The amazing machine you see before you uses a combination of old and new technology to harness the power of water and sunlight to pick up litter and debris flowing down the Jones Falls stream.

How Does Mr. Trash Wheel Work?
➊ The current of the river carries trash that is collected by the trash booms.
➋ The raking system lifts trash and debris from the water and deposits it on the conveyor belt.
➌ The conveyor belt deposits trash into a dumpster floating on a separate barge.
➍ The current of the river provides power to turn the water wheel that runs the conveyor belt.
➎ When the dumpster is full, it is towed away by boat and a new dumpster is put in place.
➏ Solar panels provide additional power to keep the machine running even when there is not enough water current.
➐ The sail fabric cover protects the trash monitoring equipment and the dumpster barge.
➑ Googly eyes make everyone love Mr. Trash Wheel.

Where Does the Trash Come From?
When it rains, water carries litter off streets and into storm drains, which flow unfiltered into neighborhood streams.
