If one way be better than another, that you may be sure is nature’s way.

Signicant work for development, implementation, and operation of constructed wetland systems (CWSs) has been performed in the last 20 years, resulting in their broad and increasing application: In 1996 more than 20,000 constructed wetland systems
were operated worldwide, while recently (2011) their number is estimated to exceed 50,000 [62].
