    GREEN INFRASTRUCTURE & A TALE OF TWO CITIES: “Philadelphia has set an example in storm water management the Chicago area should follow to reduce flooding, make waterways cleaner and give a welcome economic boost to struggling communities,” stated an editorial in the Chicago Sun Times (March 2018)


    “Instead of expanding our infrastructure, we put together a plan to price, value, reuse, recycle, infiltrate, transpire or otherwise manage, every drop of rainwater we could. We started to invent the millions of ways to reduce the amount of rainwater that arrived at our sewer inlets. The goal was to consider rainwater as a commodity and a resource—if it enters a sewer drain it becomes a costly waste product,” explained Howard Neukrug, former Philadelphia Water Commissioner. “There is no single formula for success—and we still don’t know whether ultimately we will succeed.”

And to make this change, the water sector needed to expand its definition of “sustainable” from “a longer lasting concrete treatment structure” to a more universal understanding that sustainability is a bigger concept that involves more than just managing overflows.

    GREEN CITY, CLEAN WATERS: Commencing in 2011, Philadelphia’s 25-year program is creating a citywide mosaic of green infrastructure to capture the first inch of rainfall and restore the water balance, one “greened acre” at a time!


    Benjamin Franklin, Philadelphia’s favorite son, described his city’s stormwater problem well: By “covering a ground plot with buildings and pavements, which carry off most of the rain and prevent its soaking into the Earth and renewing and purifying the Springs … the water of wells must gradually grow worse, and in time be unfit for use as I find has happened in all old cities.” But Ben Franklin’s town has decided to take the lead in undoing this ever-more costly and outdated system.
