Waste Management

Share on:

Waste avoidance, recovery and reuse of discarded materials, effective landfill management and responsible management of hazardous wastes are all critical elements of sustainable development.

The need to minimise waste generation rates and recover and utilise by-products of waste degradation (through alternative waste treatment technologies or modifications to current waste disposal methods) is dictating the future of waste management practices.

Our team of professionals provide advice and solutions for the complete range of waste management issues. We’ll assist you in developing sustainable practices to address your requirements now and into the future.

We work closely with environmental planners, scientists and community consultants to deliver an integrated, full cycle service to our clients.

Services:

  • Detailed and conceptual design for landfills, transfer stations, resources recovery facilities, containment cells, leachate and rehabilitation
  • Environmental management including modelling, monitoring, collection, assessments, compliance, industrial (solid/liquid) minimisation and cleaner production
  • Strategic planning for siting, resource and waste management, financial modelling and recycling or resource recovery
  • Legislative approvals and considerations including approvals for environmental planning, and infrastructure siting and operations
  • Alternative waste technologies assessment, selection, concept, design, feasibility and options

Gold Coast City Council Waste Network Review

image

Since 2003, GHD assisted Gold Coast City Council to strategically review waste infrastructure provided by the city. This primarily includes landfills and transfer stations as well as a small number of rural bin stations, but has also considered issues associated with kerbside collection services and the concept of user-pay. At the commencement of the project the waste network included five landfills, 11 transfer stations and three rural bin stations servicing a population of approximately 500,000 people.

Initially the project involved a critical review of existing waste infrastructure by taking a triple bottom line approach, i.e. considering economic, environmental and social factors. The outcome of this assessment, prepared in conjunction with council officers, was a timeline for rationalisation and upgrades to the network. From this timeline, a year-by-year budget estimate was developed  based on individual recommendations and capital and operating costs.

Huntingdon Wastewater Treatment Facility Improvements, Smithfield Township, Huntington County, Pennsylvania, USA

image

GHD’s innovative approach to improving this wastewater treatment facility earned the Diamond Honor Award (Water and Storm Water Category) for innovation and excellence in engineering from the American Council of Engineering Companies of Pennsylvania in February 2013.

The Huntingdon Wastewater Treatment Facility, constructed in 1964 and upgraded in 1987, was in the first group of facilities required to comply with the Pennsylvania DEP’s Chesapeake Bay Tributary Strategy (CBTS). GHD was challenged to meet CBTS requirements using existing, simple-to-operate trickling filters and to provide Class A exceptional quality biosolids within the existing site footprint, while maintaining uninterrupted service during construction.

Integrated Solid Waste Management Planning, Delaware County, New York USA

image

As part of Delaware County’s goal to continue to utilize their existing landfill site, they embarked on extensive efforts to re-define their solid waste management goals and objectives. In order to do so the County assembled a team of planning specialists who focused on centralised and integrated solid waste management and watershed planning issues.

As part of the overall strategy to fully utilise the existing landfill property, GHD successfully identified a solution to continue development of solid waste disposal and processing facilities at the County’s Solid Waste Management Center that satisfied environmental, regulatory, and watershed management standards. These efforts included: solid waste management planning; development of aggressive recycling and landfill diversion strategies; integration of multiple town transfer stations; biosolids management; wetlands evaluation; landfill siting study and permitting; landfill design and construction services; and municipal solid waste (MSW) co-composting facility development.

Main Success

image

GHD has assisted the Melbourne Water Corporation to replace a section of its oldest sewer network, first built around 1894. The existing main, which had significantly deteriorated, needed to be replaced to continue providing essential services to the city’s growing inner north population, and reduce the risk of failure associated with ageing infrastructure.

As principal consultant, GHD provided design management, structural and civil design, geotechnical and hydrogeological analysis, durability assessments, tunnel lining design, hydraulic capacity analysis, planning and statutory approvals, environmental investigations and management, odour control design, preparation of contract documentation and construction phase services.

Orange Waste Project

GHD was engaged to prepare an environmental assessment (EA) to assist with the development of a new resource recovery plan and transfer facility as well as new composting and landfilling operations in the New South Wales district of Orange. The project is an integrated resource recovery and waste management scheme that promises to be a model for sustainable regional waste management. Our team also designed one of Australia's first baled waste land fills for their Euchareena Road site.

Working with Orange City Council and a range of groups providing inputs, our team coordinated and prepared the EA document as well as prepared concept designs for the landfill and enclosed tunnel composting facility at Euchareena Road Resource Recovery Centre to support the application.

North Stradbroke Island Landfill Closure

image

GHD was engaged by Redland Shire Council to prepare the design and documentation for the closure and capping of the North Stradbroke Island landfill. The landfill is situated off the main road between Dunwich and Point Lookout in bushland.

The design was not straightforward as North Stradbroke Island is predominantly a sand island. Alternatives had to be found to replace the standard clay cap. In addition the landfill included various pits and mounds around the site.
