Floating Constructed Wetlands (FCW)

Floating Constructed Wetlands (FCWs) are one of the non-traditional tools being considered by the Town of Orleans to manage nitrogen within the Town’s coastal embayments. FCWs are man-made rafts that float on the water’s surface and are planted with native plants. Under appropriate conditions, it has been shown that as water passes through the FCW, plant roots, bacterial activity and chemical/physical processes can reduce nitrogen levels as well as phosphorus, biological oxygen demand, total suspended solids and fecal coliform.
