Kerdiffstown Park Project

Kerdiffstown Park Project involves the remediation of the former landfill site at Kerdiffstown, Naas, Co. Kildare. The site is currently closed in a disused state and poses a long term risk to human health and the environment due to pollution by landfill gases, odour and leachate. RPS intend to remediate the site and provide a multi-use public park including playing pitches, playground and facilities.

Challenge

The project involves many challenging aspects including:

  • Adherence to the conditions of Industrial Emissions Licence P1063-01 for the site as issued by the Environmental Protection Agency in Ireland.
  • Adherence to the conditions of the planning permission granted by An Bord Pleanála and the Schedule of Commitments from the Environmental Impact Assessment Report.
  • Reprofiling the waste body across the site to achieve the required side slopes and surfaces for landfill capping works. The capping system includes 1mm LLDPE with geotextile drainage layers.
  • Management of emissions during the remediation phase that includes odour, landfill gas, leachate, groundwater and surface water management systems.
  • Demolition of a significant number of reinforced concrete structures across the site while adhering to noise and vibration measures.
  • Installation of wastewater and leachate transfer pipelines from the site to the nearest wastewater pumping station. This includes directional drilling under a live dual carriageway (N7) and the Morell River.

Solution

The site occupies approximately 30 hectares and the works include: reprofiling and shaping the waste body; demolition and site clearance; installation of an engineered capping system across the site; installation of new environmental management and control systems including leachate and landfill gas. This will enable the development of a public park with multi-use sports pitches, car parking, changing room building, children’s playground and a network of paths across the site including provision of services and foul drainage to the public sewer network.
