Philadelphia's Radical Green Infrastructure Plan Will Harness Rainwater, Fight Pollution (Video)
"Green infrastructure" is a collective term for smarter practices on land that stop water pollution, like green roofs, porous pavement, roadside plantings and increased park space. These methods stop rain where it falls, allowing it to filter back into the ground. That keeps it from turning into runoff that carries pollution, like oil and gas products, trash, and pet waste, from paved surfaces into the water ... This all makes for not only cleaner waterways, but also, as Philadelphia recognizes, all-around healthier, more pleasant places to live. By accounting for a range of social, economic, and environmental benefits that come from adding green spaces to city neighborhoods, Philadelphia has projected that a green approach to reducing sewer overflows will yield more than two dollars in benefits for every dollar invested!
