Please join us for a lunch presentation by Logan Forythe, Civil Engineer at Black & Veatch St. Louis, and Karen-Marie Dietze, Process Engineer at Black & Veatch Kansas City, on their recent project for the Hannibal Board of Public Works. In 2017, City of Hannibal voters passed a referendum requiring the City’s water treatment plant (WTP) to discontinue the use of chloramine treatment and transition to free chlorine. With the support of Black & Veatch, the City evaluated treatment alternatives, distribution system modifications, and the City’s historical data to ultimately recommend a long-term solution that can address the public's concerns while meeting regulatory requirements for DBPs.
This presentation provides an overview of the initial alternatives analysis, GAC pilot testing, and design and construction of a new GAC treatment facility at the Hannibal, MO WTP.
