Stormwater Grants

Enhance your property.
Reduce your monthly bill.
Clean up Philadelphia’s waterways.

Stormwater grants can cover up to 100% of the cost to design and construct stormwater retrofit projects on non-residential properties in Philadelphia. Stormwater retrofit projects provide an opportunity to add new landscaping, fix drainage problems, and improve the appearance of a property. After a project is complete, the property owner qualifies for lower stormwater charges on his or her monthly bill.

These stormwater retrofit projects are a cost-effective way for the Philadelphia Water Department (PWD) to reduce stormwater pollution in Philadelphia’s creeks and rivers. PWD partners with the Philadelphia Industrial Development Corporation (PIDC) to award more than $15 million in stormwater grants every year.

Project Models

Anyone can apply for a stormwater grant with permission from the property owner. When a project is awarded a grant, the applicant is responsible for signing an agreement with PIDC and handling the administration of the grant.

PWD offers three options for interested applicants to receive a stormwater grant:

  • Standard SMIP: the property owner or tenant applies for and manages the grant
  • Alternative SMIP: a community group, non-profit organization, or vendor applies for and manages the grant
  • GARP: a vendor bundles multiple properties into a single application
