Sidwell Friends Middle School Washington, D.C.
Waste management isn’t the most glamorous of topics, says co-curator Deborah Sorensen, but it is profoundly important whenever you talk about sustainability and schools. She calls Sidwell Friends Middle School, a private school in northwest Washington D.C., a “showcase project” in this regard. In addition to a green roof and a photovoltaic array, which supplies five percent of the building’s electricity, the school, renovated in 2006, has a beautifully constructed wetland that filters wastewater. Once the bathroom wastewater passes through a settling tank, and then the wetlands, where microorganisms assist in cleaning it, and yet another filter, the resulting “gray water” is channeled back into the school’s bathrooms.
