It accepts 600,000 tonnes of municipal solid waste per annum and is Ireland’s only baled waste landfill.  FT has acted as designers in the Design Build Partnership with Roadbridge Ltd since development commenced in 1996.

FT was initially appointed by South Dublin County Council to design and supervise the remediation works of an unauthorised waste disposal area at the site.  This work was carried out in 1996, and included the placement of 45,000m² of landfill capping and the construction of a “cut-off” wall comprising bentonite-cement slurry with a maximum hydraulic conductivity of 1 x 10-9m/s (600mm wide x 20m deep x 970m long).

Subsequent to this, the development of a fully engineered, EU Landfill Directive compliant non-hazardous landfill has been carried out under a design-build contract, with Roadbridge Ltd as Contractor, and FT as the Designer.  Under this contract, FT has designed and supervised the construction of over 200,000m² of fully engineered landfill lining, constructed on a phased basis, with a total waste disposal void of over 4.8 million tonnes of waste.

FT has designed and supervised the phased restoration of the facility, comprising capping (in accordance with the EU Landfill Directive) of over 235,000m², in eight phases from 2002-2013.  The restoration design included the following elements: landscape plan, vegetation, soil layers, drainage layer, impermeable barrier layer, leachate re-circulation system, gas collection & control systems, surface water management, and stability Assessment

In addition to the above services, FT have provided the following services:

  • Design of the leachate collection system and sequencing batch reactor (SBR) treatment plant upgrade including all civil, M&E and SCADA works to double its capacity to treat up to 300 m³/day
  • Detailed review of gas treatment capacity for South Dublin County Council, including the calibration of the gas prediction model (GasSIM) for site specific conditions and assessment of the requirement in terms of landfill gas flares and engines for the future
  • Preparation and submission of a planning application and Environmental Impact Statement for extension of time for facility operation
  • Extensive operational support, including:
    • onsite management of landfill gas systems
    • monitoring and reporting of environmental data
    • compliance with Waste Licence conditions
    • preparation and submission of landscaping plans for the site.

FT has been the designer for all landfill development works at the facility (two phases constructed to date, with a combined void of over 400,000m³).  Our duties included:

  • Preparation of waste licence compliance reports for submission to the Environmental Protection Agency (IRE)
  • Procurement and supervision of site investigation works
  • Design, specification and onsite construction supervision of:
    • Site access road
    • Landfill cells
    • Leachate management system and treatment plant
    • Landfill gas management
    • Stormwater management including flood attenuation
    • Administration building

  • Contract administration (i.e. attendances at client review and site meetings and provision of construction support to the Contractors)
  • Provision of Resident Engineer (on-site supervision) services for the execution of the works.

 

FT prepared contract documents for the installation of a twin line gas collection system which allows gas to be sent either to the ‘high quality’ or ‘poor quality’ gas lines, dependant on methane content.  High quality gas may ultimately be utilised for energy generation, while the poor quality gas is sent to the flare, via a carbon filter for combustion to neutralise odours and minimise the emission of greenhouse gases from the site.

Since our appointment FT has provided extensive operational support including:

  • Void capacity analyses for all phases of the development
  • Detailed review of traffic management and routing options within the site
  • Planning of waste placement activities
  • Selection and analysis of daily cover material
  • Analysis of historical surface water & groundwater data & establishment of trigger levels for emissions
  • Ecological monitoring services including badger sett inspections, bat box visits/maintenance, and night-time bat surveys
  • Investigation of naturally occurring levels of methane and carbon dioxide and impact assessment
  • Baseline Biological Assessment of watercourses within the site boundary and submission of report to the EPA
  • Preparation of Emergency Response Procedures
  • Preparation of Waste Recovery Reports
  • Development of an Environmental Management System for the site
  • Noise modelling
  • Odour management
  • Preparation of Environmental Liabilities Risk Assessment and Closure Restoration and Aftercare Management Plan for the site.

PowerstownExtension of Powerstown Landfill, Carlow, Ireland

Client: Carlow County Council

Location: Carlow, Ireland

Capital Value: c. €13 million

Key Facts: Statutory consent applications, detail design, procurement and contract management of four engineered cells on a vulnerable aquifer.

The landfill was situated on a regionally important aquifer and so required a landfill lining system higher than that set for non-hazardous landfills.  The lining system proposed by FT comprised of a protective geotextile 2.5mm HDPE on a leak detection geocomposite on 2.5mm HDPE on 0.5m of bentonite enhanced soil (BES) at a hydraulic conductivity on 5 x 10-11m/s.  The BES material was batched on site, using site won material.  The geotextile was overlain by a leachate drainage stone layer (0.5m layer, with hydraulic conductivity of 1 x 10-3m/s).  FT specified a non-calcareous stone to be used in the drainage layer, to mitigate the potential impacts of ion exchange between the sodium in the BES and the calcium which may be precipitated from the drainage stone.

FT’s design included a number of assessments of alternative lining technologies and make-ups; and assessment of the equivalent hydraulic conductivities and leakage rates from each alternative.  FT liaised with the Environmental Protection Agency (IRE) on the assessment of the alternative technologies and final approval of the proposed system which was encompassed into a waste licence review application for the site.

Once statutory consent had been secured (including planning), FT provided detailed design, specification, procurement, and contract supervision services for the construction of new landfill cells and capping of the existing cells.  The following services were provided by FT:

  • Preparation of Specified Engineering Works reports for submission to the regulatory authority
  • Detailed design for each element of the project, including civil, mechanical and electrical design
  • Preparation of tender documents for both civil and mechanical and electrical contracts
  • Management of tendering process
  • Tender assessment and recommendation
  • Construction support and project management
  • Preparation of Construction Quality Assurance reports
  • Contract Administration
  • Preparation of final account report.

In addition to the above services, FT provided the following additional supports to Carlow County Council:

  • Preparation of an Environmental Impact Statement and application for an extension of time for continued operation of the site
  • Preparation of a safety statement and operational Health and Safety Plan for the facility
  • Supervision of the refurbishment of the administration building at the site
  • Ongoing Waste Licence compliance support and environmental monitoring.
