Town of Veedersburg Wastewater System Improvements

This BOT project included rehabilitation/replacement of 5 of the towns’ 8 lift stations. Improvements at the Primary Lift Station included but were not limited to protective lining/coating of the existing wet well & valve vault structures, new duplex submersible non-clog lift station pumps with all required accessories (guide rails, level controls, etc.), piping, valves, access hatches, painting, and 6” interconnecting pipe to the existing 6” force main from the old wet-pit/dry-pit lift station with an electrically actuated shut-off valve.

The WWTP improvements included construction of a new biological treatment process with an orbal style oxidation ditch and two (2) 40’ diameter secondary clarifiers. In addition to the new biological treatment process, other improvements included a new influent screening and diversion structure, modifications to the existing larger Biolac treatment basin to serve as an emergency bypass basin for additional emergency storage, and a new return activated sludge/waste activated sludge (RAS/WAS) pumping facility with common wall construction with the secondary clarifiers. The project also included re-use of the existing north plant sludge tank & conversion of one of the existing north plant clarifiers to a digester, new decanting system, modifications to the existing aeration blowers (to provide the required aeration to the digesters) including VFD’s, replacement of the UV disinfection system with a non-contact type UV system, new post-aeration tanks, and elimination of the northernmost sludge drying bed.
