Case Story:

Nature cleans wastewater

The Boliden Tara mine in Ireland was one of the first in the world to successfully demonstrate the potential to remove heavy metals while simultaneously reducing sulfate and nitrogen concentrations through an Integrated Constructed Wetland (or ICW).

“ICW’s mimic natural wetlands but in a confined, monitored and controlled setting,” says Ailish ­McCabe, Environmental Engineer at Boliden Tara. The processes require little or no chemicals and very little maintenance. The pilot scale project has been running for two and a half years.

Constructed wetlands can do more than provide effective water treatment. Over time the ICW develops and the environment provides the ideal conditions, attracting a variety of new species and the area becomes a self-sustaining, biodiverse habitat. Another area attracting a lot of interest is the ability of wetland to potentially sequester carbon and become a carbon sink.
