In an Army Corps of Engineers press release, details on the astounding rate at which workers are draining water from New York's subway and transit tunnels: "To date, the USACE has used about 50 pumps of various sizes to remove 64 million gallons of water from the New York City mass transit system. Operations are ongoing at six sites, with pumps removing about 116,000 gallons per minute. The 696,000 gallons the pumps are draining each minute exceeds the amount of water in one Olympic-size swimming pool (660,000 gallons). There were roughly 600 million gallons in the tunnels when pumping operations began on Thursday, Nov. 1." (via Noah Shachtman).
