Garbage Water

The annual amount of debris collected by waterway trash racks in an average city varies widely, influenced by factors such as population size, urban development, and local environmental conditions.​​ ​​While specific data for an "average" city is scarce, some municipalities have reported significant figures.​​

For instance, the City of Los Angeles captures approximately 4,000 tons of debris annually through its storm drain system, which includes trash racks and other capture devices.​​ ​​

Similarly, the City of Baltimore's Inner Harbor Water Wheel, a trash collection device, removes about 200 tons of debris each year.​​ ​
