Green City, Clean Waters

Green City, Clean Waters and Stormwater Regulations

Implemented in 2011, Green City, Clean Waters represents an agreement between Philadelphia, the U.S. Environmental Protection Agency and the Pennsylvania Department of Environmental Protection to meet Federal water pollution standards set by the Clean Water Act. The plan relies on green stormwater infrastructure to reduce the volume of polluted stormwater runoff entering our sewer system and waterways by 85 percent by 2036. The private development sector acts as a key driver of the Green City, Clean Waters plan and has implemented hundreds of green infrastructure projects since 2011. The Philadelphia Water Department’s Stormwater Regulations are designed to provide the development community with incentives to bolster Philadelphia’s green stormwater infrastructure and strengthen the Green City, Clean Waters plan.
