The elements of landscape-based water treatment design are reviewed in this work. The paper examines the most commonly utilized elements, such as Vegetated swale/Bio-swale and Constructed wetland, as well as their benefits and possibilities for treating water for various purposes, such as irrigation and domestic usage. This paper also reviews the literature on determining the potential of plants used for pollution removal, particularly the capacity of Vetiver grass to remove pollutants from waste water.
