In 2019, Thieneman Construction Inc. was awarded the Yorktown Guaranteed Saving Contract for the Wastewater Treatment Plant Improvements located in Yorktown, IN. The general project scope consists of furnishing all labor, materials, equipment, supplies and services for the construction and installation of a new Headworks Bldg, new effluent disinfection Bldg, and replacement of process equipment at the Primary Clarifiers, Secondary Clarifiers, aeration tanks and Biosolids Dewatering. The project incorporated upgrades and improvements at all steps in the treatment process. Therefore, the work had to be sequenced in a way that did not interrupt overall plant treatment capability.
