What does it take to keep the world in unison? While delving into the world’s largest metropolis, I discovered an extraordinary feat of environmental engineering deep underground. The facility featured in these photographs is part of the Metropolitan Area Outer Underground Discharge Channel. Built between 1992 and 2006, this colossal stormwater management system is designed to handle overflow from six rivers. Although similar infrastructure exists worldwide, the sheer scale and ambition of this system are truly unparalleled.
