Landfill Leachate Treatment at BobbingworthNew, existing or former landfill sites all have the potential to pose significant threats to rivers and groundwater.

Leachates such as those from Tips, composting and silage facilities are produced as they are open to the elements and rainfall will permeate through the layers of waste. This, combined with the resulting liquid from the decomposition process, produces leachates that have the potential to contaminate land and surface or ground waters around the area.

This type of leachate is difficult to treat as its composition can vary from site to site.  Factors such as the age of the site, type of waste, size of the area and treatment already in operation, can all impact on its composition.

In addition to landfill leachate, many waste management facilities are now facing the additional challenge of treating run-off from composting and recycling facilities which can be extremely potent and will require treatment before discharge.

Reed bed treatment systems provide a sustainable and cost-comparable way of preventing groundwater contamination which is both low-energy and low-maintenance.
