Corps award contract for new pump station near Port Sulphur, part of storm surge defense system

The U.S. Army Corps of Engineers has awarded a $23.6 million contract to build a new pump station near Port Sulphur, part of an effort to reduce the risk of flooding in southern Plaquemines Parish.

The contract with New Orleans’ firm Healtheon, Inc., will allow construction of the new station and some fronting protection features at the location of the Sunrise and Grand Liard Pump Stations.

The project is the sixth contract awarded as part of the New Orleans to Venice project, which will offer some protection to areas outside the metro New Orleans federal levee system. The effort, which also includes raising a non-federal levee, is designed to shield the area from storm surge brought by a storm with a two percent chance of occurring in any given year.

The 24-month contract will include construction of a concrete T-wall in front of the pump stations, and an extension of the pump discharge pipes through the floodwall. The corps said Valves or gates will also be incorporated into the discharge pipes to prevent backflow.

The fronting protection is designed to reduce the effects of storm surge on the pump stations during a storm. Those features will bring the Sunrise and Grand Liard Pump Stations into compliance with new standards, the agency said, and should be completed in late 2015.
