Over the last five years, Philadelphia’s Green City, Clean Waters Program, the first green-centric plan in the U.S. to deal with stormwater and combined sewer overflow pollution, kept 600 million gallons of polluted water from reaching nearby rivers.
This June will mark the fifth anniversary of the program. Over the last five years, the Program developed procedures for designing and building rain gardens and street tree trenches that use plants, soil and stone to capture, slow and filter the water that falls on streets and buildings during storms.
Coming into 2016, the Program created over 750 acres of green infrastructure to handle these sources of water pollution.
The Philadelphia Water Department, which oversees the Green City, Clean Waters Program, is asking residents to complete a 5-minute online survey by March 28 to help the agency understand the public’s knowledge and perspective on green stormwater infrastructure.
