Harahan, Louisiana – SELA Flood Control Project

In the Spring of 2014 Eutaw Construction commenced work on the North Discharge Tubes project located in Harahan, LA.  This is a highly complex project that is a part of a larger “Pump to the River Project” which is being implemented by the New Orleans District of the Corps of Engineers to control flooding in Jefferson Parrish Louisiana.  This project consist of installing 5,100 LF of three adjacent (Triple Barrel) 84” diameter pipes, installed at depths up to 23 feet deep in a sheet pile cofferdam.  The sheet pile cofferdam consist of approximately 225,000 SF of sheet piling 65 feet long, along with approximately 3,500 LF of 36” Beams and approximately 2700 LF of 24” steel pipe struts that will be installed and removed throughout the course of this project.  The project ROW is extremely narrow with active traffic on both sides and overhead high voltage power lines that run the full length of the project.

Eutaw’s portion of the project will connect to a large pump station on the north end, and to existing 84” pipes to the south (which Eutaw installed in 2008).  When completed, floodwater will be pumped from the intake at the pump station through approximately 2 miles of pipeline, to an outfall structure in the Mississippi River.
