Arden-Literature Review of Constructed Wetlands for greywater recycle and reuse

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: August 02, 2025 | Last Modified: 2017-09-18
• Constructed wetlands are a low-tech, low energy water treatment alternative that show potential to adequately treat greywater for nonpotable reuse • Despite providing the necessary physical, chemical and biological removal mechanisms for greywater contaminants, removal dynamics are complex and less predictable than more engineered systems • Pathogen reductions provided by constructed wetlands alone are likely not reliable enough to meet regulatory standards for reuse, particularly in the US • If combined with common disinfection technologies (chlorination, UV) constructed wetlands may be an acceptable, low energy alternative for decentralized, nonpotable reuse. This dataset is associated with the following publication: Arden, S., and C. Ma. Constructed Wetlands for Greywater Recycle and Reuse. SCIENCE OF THE TOTAL ENVIRONMENT. Elsevier BV, AMSTERDAM, NETHERLANDS, 630: 587-599, (2018).
