It moves slowly, but it has the capability to collect 50,000 pounds of trash. The timing for John Kellett’s creation is crucial — hands and crab nets simply can’t keep up with the growing amount of wrappers, cigarette butts, bottles and other debris carried from storm drains into the harbour. 

“It looks sort of like a cross between a spaceship and a covered wagon and an old mill,” Kellett told. “It’s pretty unique in its look, but it’s also doing a really good job getting this trash out of the water.”
It receives power from the Jones Falls river’s current near the harbour, which turns the wheel and lifts trash from the water into a dumpster barge. Solar panels keep it running when the water current isn’t enough.
The wheel is now docked in the harbor. Each time it runs, it removes an impressive amount of debris. So far, it has 

Healthy Harbor hopes to make the body of water swimmable in less than six years, and the Water Wheel could be a big part of that.“The water wheel has been a time-saver for us,” said Bill Flohr, who runs Baltimore Harbor’s East Marina. “It seems to be collecting probably 95 percent of what we normally had to pick up by hand.”
