Leachate Treatment

Leachate must be collected and treated in order to prevent water pollution.

Liners and drains
Every section of the Environmental Centre comprises an underlying liner that collects leachate. The liner system is comprised of a moraine clay layer, a polymer liner and a drainage and protective layer.


Pre-treatment of leachate
The collected leachate from the landfill is transferred to the Environmental Centre's pre-treatment plant. The leachate is pre-treated here so that it corresponds to ordinary urban sewage and is then led to the grid for further treatment at one of the waste water treatment plants.
