WTP modernization retains Little Rock history | 2022 WWD Top Projects

Jan. 27, 2023
Little Rock, Arkansas, facility upgrades flocculation/sedimentation basins and filters while retaining the plants historic look and feel.

The Ozark Point Water Treatment Plant has served Little Rock, Arkansas, atop a hill overlooking the city since the 1880s. The age raised concerns over the health of the concrete for the flocculation and sedimentation basins, one of which dates back to original construction and the second of which dates back to the late 1920s.

Tad Bohannan, CEO of Central Arkansas Water, explains why retaining the historic look of facility was important for the community. Tom Crowley, project manager for Carollo Engineers, discusses the challenges involved with updating a more than 140-year-old, including space limitation and bringing the plant up to code.
