Weeks ahead of schedule and under budget, DuPont has completed a project aimed at protecting its DeLisle, Mississippi titanium dioxide plant from hurricanes, PRNewswire reports. The plant was badly damaged last year after experiencing a direct hit from Hurricane Katrina. The site resumed manufacturing operations in January. When the flood protection project was announced in April, DuPont estimated that it would cost $15 million to $20 million to top the plant''s existing 20-foot earthen levee with a 10-foot flood wall. The final cost is now estimated at $12.5 million. The enhanced levee/flood wall stands 32 feet tall. Construction of the so-called "sheet pile" wall required 4,000 sheets of steel, each measuring 27-inches-wide and 38-feet-long. Some 286 truckloads of steel, weighing eight million pounds, were delivered to the site. The sheets were driven vertically into the ground until the desired height was achieved. Construction began in May and was completed in mid-July. Now fully operational after months of intensive reconstruction, the titanium dioxide plant is running at near-capacity rates.
