     “The Philadelphia Water Department (PWD)’s Green City, Clean Waters program is recognized at an international scale for its ambitious goals and innovative strategies to treat and manage storm water in Philadelphia. The program is redefining the way people think about their infrastructure and helping to improve the urban landscape of the city. A once highly impervious environment is being transformed through the implementation of green storm water infrastructure (GSI). This technology takes advantage of urban fabric to incorporate vegetated, “green” landscapes to slow, filter, and manage rainfall to prevent polluted runoff from entering our sewers and waterways. GSI can be implemented into Philadelphia’s streets, sidewalks, roofs, schools, parks, parking

lots and more.”
