Protecting Filter Gallery Pipes for Water Treatment Plant

When rust, corrosion and coating system failure became apparent on pipes in the filter galleries of the Lafayette Utilities Systems (LUS) water treatment plant, a rehabilitation plan was developed. One of the most important aspects of this plan was to prepare the carbon steel surfaces and create the proper anchor profile for the new coating system. Depending on the severity of the rust and corrosion on various pipe sections, the specifications called for either near white metal blast cleaning or commercial blast cleaning.
