Jameson Road Landfill

Jameson 1

The Jameson Road facility is a major regional landfill in Lancashire, UK accepting a range of MSW, Industrial and Commercial wastes. It was formerly a local council operated site, now owned and operated by multinational utility company SUEZ. For the past 20 years the Byrne Looby team have provided comprehensive multidisciplinary construction support, master planning, design and permitting advice on this site to SUEZ. The site initially required extensive remedial works to bring it up to modern standards, including the design and installation of over 40 hectares of capping and isolating the older part of the site with a major engineered separation bund. Over 20 years the remaining area of the site was progressively developed with new engineered containment cells, constructed to the standards required by the EU Landfill and Groundwater Directives. Extensive landfill gas and leachate management systems have been installed.

Our Role

We initially project managed the remediation of the former council operated part of the site, designing and supervising an 800,000 m3 translocation of wastes, construction of a 1 km long engineered separation bund and installation of 40 hectares of geosynthetic capping.

For over two decades have periodically designed, supervised and verified the construction of multiple new landfill cells and associate capping works as landfilling has progressed across the remaining 60 hectares of the site.

The landfill is lined with a composite mineral clay / HPDE liner and capped with an LLDPE geomembrane.

For each new, separate cell construction and post infill capping contract we have assisted the operator to procure the contract and supervised the works. This starts with the detailed design, securing approval from the regulator (UK Environment Agency), preparing the contract specification and issuing the tender pack to contactors. We then supported our client through the tender evaluation process, contractor appointment, management of the contract works and by providing site-based supervision of the works. On completion of the works, we provided the regulator with the necessary CQA verification reports.
