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).

    Since they’re the government, I assume that that’s not very impressive, and that the Private Sector ™ could do a much better job.  If the government would get off of their back.

    So it will be ~10 dys until the water is all out. Then inspections. Then repairs. I hope a lot of people realize that lower Manhattan probably won’t have subways for a while yet.

    This would be a great opportunity to update and modernize the affected train lines. I hope the governors of the affected states are big enough to accept federal assistance with such a massive job-creating project.

    Something makes me think their numbers are a bit screwy:

    At Start 600,000,000
    Removed so far* 64,000,000
    Remaining* 536,000,000

    Gallons per minute 696,000
    Minute for remaining 770 (12:50 in hours)

    *as of time of press release

      Right.  Same thing arranged differently:

      660,000 gals x minute.
      6,600,000 gals in 10 minutes.
      66,000,000 in 100 minutes.
      660,000,000 in 1000 minutes (around 16 hours, 40 minutes).
      Minus 60,000,000 (about 90 minutes) = 15 hours, 10 minutes, give or take a few minutes, to drain six hundred million gallons of water, at the claimed rate.

    As more climate events occur, the Corps of Engineers might be the only ones with the logistics capability to fight their effects.

    I guess the military-industrial complex was worth it after all…except that the DoD is the a worse polluter than the rest of the government combined and is exempt from many regulations.

    But what an amazing achievement! I was astounded when I heard that parts of the subway were running after less than a week. This was the D-Day of storm operations

    It’s nice to see that they’re using one of The Register’s units of measure, the Olympic-sized swimming pool:
