The volume of garbage in our rivers, lakes, and oceans has become a global crisis. Stormwater carries litter from roads, parks, and sidewalks into streams where it can break down and harm critical habitats.
Solving the problem will require strategies that are both scalable and simple for communities to implement. Our affordable in-stream trash removal project, making use of technology called the “Litter Gitters,” aims to see how effective the devices are for removing debris from the river.
The Litter Gitter is a small-stream litter collection device designed to catch floating trash from stormwater runoff. It uses floating booms to guide trash into a wire-mesh container which can be emptied after a rainstorm. Initial tests indicate a 80% success rate in intercepting floating litter.
LITTER GITTERS IN PROCTOR CREEK
Atlanta’s Proctor Creek is heavily urbanized and subject to the harmful effects of unmitigated stormwater, illegal dumping, and aging sewer infrastructure. Trash that enters Proctor Creek along its nine-mile stretch eventually finds its way into the Chattahoochee River, where it can interfere with trout and bird populations and pollute our primary source of drinking water.
The Litter Gitter is designed and installed by Osprey Initiative, a company led by owner and founder Don Bates. During his 25-year career in environmental consulting, Bates found himself cleaning the same stream site repeatedly.
Fed up, he built and tested the Litter Gitter with the hope that it could make a dent in the growing litter problem. “We’re getting actual data, not just opinions,” said Don Bates. “This data will tell stakeholders exactly how much and what is collected—useful information for those seeking to reduce trash pollution upstream.”
Data collected from two Proctor Creek Litter Gitters have proved promising. From June to December 2019, the traps collected over 350 pounds of floating trash, with 28% of the total volume able to be recycled. As more pollution data is analyzed, CRK will investigate developing tailored solutions for reducing plastic litter in a given watershed.
We hope that these Litter Gitter trash traps will complement our ongoing volunteer cleanup activities and will help us be more proactive in the fight against trash in our river.

After the traps are installed, the work is far from over. Litter Gitters are emptied after each heavy rain by employees recruited and trained by Groundwork Atlanta, a local nonprofit organization dedicated to nurturing community partnerships that engage local residents to improve quality of life.
As the floating refuse is removed from the trap, a forensic audit is conducted using the U.S. Environmental Protection Agency’s Escaped Trash Assessment Protocols or ETAPs; any recyclable material is separated from vegetation and trash.
With an increasing number of trash traps entering the watershed, there may be opportunities for volunteers to maintain the Litter Gitters and fill out ETAPs. As funding opportunities become available, CRK will develop criteria for choosing future trash trap instillation sites.
