1 Wastewater from the entire building flows into a holding tank where solids settle, like in a septic tank. The reclaimed liquid up top gets pumped to the lobby.
2 Garden-like “wetland cells” layered with plants, soil, and rocks collect the water and capture biological compounds and pathogens.
3 On its way out of the garden, the water is further sterilized by ultraviolet light in the pipes. Then it’s recycled back into the plumbing system.
