NOAB Drainage (Airport Storm Water) Pump Station

This project was designed to help remove flood waters from hurricanes and heavy rain storms at the Louis Armstrong International Airport located in Kenner, Louisiana.

It took four separate 60″ discharge water lines, which were run parallel to each other to remove water from the airport and back into the canals. The pipe had to be fabricated to precise dimensions in order to rest on the thirty eight above grade cast in place concrete supports that supported the pipeline. Thirty-two harnessed flexible couplings were added to ease installation and allow for settlement.

To add to the difficulty, the four pipelines made two long sweeping turns and at one point, had a twenty-five foot drop and rise in elevation to allow for a service road to pass over the top of the pipe.

All the pipe was cement mortar lined per AWWA C205. The coating was a three part coating system.  The first coat consisted of a zinc primer coat, followed by a coat of coal tar epoxy coating and then top coated with an aliphatic coating to prevent UV deterioration.  All the steel and components for the project were AIS compliant.
