I had the pleasure last week of visiting an enormous valve chamber 200′ beneath Central Park for the official opening of City Water Tunnel No. 3.

New York City Mayor Michael Bloomberg was there to offer his own perspective on the value of urban infrastructure, and the colossal valves themselves were opened only a few hours later, bringing drinking water through the $5 billion tunnel, to residents of Lower Manhattan, for the very first time.

After no fewer than 43 years of construction, it was a pretty amazing ceremony to attend, sitting there at the end of Bloomberg’s reign, amidst security personnel, in a cathedral-like space beneath Central Park, reporters spread out across pews of blue plastic chairs arranged in what felt like a Romanesque side-chapel radiating off from the barrel vault of the central nave.
A manhole beneath our chairs was a surreal indication that, even here, 200′ beneath the city, much deeper levels lay hidden below (in fact, the actual water tunnel itself was another 400′ beneath us).
