Benton Wastewater Improvements

The City of Benton’s wastewater treatment plant features a two-cell facultative lagoon, a Moving Bed Biological Reactor (MBBR) for ammonia polishing, and a UV disinfection system. Heartland Engineering has been actively assisting the City with project funding and the design of a comprehensive rehabilitation plan for both the wastewater treatment and collection systems.

With funds from the Missouri Department of Natural Resources State Revolving Fund (SRF), Heartland Engineering inspected the City of Benton collection system and designed a retrofit for the wastewater treatment facility. The inspection process included jetting, cleaning, and video assessments of the clay pipe collection system, which resulted in a detailed, system-wide view where specific issue were identified so that targeted repair solutions could be created.

The wastewater treatment plant has faced compliance issues with the Missouri Department of Natural Resources for several years due to effluent concentrations. The new design will incorporate influent flow measurement and screening, lagoon sludge removal, improved lagoon aeration, creation of an additional cell via a curtain, and repairs to the MBBR system.

Construction is anticipated to commence in 2025, and the project is expected to be fully operational by 2026.
