Fort Smith confronts costly water pipeline, plant expansion needs

Fort Smith officials proposed a $585 million plan to upgrade the city's water infrastructure, including expanding the Lake Fort Smith treatment plant and constructing a new 48-inch transmission line. During an August 26 study session, the Fort Smith Board of Directors discussed the project's scope, which is divided into five phases. Phase 1 has been completed, while subsequent phases are in various stages of design and planning. Currently, the city relies on two aging water lines, with the most recent addition dating back to the 1960s. Acting city administrator Jeff Dingman noted that the new transmission line will enhance water service reliability and reduce maintenance issues associated with existing infrastructure.

The estimated costs for the upgrades range from $328 million to $585 million, influenced by federal and state funding. Lance McAvoy, director of water services, indicated that costs reflect current construction trends in Northwest and Central Arkansas. The redundancy of the new lines will allow for maintenance without disrupting water supply to Fort Smith and Sebastian County customers.
