The Tomahawk Creek Wastewater Treatment Facility project was named the Engineering News Record’s National Best Project for Water/Environment, officially designating the project as “Best of the Best.”

Treatment Assistant Superintendents Alison Cioffi and Kenya Woods, and Asst. Chief Engineer Tami Lorenzen, attended the ENR ceremony in New York earlier this month to accept the award. The Board of County Commissioners and County Manager’s Office recognized Johnson County Wastewater for this award at their Feb. 15 meeting.

Previously, the project was awarded the Water/Environment Best Project for the ENR Midwest in August 2023. Nearly 200 regional winners were promoted to the national competition, and from those entries, 20 national winners were selected.

Completed in spring 2022, the Tomahawk Creek Facility was renovated to handle increased flow due to the population growth. The project tripled Tomahawk’s treatment capacity and is expected to save almost $800 million in operating costs over the next 35 years. It was completed on time and on budget.
