In 2015, the City of Franklin completed an addition to the City’s Water and Wastewater Operations and Maintenance Facility at 5550 West Airways Drive in the City’s Business Park. Utilizing a grant from the Milwaukee Metropolitan Sewerage District, the City installed Green Infrastructure (GI) elements to manage storm water. These GI elements include two biofiltration basins and two porous paver parking areas.
The biofiltration basins consist of native plants that help to retain rainwater runoff and remove impurities. As the water filters through the subgrade materials, impurities are removed and the volume of water entering the storm drainage system is reduced.
The porous paver parking areas prevent rainwater from running into the street. Each parking area has an underground stone reservoir that allows for groundwater to recharge. The porous paver system provides the structural support of conventional pavement.
