The use of wetlands as a wastewater treatment technique: a literature review

As the database of information for constructed wetlands grows, the benefits and limitations of this alternate wastewater treatment technology will be better understood. Based upon the results for numerous field and case studies, wetlands treatment can be highly successful at a relatively low cost. This technology appears to hold considerable promise for its technological capabilities plus it is widely applicable. Wetlands treatment has been successfully used to treat domestic wastewater, industrial wastewater, leachate, acid mine drainage and stormwater.
