Jones Street Pump Station

May 15, 2022

The existing Jones Street Pump Station was constructed in 1953 and conveys flow beneath the Tennessee River through a 24-inch diameter flexible joint iron pipe. Knoxville Utilities Board (KUB) has deemed the pump station is scheduled for a capital upgrade after a routine evaluation of its’ life cycle, due to its’ limited capacity and age.

In support of the upgrade, a new pump station with a depth of 47’ and associated facilities are planned for the new 1901 Jones Street site, approximately 500 feet south of the existing pump station. The project site is currently a combination of surface parking lot and storage area for natural gas tanks. The natural gas tank storage area is situated within the footprint of a former warehouse that has been razed. Remnant foundations for the warehouse remain.

As part of the project, a new 24-inch-dimeter force main will extend from the proposed pump station to the north toward the existing pump station. The force main then turns to the west and follows the river for approximately 960 feet, until turning north, crossing the Tennessee River and terminating at an existing manhole on the Tennessee Valley Authority (TVA) property. This project will be approximately 1,500 LF of force main that is time restricted from Jan. 1-Feb. 2.

In addition to all the aforementioned upgrades and new infrastructures, this site will also include: A New 42” Diameter Gravity Sewer, Marine Pipe crossing, approx. 200 LF of 6, 8 and 12-inch gravity sewer routing and, as well as, numerous other miscellaneous site improvements.
