		A free-water surface CW as it is aesthetically pleasing
		A horizontal subsurface flow CW since its dimensions would be smaller than any of the other types of wetlands that were discussed in the course.
		A vertical flow CW since it will recover more water than the free-water surface or the HSF CW, and its footprint would be smaller than the other two.
		Wetlands should only be used for larger areas, such as neighborhoods and villages, and not in households
