The expanding use of decentralized wastewater management has resulted in an increased interest in small-scale wetland treatment systems. However, there is limited information available on the use, distribution of and performance of these small-scale systems. The purpose of this study was to address this knowledge gap by developing criteria for the feasibility, design, operation, and maintenance of small-scale wetland treatment systems. Monitoring data from the assembled small-scale wetland database was used to develop sizing criteria for FWS and VSB wetlands. Loading rates and corresponding effluent quality were developed for BOD, TSS, TKN, phosphorus, and fecal coliform bacteria. Where there was adequate data, the variation in monthly vs. annual average effluent concentration was assessed to provide a factor-of-safety approach to wetland sizing. Information on internal processes, hydraulic design, operation, maintenance, cost, and industrial applications of constructed wetlands is also presented in this report.

Completely revised and updated, Treatment Wetlands, Second Edition is still the most comprehensive resource available for the planning, design, and operation of wetland treatment systems. The book addresses the design, construction, and operation of wetlands for water pollution control. It presents the best current procedures for sizing these syste

With half of the world’s population now living in urban areas, and rapid urbanization continuing apace, it is essential that the growth of urban areas is supported by the development of adequate and sustainable infrastructure. This work offers comprehensive coverage of critical issues on the highway and urban environment which are key to understanding sustainability in the world's expanding urban areas.

The Malaga Symposia Series provides an international forum for scientific debate on the progress made in research into karst environments. The 2010 meeting of the 4th International ISKA presents 80 papers in four key areas: karst hydrogeology and investigations, karst landscape and ecosystems, human interaction with karst environments, and engineering geology in karst areas. This book will be a useful edition to the libraries of consultants, scientists, lecturers, and policy makers concerned with the special issues of karst terrains.
