Managing Storm Waters to Ensure Clean Water:
Nine Mile Run Watershed Association
Through citizen engagement, demonstration projects, and advocacy, Nine Mile Run Watershed Association (NMRWA) restores and protects the Nine Mile Run Watershed, which includes all of Regent Square, as well as parts of Wilkinsburg, Swissvale, Edgewood, and Pittsburgh. The organization’s “green infrastructure” strategy employs rain barrels and rain gardens, pervious pavement, bioswales, green roofs, tree planting, and man-made wetlands to reduce and capture runoff—from impervious roads, sidewalks, and roofs—that causes the stream to rise quickly during storms. With previous support from the Foundation, NMRWA expanded its education and outreach programs, assisted municipalities in adopting plans and ordinances to better manage storm water, and implemented projects to capture and reduce storm water flows, as well as improve water quality. Its multifaceted efforts are minimizing detrimental effects of storm water and combined sewage overflow.
A two-year Foundation grant of $375,000 will support NMRWA’s ongoing education and outreach efforts with residents, students, municipal officials, and regulators; continued watershed monitoring and restoration initiatives; and, as appropriate, collaboration with groups working in other nearby watersheds to help eliminate sewage overflow to Pittsburgh and Allegheny County rivers and streams.
