Gowanus Flushing Tunnel

To address water quality problems, the Gowanus Canal flushing tunnel system was originally constructed in the early 1900s to provide flushing of the Canal by withdrawing water from the head of the Canal, conveying it through a 1.15-mile tunnel, and discharging at Buttermilk Channel. The pump house at the head of the Gowanus Canal at 201 Douglass Street contains technology from last century when the tunnel to Buttermilk Channel was used to bring fresh water into the canal. Using a ship's propellor to suction the water, it suffered numerous catastrophic failures and finally stopped working for good in 2000.
