Many Philadelphians are keen to help and will travel across our city to lend a hand, but it's not always easy to know how. Register on this site and add your event to the community calendar.

The City of Philadelphia provides several services to assist local community groups in organizing cleanups. In particular, they will lend equipment (Shovels, rakes, etc.) and will provide a pickup service for any litter and garbage your team collected.

Once you have your cleanup planned you can request resources online here.
Outside of the City resources, the State also has support programs for community cleanups - see Pick Up PA as an example.
