To arrest the negative impacts of nonpoint source pollution, the Milwaukee Metropolitan Sewerage District seeks to innovate a subsurface gravel wetland that holds rainwater where it falls, infiltrates and filters it, absorbs it through plant root systems, and evapotranspires it to the atmosphere. Through this project, the Sewerage District will implement this innovative infrastructure measure in the Green Tree Basin on Lincoln Creek, a tributary of the Milwaukee River, to address six beneficial use impairments in the Milwaukee Estuary Area of Concern.
