− | Forebays are a form of pretreatment for open inlets. By dissipating the energy of incoming flow and causing suspended particles to drop from the water. This sediment can then be easily swept or vacuumed during routine maintenance and doesn't end up clogging downstream biomedia or filter material. A well designed forebay will also spread the flow somewhat, reducing erosion around the inlet.</p> | + | Forebays are a form of pretreatment for open inlets.
