Bagnell Dam – Lake Ozark, Missouri

Rampart Hydro Services has been working on a major dam rehabilitation project at the Bagnell Dam in Missouri. The Bagnell Dam was built between 1929-1931 on the Osage River creating the Lake of the Ozarks reservoir.  MC Industrial, Inc. is the general contractor completing the approximately $52 million project for the dam’s owner, Ameron Missouri.  The Bagnell Dam is a 2,543 ft long by 148 ft tall concrete gravity dam.  The hydrodemolition work will consist of approximately 80,000 SF of 4” concrete removal.  For this project, Rampart has designed and fabricated two brand-new pieces of equipment.  These new hydrodemolition cutting units will be able to scale the entire face of the dam to remove the concrete.  Rampart conducted a naming contest for our new unit and the winning name was the “Hydro Spyder”.  In addition to the hydrodemolition, we will also be performed wastewater treatment using our Automated Vacuum-Filtration System (AVS®).  The pH of the wastewater will be lowered to between 7-8 and the total suspended solids (TSS) will be reduced to less than 20 mg/L.  After treatment, the wastewater will be disposed of at the local wastewater treatment plant.
