What is Small Scale Constructed Wetland Treatment Systems: Feasibility, Design Criteria And O&m Requirements (werf Reports) about?

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. Information on 1,789 existing small-scale wetland treatment systems in 19 countries was collected. This data indicates that 81% of small-scale constructed wetlands use subsurface flow. The median size range for free water surface (FWS) wetlands was 389 m^3/day (103,000 gpd), while for vegetated submerged bed (VSB) wetlands it was only 2.6 m^3/day (687 gpd). 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 ap
