The second phase of Detroit's Milliken State Park includes a wetlands demonstration area that showcases nature's water filtration.
Collected stormwater passes through a swirl separator to remove suspended solids, oil and grease. The stormwater is then pumped into a four-foot deep sediment forebay, which allows additional sediment to drop out before entering three-foot deep pools with emergent plants. Finally, the water passes through 18-inch deep braided wetland streams to increase vegetation and stormwater interaction for maximum filtering, before passing over a weir and entering the river.
