On display at studioMAIN in downtown Little Rock, Arkansas, are dozens of poster boards showcasing projects completed by local civil engineering firms. Among them, is RJN’s Headworks & Ultraviolet Disinfection Improvements – the Davidson Drive Hot Springs WWTP Design-Build.
For the months of October and November, the non-profit gallery displayed poster boards that highlighted select projects of local engineering firms. During the city’s monthly Argenta Art Walk, the boards were seen by additional visitors of the studio, which is connected to, and surrounded by, other local art galleries.
RJN’s poster board represented the Hot Spring’s Design-Build project for the City’s new Davidson Drive Wastewater Treatment Facility, which was completed in January of last year, replacing their rapidly deteriorating plant. Despite the last-minute addition of a new non-potable water system, the project was still $400,000 under budget totaling $8.6 Million. Click to see a PDF of the poster on display.
Key highlights of the new WWTP included the replacement of the bar screens and grit removal system at the headworks of the facility, with new mechanical fine bar screens and grit removal equipment designed for 12 MGD average daily flow. The gaseous chlorine/disinfection system was replaced with UV disinfection, capable of peak flows of 44 MGD. Flows above the peak volume are diverted to the flow equalization basin by way of a permanent manual barscreen and by-pass, which was also constructed during the 1.12 year time frame.
