A constructed wetland is an artificial ecosystem growing in a shallow basin, with plants suited to a swampy environment (hydrophytic plants).

The purpose of the constructed wetland is to deal with a wastewater stream, such as partially treated sewage or contaminated runoff.

When used in the final stages of wastewater treatment, their role can be described as "polishing" (raising the water quality from fairly clean to very clean). In greywater reuse, a constructed wetland is sometimes used for treatment.

An overlapping term is reed beds, which might be considered a synonym, or a specific type of constructed wetland.[verification needed]

Mosquito control should be considered as part of the design. In a balanced ecosystem, there will be predators (such as certain types of fish) to eat the mosquito larvae.
