Document Description
The Diemer Plant's filter outlet Conduit and Finished Water Reservoir inlet conduit feature surface-mounted, steel hatch covers for personnel and equipment access during maintenance work. These hatches were installed during the original plant construction in the 1960's. Fifteen steel hatch covers are severely corroded, resulting in misalignment and partial closure. Some of these hatches have rusted openings, resulting in a potential cross connection, and some of the concrete curbs supporting the hatches are spalled. The Metropolitan Water District of Southern California proposes to replace the 15 hatches and repair of the concrete curbs are recommended to improve workplace safety and protect water quality. This action includes the final design of these upgrades.
