ABSTRACT
Design of treatment wetlands may be roughly divided into two categories: sizing calculations and physical specifications. Sizing procedures may in turn be predicated on the particular application, whether the purpose is for treatment of flows intended for surface water discharge, or for conditioning water for groundwater discharge, or for retaining and treating stormwater runoff. Further, local regulations may require compliance with specific numerical standards (performancebased) or may simply require certain design specifications according to prescriptive criteria (technology-based).
