Stormwater Grants

The Philadelphia Water Department offers incentives to property owners, project managers, and developers to keep and increase stormwater management on their property for lower costs.

What is the Stormwater Grants Program?

Stormwater Grants can pay for the design and construction of 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 their monthly bill through the Stormwater Credits Program.

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 millions in stormwater grants every year. The Stormwater Grants Application Guide is a critical resource for learning more about how to apply for a Stormwater Grant.

Stormwater Grants and resulting stormwater credits lower a property owner’s monthly stormwater bill. To learn more about how stormwater bills are calculated or to address a bill you think is incorrect, visit the Stormwater Billing page →

The Stormwater Grants Program is one type of Stormwater Incentive offered by the Philadelphia Water Department and managed by the Stormwater Incentives team. Learn about other types of Stormwater Incentives →
