Installation of the BaySaver The installation of the BaySaver became necessary due to the oils that drip off of the UVA busses while they are not in operation. During rain events, the oil would be washed from the bus parking area into the storm sewer, which leads directly to Meadow Creek. Despite drip pans being used under the busses in an attempt to collect fluids for proper disposal, contaminants were still reaching the stream from the facility. The BaySaver treats the runoff from the bus parking area and filters out contaminants such as oil, sediment, and other pollutants. The BaySaver is comprised of two manholes, a primary manhole and a storage manhole. The primary manhole, seen on the right, is attached to the storm drain and serves to collect large sediment. After passing through the primary manhole, the water flows over a weir plate, which regulates flow to the storage manhole. The storage manhole on the left is the secondary treatment device. Oil and floating debris float on the top of the water, while fine sediment settles to the bottom. Clean water is then discharged from the storage manhole to the outfall. The two small pipes connecting the manholes are the inlet and outlet conneting pipes which convey water between the manholes. The large grooved pipe sticking out of the primary mahole is the actual BaySaver unit. The BaySaver controls the flow of water through the manholes. This picture is looking down from the top of the storage manhole. The pipe on the right is the inlet, which brings water from the primary manhole. The pipe on the left takes water from the storage manhole to be discharged to the storm sewer network. "Tee" Pipes in the primary manhole. The "Tee" pipes minimize turbulence during periods of high flow. These pipes also convey treated water from the primary manhole to the storm sewer system. Construction workers hook the BaySaver up to the storm sewer system. The completed BaySaver system is hooked up to the storm sewer network.
