Diverse vegetation is also resilient and adapts to changes in land-use and variation in weather conditions. The extent of the services that wetlands provide to people depend on wetland design and well-being, as well as on land-use within the contributing watershed and weather dependent pollutant loads. Constructed wetlands typically consist of a flow dissipating and heavy sediment settling inlet pond, a vast shallow emergent plant covered wetland, and a sediment settling outlet pond. The Säynäslanhdenpuro Wetland consists of three parallel research wetlands with flow and pollutant load monitoring facilitating outlet dams.

A stormwater wetland is a constructed transitional landscape between water and dry land. Wetlands are natural water detention and purification landscapes. Constructed wetlands are thus established to compensate for challenges to water environment brought about by land-use change. Urban wetlands dissipate and detain runoff thereby preventing flooding and drought extremes. Water quality is mitigated through sediment settling, and purification of soluble pollutants by wetland plants, microbes and soils. Diversity of plants and their associated microbes is a key element in purifying urban waters.
