In December 2005 AmerenUE’s Taum Sauk Plant, located in Missouri near St. Louis, was closed indefinitely after the upper reservoir breached. After many feasibility studies, a complete rebuild of the upper reservoir was decided by the US Federal Regulatory Commission (FERC).

The project management assigned the construction works to Rizzo Ass Selected Ozark while Buzzi Unicem USA was awarded the cement supply for the entire project. Main supplier will be our Selma plant. High volume RCC (Roller-Compacted Concrete) pouring began this spring while the project is scheduled to be  completed by mid 2009. Approximately 2.1 million cubic meters of RCC and 230,000 cubic meters of conventional concrete will be needed to rebuild the reservoir.
