Green Infrastructure for Runoff | Elizabeth Fassman-Beck, Ph.D. | TEDxStevensInstituteofTechnology
Ever wonder what happens to runoff when it rains? Most of us take for granted that rain overflow simply diverts to the sewer system, but in actuality, it poses a significant problem. Combined sewer overflows (CSOs) are caused by urban stormwater runoff, but result in uncontrolled discharges of raw sewage into receiving waters surrounding urban centers across the globe. In other words, a water quantity problem causes a water quality impact. Rooftops contribute a large proportion of a city’s runoff-generating surfaces, but because they’re out of sight, they’re also out of mind. This talk will introduce you to several green infrastructure technologies specifically designed to tackle the unique engineering challenges of reducing rooftop runoff, and identify what we still need to learn to address this critical infrastructure issue.
Dr. Elizabeth Fassman-Beck is a civil engineer specializing in urban stormwater management using green infrastructure. Her work linking the design to hydrologic and water quality performance of technologies such as living (green) roofs, bioretention/rain gardens, permeable pavements, and floating treatment wetlands is published in leading engineering journals. Elizabeth won the 2014 Wesley W. Horner Award from the American Society of Civil Engineers (ASCE) for technical research on living roofs, co-authored the 2015 technical reference Living Roofs in Integrated Urban Water Systems, and has created technical specifications for regulatory agencies in Auckland (New Zealand) and North Carolina. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

local wqs, this summed up the fight for green infrastructure so eloquently, get out there and tell your local government you want to see more green infrastructure!!
Our local Government releases smoke into the sewage system and drive around to see if any storm water pipes are giving off this smoke. The owner is told to disconnect his run off from the sewage system as it is illegal. Storm water flows into local parks which are retention ponds, then released after the peak. Farmers up river flood their land to take water out of the flooding river.
Great and undeniably very informative presentation!
WOW! Great example of green infrastructure!
Lovely. My Master's research project studies this in the context of Canadian cities!

Eye-opening! Now I understand the purpose of harvesting storm water before it creates contamination issues on our drinking water supply. Great presentations!
Very interesting. Helped a lot with my research. Thank you
Green infrastructure solutions are rather site-specific. For example, suburban communities with ample green space can do things like rain gardens for storm water retention. Good presentation.

Rainwater harvesting is great exactly because it is decentralized. It recharges the water table; reduces pollution in a low-tech, low cost way; it reduces community water bills;, it can increase roof life; reduces heating and cooling costs, etc. Bioswales and curbcuts can do a lot to change communities. Look up Brad Lancaster's hour+ videos. He has very practical solutions.
Great and very informative talk! Thank you for bringing attention to this important topic.
Well done! I'll share with my folks how the green infrastructures really important in our life . Thanks!
Really liked the simple interpretation and clear focus on range of possible applicability ..high time we understand run-off importance and start implementing such initiatives at various level ..
Storm water runoff here in the northeast has yet to be quantified on the aggregate impact on the benthic trophic biome. It's a numbers game.

This is going to be even more important with increased rainfall that will occur due to the warming of the earth.
Oh, nice. Just ran into this video. Let's do compared to other country so that we Americans can look great. I believe it is not necessary to use other country to compare to our have and have not. If that is so important than why is nothing being done about it, talk is cheap but that is what we American do best, so blame how other country are so unsanitary.

Her point is to shock us about our own stormwater by using common biases.
What if those people were perfectly fine with their "water conditions", rivers are self cleaning. You can build something called a burm based on its principals. This strikes me as a first world person preciving a third world problem like "they don't know Jesus" kinda thing.

Her point is to shock us about our own stormwater by using common biases. Water has to travel a certain distance to become 'self cleaning.' Additionally she didn't pull any punches about our own water quality issue.
