Reduce Your Stormwater Fees

The City of Philadelphia offers a number of programs to assist non-residential customers to reduce their stormwater fees by managing the runoff from their property.

How Do Stormwater Rates Work?

  • Stormwater runoff contains contaminants such as motor oil, pesticides, automotive fuel, industrial waste and other chemicals that pollute streams and rivers.
  • Every parcel of land in the city, including residential, commercial, institutional and public properties, is billed by the Philadelphia Water Department for management of the stormwater it produces.
  • Philadelphia stormwater fees calculated based on the amount of impervious surface (such as parking lots, sidewalks, driveways and buildings) that a parcel contains.
  • Parcels with greater amounts of impervious surface produce larger amounts of stormwater, and as such are charged higher rates for stormwater management.

How Can I Reduce My Stormwater Rates?

  • Non-residential customers, including businesses, institutions, non-profits and public agencies, can reduce their stormwater rates and help clean up our waterways by implementing green infrastructure projects.
  • Green infrastructure projects include: Rain Gardens, Green Roofs, Basins and Ponds, Wetlands, Swales, Underground Projects, Downspout Planters, Rainwater Harvesting, Porous Pavement and Reducing Impervious Surfaces.
  • Projects that reduce the amount of impervious surface on a site can result in a stormwater credit that will permanently reduce your water bill.
  • Technical assistance in developing stormwater management projects is available through the Green Guide For Property Management.
  • Philadelphia Water Department and the Philadelphia Industrial Development Corporation offer the Stormwater Management Incentives Program. The SMIP Grant will provide financial assistant to non-residential property owners who desire to build green stormwater infrastructure to manage private property runoff.
