Lead Organization: Philadelphia Water Department
Green City, Clean Waters
In 2011, Philadelphia adopted a green infrastructure plan to reduce stormwater pollution entering their combined sewer system called Green City, Clean Waters. By employing green tools instead of just relying on traditional infrastructure like pipes and storage basins, Philadelphia will meet standards set by the Clean Water Act while saving an estimated $5.6 billion over 25 years. To learn more about the details of their plan, and to find great examples of green infrastructure projects on small and large scales, check out their website. You can also check out a map of all of their current projects here.
