Project Description: With much of the existing equipment nearing the end of its useful life, renovation of the Smithville Wastewater Treatment Plant was necessary in order to reduce failures which could result in sanitary sewer overflows, permit violations, and regulatory fines. This $2.8 million project was partially funded by a grant from the Tennessee Department of Economic and Community Development. Renovation of the wastewater treatment plant included construction of a new influent pumping station, headworks, sequencing batch reactor motive pumps, effluent pumps, supervisory control and data acquisition system, and electrical building. The influent pumping station utilizes three (3) variable speed submersible screw centrifugal pumps to lift water into the new headworks. The new headworks consists of one new ¼ inch mechanically cleaned fine screen followed by one vortex style grit removal unit. Bypass channels and one manual bar screen are provided for headworks equipment maintenance. The equipment replaced by this project had been in service since the early 1970’s and early 1990’s which is a testament to the facility being well maintained by City of Smithville staff.
