Question from Patrick Serfass to
@dgneighbour and@ScottHoustonCA - how do we deal with the challenge of a combined sewer system that reduced the effectiveness of wastewater treatment?Pokaż ten wątek -
@dgneighbour: Only new cities have separated systems, and they're incredibly difficult/expensive to implement in existing cities. Look at#NewYork as an example - public awareness can lead to less water usage.Pokaż ten wątek -
"The more concrete we have in a city, the more water will go into sewers and potentially overflow wastewater systems." -
@dgneighbour Green infrastructure that absorbs rainwater is key for avoiding sewer overflows.Pokaż ten wątek -
From Dr. Jennifer Turner - China's cities are trying to implement a "Sponge City" initiative to soak up more rainwater and prevent sewage overflow. Not only does green infrastructure absorb water, it helps make a city livable!

Response from Patrick Serfass from
@ambiogascouncil: The carbon is generally released, but the methane, which is 20-100 times worse than carbon as a greenhouse gas, is captured. That leads to a net carbon-negative impact.#sustainablePokaż ten wątek

@dgneighbour: Stormwater is the greatest enemy to the technology we've been talking about today because it reduces effectiveness of wastewater treatment. You can't have cookie-cutter solutions - they have to be hyperlocal. Great examples of stormwater management in Singapore.Pokaż ten wątek
