New Orleans Large Diameter Steel Force Main Condition Assessment Using Alternate Failure Criteria
The wastewater system backbone of the New Orleans Sewerage & Water Board (the Board) is comprised of large-diameter, steel force mains in diameters from 54- to 72-inch size. During Hurricanes Katrina and Rita, the town and associated infrastructure experienced damages associated with the flooding resulting from these storms. In 2005, two back-to-back major storms inflicted great damage on the City and the surrounding area. On August 29, 2005, Hurricane Katrina hit the Louisiana coastline as a Category 4 storm. The water level in Lake Pontchartrain peaked at 8.6 feet (7.6 feet above the normal sea level). Breaches in the levees built to protect the City occurred at the 17th Street Canal, the London Avenue Canal, and the Industrial Canal. The breaches led to flooding in nearly 80 percent of the City with water depths reaching 25 feet in some areasand adding very large external loads to the existing forcemains. Less than a month later, Hurricane Rita made landfall on September 24, 2005, as a Category 3 storm. Levees were again overtopped in at least three locations along the Industrial Canal, re-flooding the City's Lower Ninth Ward, a few neighborhoods surrounding Lake Pontchartrain, and neighboring St. Bernard Parish.
