Built in 1955, the City of Kingsport’s Wastewater Treatment Plant has experienced upgrades in 1965, 1982, and is currently undergoing a continuous improvement process. The plant currently treats an average of 9 million gallons of wastewater per day. The process includes screening, grit removal, solids settling, biological treatment, clarification, disinfection and solids stabilization.
An engineering study was completed in 2001 that outlined a multiphase plant rehabilitation and upgrade plan. The study identified and ranked plant deficiencies based on an assessment of plant equipment performance, benchmarked current industry standards and State & Federal permit requirements. Completion of the phases of this project will replace nonfunctional equipment and provide upgrades that will enhance plant performance.
- Replace failing mechanical units
- Upgrade plant technology
- Modernize plant to industry standards
Project Status :
First phase projects are complete and include: influent line repair/replacement, centrifuge upgrades, new blowers and piping for aeration, installation of redundant new polymer system and various pumps.
Phase II projects are underway and include barscreens, grit system, waste station, gravity thickener and various pumps with completion in Summer 2004.
Phase III is under design and includes: SCADA/telemetry, basin improvements and digester upgrades to begin construction in Summer 2004.
