Sidwell Friends School: The landscape and building function as a single integrated system that is designed to capture, clean, and re-use wastewater from the school. Dirty water and sewage flows from the kitchen and bathrooms into settling tanks, where solids are removed, before being released underground in the constructed wetland. The water circulates through the landscape for three to five days before it is re-used in the building’s toilets and cooling tower. Photo: Andropogon Associates
An enlarged middle school building now includes an outdoor living laboratory that features a green roof, terraced wetland, rain garden, and habitat pond. This space functions as an extension of the classroom where students can learn about sustainable practices.
