Two weeks ago pipes started to appear in the Gowanus near the Third Street bridge, they have now snaked their way almost to the Carroll Street Bridge. Apparently it's the work Department of Environmental Protection. Does anybody have any idea what they are doing? A while back they spoke of pumping oxygen into the Canal as a plan to revive the ecosystem. Is this it or another thing all together?
*Update: Thanks to some members of F.R.O.G.G (Friends and Residents of the Greater Gowanus) who read the Army Corp of Engineers newsletters who kindly sent me the info,here is the deal with the pipes from that source.
"NYCDEP has authorized the Army Corps to install intake and pipes in association with an upland, temporary Canal Aeration-Oxygen Transfer Station along the Canal. . .
The work involves installation of 28 linear feet of 20 inch diameter intake pipes with an intake velocity of less than 1 foot/sec and a fish barrier with 1" diameter openings at the opening of the existing Flushing Tunnel intake. Approximately 2,500 linear feet of 24-inch diameter high density polyethylene oxygenated water discharge pipe would be installed with discharge nozzles spaced approximately 50-feet on center and and secured to 750 pound concrete anchors spaced every 10-feet. . . The pipe would be suspended in water depths ranging from 0 to 12-feet below the plane of mean low water. . . ."
The purpose of this project is to maintain dissolved oxygen levels for about two years while the flushing tunnel is closed down for upgrading."
So, it looks that the pipes will be there for a while.
