"Blueprint Columbus" Will Turn Infrastructure Liabilities into Green Assets
Clean Streams, Strong Neighbourhoods
Blueprint Columbus is an exciting new opportunity that is being explored by the City of Columbus, Ohio. The City’s focus is eliminating sanitary sewer overflows while also investing in neighbourhoods and the local economy. Instead of simply storing excess water that seeps into the sanitary sewer system when rain falls and snow melts, Blueprint Columbus will address the source of the problem, where rain falls.

Treat the Cause, Not the Symptom
City of Columbus staff overseeing implementation of the City’s Wet Weather Management Plan (WWMP) began asking:
“Is there a better way? Can we solve the problem of sewer overflows in a way that leaves a visible, long term improvement in our community?”
The timing was right because shortly after these questions were posed, the US Environmental Protection Agency (EPA) issued a policy encouraging the solution the City was considering: integrating the work required by the consent decrees and detailed in the WWMP with work required under regulations on the stormwater system.
“What made Columbus Mayor Michael B. Coleman take pause was that while the costs of building additional storage capacity were high, the benefits were markedly low and limited. The project would result in a new piece of infrastructure used maybe four or five days a year, and it would sit underground, literally, doing nothing for the landscape of the city and its citizens,” writes Steve Goldsmith in an article published on governing.com.
According to Dax Blake, the city’s assistant director of sustainability and its administrator of sewerage and drainage, “the goal of Blueprint Columbus is to ‘treat the cause, not the symptom’, This means working with residents to improve drainage from homes by installing sump pumps, redirecting roof run-off and repairing ‘laterals’, the pipes that carry wastewater from houses. And on a larger scale, it involves building a system of green infrastructure to keep excess stormwater from entering the sanitary system in the first place.”
Challenges
While there are many benefits, there are also many challenges presented by this approach. Removing the source of water seeping into lateral pipes on private property is much more visible and invasive from the homeowner’s perspective. The City may need to: replace/rehab downspouts and gutters, disturb front and back yards, build in the street right-of-way.
“What we’re seeing in cities like Columbus is part of a trend toward using green infrastructure to meet specific needs of utilities while generating a host of additional benefits for their communities. These cities are turning their infrastructural liabilities into assets,” concludes Steve Goldsmith.
