The concept of a Waterwheel Powered Trash Interceptor (trash mill) draws its inspiration from the situation present at the Inner Harbor end of the Jones Falls River. Presently runoff carries tons of trash and debris down river to the Inner Harbor. At this location floating trash is prevented from entering the harbor by a boom stretched across the river. City owned trash retrievers and marine operation crews remove this trash as they can within the limitations of equipment and workforce. However, this trash is frequently an eyesore with a negative impact on the perception of the harbor and the city. For many visitors staying at neighboring hotels or parking on the east side of the Inner Harbor this trash is their first impression of Baltimore.
