Egniol has been providing engineering and environmental services in relation to landfill site closure works at a former tin and copper mine in the south west of England since 2007. The site has been undergoing progressive completion and restoration work in readiness for handback to the Local Authority in accordance with the permit and planning requirements. The work has been wide ranging and covered most aspects of the engineering of former landfills prior to return to beneficial use.
In particular we have provided design and construction supervision services for the capping system construction; preparation of a Site Restoration Plant for the use of soil forming waste materials as a waste recovery operation; the creation of a wide range of ecological habitats to form heathland, native woodland, glades and acid and native grassland and integration into a fully functioning ecosystem; design and construction supervision of the surface water management system; design and construction supervision of the burial of approximately 18 kilometres of active landfill gas pipework and lowering of associated infrastructure such as gas manifolds and condensate de-watering points; the re-establishment of a 1.3-kilometre public bridleway across areas of the historical tin and copper mine and the landfill containment cells. Egniol designed and managed the construction of the bridleway following discussions with the Rights of Way officer, Mining Consultants and the British Horse Society.
Our work at this challenging site is ongoing and we continue to bring our experience and expertise to bear in the restoration of this site.
