Knoxville Utilities Board (KUB) is the water provider for the City of Knoxville, TN and surrounding areas. The Mark B. Whitaker Water Treatment Plant (MBW WTP), KUB’s only water treatment plant, is a conventional filtration plant with a rated plant capacity of 62.9 million gallons per day (mgd). The plant was originally constructed in 1927 and has undergone numerous upgrades to expand and improve the existing treatment system throughout the years. The source water for the MBW WTP is the Fort Loudoun Reservoir, an impoundment on the Tennessee River, located approximately three miles downstream of the confluence of the French Broad River and Holston River. As part of KUB’s Water Supply Master Plan; a plan to reduce risk, increase redundancy, and increase resilience of the MBW WTP; KUB is constructing 38 mgd of additional filtration capacity. The construction of the new filters will create two separate treatment trains capable of supplying this demand to provide redundancy and resiliency in current operations and for use in future plant expansion. The additional capacity and separate trains will mitigate concerns over the long-term reliability of the existing filters that are now approaching 100 years old. The second treatment train will also allow for maintenance of the existing facility. Along with the construction of a new filter building to house the six new conventional gravity filters, the project also includes the construction of a new Intermediate Pump Station, Backwash Supply Tank, and Backwash Equalization Tank. A second laboratory and control room are also being constructed in the new filter building. Construction of the project is expected to be substantially complete in the Fall of 2025. This presentation will focus on the planning process of the new filtration train, with a focus on plant operations and risk mitigation. The presentation will discuss the results of the project, including a discussion of project drivers, value engineering, and the implementation of the project.
