Constructed wetlands

TVA operates the nation’s largest R&D facility dedicated to the science and engineering of constructed-wetland treatment systems. Staff members working at the facility in Muscle Shoals, Alabama, have been pivotal in the evolution of constructed-wetland technologies.

Natural and enhanced biological, chemical, and physical processes are used to remove metals, nutrients, and organic pollutants from aqueous discharges. Constructed-wetland treatment systems that are properly designed and operated require minimal operation and maintenance expenditures to manage diverse types of wastewater discharges, including:

Municipal and domestic wastewater
Acid and alkaline mine drainage
Coal-ash leachate
Coal-pile and refuse runoff
Explosives-contaminated groundwater
Metal-contaminated wastewater
Stormwater
Other agricultural, industrial, and municipal aqueous discharges.

Our patented ReCiprocating constructed-wetland technology (ReCip®) is simple and more cost-effective than other wetland technologies. We’ve developed processes to enhance wetland aeration and can perform unbiased treatability studies and technical evaluations. Our services run the gamut from conceptual design and demonstration to full-scale implementation, and our multidisciplinary team can operate anywhere in the United States or abroad.
