The Nine Mile Run Watershed Association is a non-profit charitable organization based in Wilkinsburg which oversees…More the health of the Nine Mile Run River and the surrounding ecosystem. In 2006 there was an aquatic ecosystem restoration of the river which included stream channel reconfiguration, wetland reconstruction, and the planting of native foliage. This was the largest urban stream restoration in the United States at the time.
Today NMRWA seeks to maintain and promote the health of the river, spreading awareness about Pittsburgh's combined sewer/storm drain system and how this contributes to the flooding and pollution of the river and surrounding areas. It is running multiple programs such as the Rain Barrel Initiative where they are installing rain barrels on local homes and helping stem the flood of rain water into the river and encouraging residents to use the water for their lawns and gardens. Other programs include Green Links, Urban EcoStewards, and the Reagent Square Gateway Project.
