Document Description
The Sierra Del Oro Water Treatment Plant Flocculation Basin Baffles and Mounts Rehabilitation Project includes the removal and replacement of the existing deteriorated wood baffles and mounting brackets with new fiberglass reinforced plastic (FRP) baffles, along with 316 stainless steel mounting brackets and anchor bolts. Additionally, the work involves structural rehabilitation of degraded concrete surfaces, the application of a concrete corrosion inhibitor, and installation of a new epoxy coating. These improvements are essential to maintaining efficient mixing, treatment performance, and overall water quality within the flocculation basins. By replacing aging materials with durable, corrosion-resistant components, the project supports reliable plant operations, reduces long-term maintenance needs for operational staff, and ensures the continued delivery of high-quality drinking water to the residents of the City of Corona.
