Orleans Avenue

Did you know that...

When fully operational, the three pump stations combined will be able to pump 24,300 Cubic Feet Per Second or 181,777 Gallons Per Second. That is enough water to fill an Olympic-sized swimming pool in 3.63 seconds or fill the Superdome in less than 90 minutes!

Approximately 8,000 tons of reinforcing steel will be used on this project. That will surpass the amount of steel in St. Louis' Gateway Arch by 2,000 tons!

Orleans Avenue PCCP

The Permanent Canal Closures & Pumps (PCCP) will be composed of permanent gated storm surge barriers and brick façade pump stations at or near the lakefront.  The pumps will move rainwater out of the canals, around the gates and into Lake Pontchartrain during a tropical weather event, and be equipped with a stand-alone emergency power supply capacity so that it can operate independently of any publically provided utility.

When complete, the PCCP at Orleans Avenue will consist of three 900 cfs pumps and have a total pumping capacity of 2,700 cfs; the PCCP at London Avenue will consist of four 1,800 cfs pumps and two 900 cfs pumps and have a total pumping capacity of 9,000 cfs.
