The Green City, Clean Waters Program is Philadelphia’s 25-year plan for the control of combined sewer overflows. The key to the program is a block-by-block approach in which each project is essentially treated like a pilot – monitored and tested at every turn to determine how it’s working. This is the largest such program ever envisioned in the U.S. with a total investment of approximately $2.4 billion dollars.
The program is broken into three fronts: water, land, and infrastructure. For the water aspects of the program, our team develops restoration and stabilization designs for tributaries and main stem streams. An example is Tacony Creek, we improved 3.2 miles of streamline and surrounding wetlands.
We are also involved in three land-based programs: Green Streets, Green Schools, and Green Parks. A variety of practices, such as stormwater bumpouts, rain gardens, infiltration basins, tree trenches, porous pavement, and swales, are used to provide pollutant filtration while reducing the volume of stormwater discharges to the public sewer network.
Traditional infrastructure is sometimes more appropriate. In these cases, our team provides assessment and design of water and sewer upgrades and replacement projects.
