We continue to be in close contact with the team at Biffa regarding the ongoing works at Roxby Landfill. I have been given the latest update on these works, which I have copied below for the convenience of local residents.
Update from Biffa:
"We have completed the installation of approximately 17,000m2 of capping in Phase 12; which comprises welded LLDPE plastic. The surface water lagoons and ditches have been installed over the summer period in readiness for winter.
"A further 40 to 60 gas extraction pin wells and additional 600m of scavenger lines are due to be installed into the newly tipped waste in Phase 12 in September thus enabling the gas extraction system to target multiple levels within the waste mass, therefore increasing the overall gas extraction of Landfill gas and the sustainable generation of electricity for the National Grid.
"Due to differential settlement and silt deposition, leachate wells can sometimes fail or become ineffective across landfill sites. We have identified five wells that would benefit from being replaced. The installation of replacement leachate wells necessitates drilling to the drainage blanket at the base of the landfill to allow effective monitoring and removal of liquid from the bottom of the cells. Our contractors Dragon Drilling have been tasked to retro drill five new wells as they have developed high performance equipment and innovative drilling techniques that ensure such complex projects are carried out safely and successfully. Additional odour control units will be deployed in the vicinity of the drilling rig once we commence; we anticipate that the works will start on the 1st September and it will take 6 weeks to complete."
As ever, I will continue to keep residents posted with further updates on these works.
