Reclamation of the Westfeld Landfill, Wackersdorf

Brown coal was mined a long time ago on the site of the Westfeld landfill, and later ash, overburden, and filter residues were stored there. The reclamation of the Westfeld landfill essentially pursues 2 goals: On the one hand, the sealing of the landfill so that no rainwater seeps through the deposits and any effects on the groundwater can be avoided; on the other hand, to create valuable habitats for animals and plants on the 80-hectare area.

The centerpiece in construction phase 2 was the pump sump to be built, which serves as a basin and extraction point for groundwater and seepage water. Furthermore, 230,000 tons of soil masses were delivered and introduced in the form of different layers, such as compensation layer, mineral protection layer, root barrier layer, vegetation layer. The other elements of the seal consist of geosynthetic clay liners, nonwovens, and KDB.
