In 2015 BG was contracted to assist the City of Horton with improvements to their Wastewater Treatment Facility due to effluent permit limitation violations with the Kansas Department of Health and Environment. After conducting a study that identified options for improvement and replacement, it was concluded that replacement was the best option due to the existing facilities' condition. The final design consisted of the construction of a new wastewater treatment facility, lift station, and force main to connect the City’s collection system to a new wastewater treatment facility that is located on the south edge of the city. Careful coordination efforts were required to allow the existing plant to remain operable during construction as the new plant utilized the existing site.

The project included a new submersible lift station to handle both average daily and peak daily flows. Peak daily flows are pumped to a separate extraneous flow basin. Process flow is pumped to a headworks building with a mechanical screen, washer compactor, and grit removal equipment. From the headworks, wastewater is treated in a BNR extended aeration treatment facility. Wastewater is disinfected with a closed vessel UV disinfection system. Solids are aerobically digested, thickened, and applied to 9 sludge drying beds. The project also included a new administration building with a laboratory and controls room.

Financing for the project through the USDA Water and Waste Disposal Loan and Grant program was acquired with roughly 40% of the money coming as a grant.BG Consultants performed the initial site evaluation, preliminary analysis, project design, and construction administration.

This project was awarded the 2023 Kansas Rural Water Association Most Improved Wastewater System of the Year.
