Funders and Sponsors

The work of the GSI Partners is supported by generous grants from the Surdna Foundation and the William Penn Foundation. Our work aligns with their goals of watershed protection, strong local economies, thriving communities, and the many other triple bottom line benefits of green stormwater infrastructure.

We also value support from our annual sponsors.

If your company is interested in sponsorship of the GSI Partners, contact Anna Shipp at anna@sbnphiladelphia.org.
