Document Description
Inspection of the Robert B. Diemer Water Treatment Plant (Diemer Plant) Finished Water Reservoir (Reservoir) revealed that there are cracks on the north and west walls. The cracks were caused by external surcharge pressure from an adjacent retaining wall. Currently, the surcharge load on the Reservoir walls has been relieved following cutting and removing a portion of concrete slab outside the walls. Metropolitan proposes to fix over 1,300 feet of cracks by injecting epoxy from inside the Reservoir during the next shut down in March 2006, which will last approximately five days. The proposed procedure for repair is as follows: (1) install scaffolds; (2) route at the cracks by drilling holes along the cracks and installing injection ports; (3) seal the cracks with paste epoxy between the injection ports; (4) inject epoxy through the injection ports; (5) grind out the injection ports; and (6) detail and clean the surface of cracks. All activities will take place within the Diemer Plant.
