Recycled plastic rain barrels placed underneath large parking lots and buildings would be a huge solution to combating climate change and flooding. In Cleveland, Ohio, parking lots and huge buildings contribute significantly to the water runoff issue. The city space itself is 26% parking lots, which would produce an estimated 34,784.64 ft³/s of water a second. Cleveland is also home to 126 combined sewers and aging sewer infrastructure that continuously combines with clean water during heavy rains. Because of this, masses of human and animal waste, infectious pathogens, bacteria, and chemicals, are running off and polluting Lake Erie. Human and animal health become more at risk with every heavy rain. The solution to this detrimental issue is underground rain barrels. These rain barrels aim to capture and store the runoff water to essentially alleviate stress on the already overwhelmed sewers. By holding water from parking lots and buildings in rain barrels and tanks, the sewer company would be able to effectively clear the sewers of the current rain and treat the water from parking lots and buildings more individually. Rather than overwhelm the sewers, instead combat the issue with an eco-friendly and plausible solution.
