendering, contract management and implementation.

In addition to the blueprint, we developed a comprehensive plan for 34 identified integrations, involving nine different systems (SAP, Works Management, Capital Works, GIS, SCADA, Finance, Business Intelligence, Customer Relationship Management & Metering).

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.

Koondrook-Perricoota Forest, NSW: Vegetation Condition Monitoring Program

image

GHD is assisting the Murray-Darling Basin Authority (through Forestry Corporation of NSW) to understand the response of the iconic Koondrook-Perricoota Forest to flooding and the application of ‘environmental water.’ The forest forms part of the second largest River Red-gum floodplain forest in Australia and has been under significant stress in recent decades due to river regulation and drought.

Since 2013, GHD has undertaken a five-year forest-wide monitoring program to determine change in vegetation condition in wetlands, forest understorey, individual trees and the overall forest stand.

Stormwater Run-off Treatment Facility

image

Adelaide City Council previously had issues with controlling stormwater run-off containing organic and other contaminants from a green waste facility in Adelaide’s parklands, adjacent to the Torrens River.

The council engaged GHD to undertake an investigation related to run-off volumes and contaminants, which identified there was an environmental risk associated with release of the stormwater from the site.

Water Treatment Automation and Centralisation (A+Ction)

image

As part of the A’Ction Alliance comprising GHD, Leicon-Notley and the Water Corporation Alliance, we have played a key role in an AUD50M brownfield treatment control system and SCADA upgrade project.

The project was initiated to raise the level of automation, reduce the need for operator intervention onsite and allow remote monitoring and operator control as well as enhance site security. Works included the automation and control of six metropolitan Water Treatment Plants (WTP), two regional water treatment plants and extensive borefields associated with the treatment plants.
