The Flushing tunnel is designed to bring water into the canal from the East River and from Buttermilk Channel, which will significantly improve water quality.
According to Gary Kline of New York State's Department Of Environmental Conservation, who shared the news with Friends And Residents Of Greater Gowanus, "dissolved Oxygen results in the canal for the past 2 weeks have been between 9-12 mg/l since the City brought the third pump on line for testing. This is a significant improvement in a very short time... Sample results also indicate that there has been no significant increase in turbidity observed during the start up period as the tunnel has gone from 1 pump to now all 3 pumps in operation.. The start up turbidity sampling is to conclude next week.... I hope the community will notice a major improvement in water quality this summer as compared to the past three years during the construction. The sewage pump station also nears completion and start up testing."
The equipment has been out of commission since 2009, when the City began to upgrade both the Gowanus Canal Flushing Tunnel and the Waste Water Pumping Station.
The upgrades cost $190 million and were supposed to already be completed. The project, ran into delays when flood waters submerged the new equipment during Hurricane Sandy.
