The Philadelphia Water Department has signed Green Cities, Clean Water, an agreement to expand the city’s green infrastructure significantly during the next 25 years. The main goal is to reduce combined sewer overflows (CSOs), but the city has quantified other benefits such as park visits, ecosystem services, green jobs, and increased quality of life. The project will transform one-third of impervious areas served by Philadelphia’s combined sewer system, and projections estimate that green infrastructure will prevent the release of 80% of CSOs. Also, check out the Green Cities, Clean Water video.
