Subsurface flow constructed wetlands are in relatively common use in Europe, Australia, and in a number of states in the United States. However, there has been no apparent consensus on design procedures or performance expectations. A two-step procedure was used for the preparation of this report to develop a consensus among knowledgeable experts.en-USwastewater managementconstructed wetlandsenvironmental protectionTechnical Report
