A blog about Landfill Construction Quality Assurance
Current landfill site practice in response to the requirements of the Waste Regulations (UK) is to minimise leachate generation. To achieve this the operator fills the site, in a series of phases or cells which are raised as rapidly as input rates will allow to the top of the landfill, within small constrained areas, to [...]
The use of a Geosynthetic Clay Liner (GCL) as the low permeability layer in landfill lining systems and restoration caps can provide a cost effective and readily Construction Quality Controlled alternative to natural clay. In fact this material may be the only option in regions where the local geology is such that no clay of [...]
In the design of municipal landfill leachate collection systems, some state regulatory agencies require carbonate content of leachate collection system aggregate not to exceed 15 percent by weight. This requirement comes from a legitimate concern about the possibility of aggregate degradation, or loss of mass due to contact with leachate. Most involved in landfill design [...]
New MC3000 rolled out Magpie Drilling has continued its expansion with a further MC3000 added to the drilling rig fleet. Following the increase in customer demand for deeper, larger diameter wells, with temporary and permanent steel casings, the need for increased power, higher torque, and superior depth capabilities are paramount. The new machine has an [...]
Leading drilling specialist Magpie has announced the deepest boreholes/wells for leachate extraction drilled to date. SITA UK approached Magpie with a need for one of the most challenging landfill drilling projects undertaken to date. Enderby Warren a closed landfill site in Leicestershire has existing leachate extraction chambers 74m deep. SITA wanted to retro drill some chambers [...]
