Small-Scale Constructed Wetland Wastewater Treatment Systems Feasibility, Design Criteria, and O&M Requirements

The use of constructed wetlands for treatment of domestic wastewater has increased significantly in the past decade, especially for small-scale applications. Unfortunately, there is no central source of information on small-scale wetland systems. This study provides guidance for designers and operators of small-scale wetland systems and discusses the feasibility of constructed wetland technology. It identifies wetland technologies that are appropriate for small-scale treatment systems and evaluates the use, distribution, and performance. The report contains information on wetland plant selection and establishment, operations and maintenance, cost; and ends with a discussion on special applications of wetland technology. The researchers provide guidance on the two most crucial aspects of small-scale wetland design: hydraulics and pollutant removal. Published by WERF. 304 pages. Soft cover and online PDF.
