As of 2017, the New Orleans pumping system - operated by the Sewerage and Water Board - can pump water out of the city at a rate of more than 45,000 cubic feet (1,300 m 3) per second. [1] [2] The capacity is also frequently described as 1 inch (2.5 cm) in the first hour of rainfall followed by 0.5 inches (1.3 cm) per hour afterward. [2]
The 17th Street Canal is the largest and most important drainage canal in the city of New Orleans. Operating with Pump Station 6, it moves water into Lake Pontchartrain.

By September 6, 2005, the pump stations began to get online on 17th Street Canal. Pump Station 10 was actually pumping at this point. Pump Station 6 was interrupted to clean up some debris out of the area. Pump Station 1, which is a little bit further up in the system, was pumping to Pump Station 6, so as to drain the upper area, uptown areas.
The pump station complex, which is the largest of its type in the world, consists of 11 each 5,444 horsepower Caterpillar engines. To minimize environmental impacts to the Bayou aux Carpes 404(c) area, the floodwall was constructed on the eastern edge of the wetlands, within 100 feet (30 m) from the western bank of the GIWW for a 4,216 feet ...
During each wave of rainfall, heavy, "training" thunderstorms continued to form over the same areas for multiple hours. In the New Orleans area, pumping stations were overwhelmed and could not pump rainfall into Lake Pontchartrain as quickly as it was falling. At the time, pumping stations were only rated to pump 1 inch (25 mm) per hour maximum.
In canal systems, pumping stations help replenish water lost through lock usage and leakage, ensuring navigability. Similarly, in land drainage, stations pump water to prevent flooding in areas below sea level, a concept pioneered during the Victorian era in places like The Fens in the UK. The introduction of "package pumping stations" has ...
