About UpstreamPgh

Climate change is having an impact across the globe. Here, in our urban environment, these shifts are felt in our neighborhoods, parks and backyards. This is why we work to combat the effects of it, from managing excessive stormwater flows, to pollutants in our water, soil and air, and to connect each other with the environment to create positive change. From large green infrastructure projects that divert and infiltrate thousands of gallons of stormwater to residential projects that keep basements dry while providing beautiful native landscaping, UpstreamPgh has become the region’s leading resource for water management. Our heritage in Nine Mile Run, coupled with hundreds of projects via StormWorks, provides our community with hands-on, brains-on solutions.

In 2021, to recognize our proactive approach to stormwater problem-solving and its impact across the region, we became UpstreamPgh. Together, we are working to address the environmental problems that are happening in our communities by thinking, speaking and acting upstream. We invite you to join us.

What we do

We work to connect people with nature for a positive impact on the environment. From schoolchildren to municipal leaders, scientists to citizens, volunteers to homeowners, a healthy community starts with education, outreach and engagement.
