Green City, Clean Waters: Philadelphia's Green Stormwater Infrastructure Program

National Planning Excellence Award for Implementation Green City, Clean Waters: Philadelphia's 21st Century Green Stormwater Infrastructure Program Philadelphia, Pennsylvania Hundreds of historic cities like Philadelphia experience combined sewer overflows during heavy rainstorms. Philadelphia Mayor Michael Nutter gave the green light to explore reverting from "gray," or traditional stormwater management infrastructure, to "green" or sustainable infrastructure that mimics the natural water cycle. In 2011, Philadelphia reached an agreement with the Pennsylvania Department of Environmental Protection and the U.S. EPA to explore a largely green stormwater management infrastructure plan to reduce sewage overflows. As a result, an ambitious and comprehensive attempt to overhaul stormwater infrastructure was developed. Green City, Clean Waters (GCCW) has not only made Philadelphia the first city in the U.S. to meet both state and federal water quality mandates through green interventions, but it will also save the city an estimated $6.5 billion in construction costs over building new pipes.
