News & Notes
Jetting Schedule
The City cleans 112 line segments on an annual basis. This work is completed
April to June. Work typically starts in the northwest part of Knoxville
and ends in the south part of Knoxville. In addition, all mains are cleaned
and televised once every ten years. City staff will hang door notices on
doors prior to cleaning mains.
Bio-solids Application
Staff presses sludge for 8-10 weeks in the spring and again in the fall.
The bio-solids are applied to fields twice a year, before planting and
after harvest. Bio-solids are applied at 3 to 4 tons per acre. Local farmer
interested in having bio-solids applied to their fields should contact
the Wastewater Department.
Sewer Backups
If a customer has a sewer back up and calls the City, staff will check
the applicable manholes to make sure that the City’s mains are not
plugged. If the City’s main is plugged, the City will clean the main.
If the main is not plugged, residents should contact a private sewer cleaning
service or private contractor to address the problem.
Sewer Odors
If a customer has a problem with a sewer odor they should call the Wastewater
Department and staff will check to see if the problem is on the City’s
main. If there is not a problem with the main, residents should check to
make sure all of their traps have water in them and that their vents are
not plugged. If the resident is not sure how to check these items, a plumber
should be contacted.

saddles to the job site and will stand-by during the tap cutting process.
City personnel will not enter the trench.
Contractors will be required to provide an air compressor and hose capable
of providing 70 cfm of clean air at 100 psi. If the contractor can not
provide the proper air, City personnel will provide a compressor for
a $40 fee. If the City is required to provide the compressor the tap
will be scheduled at a time convenient to the City and at a time when
the compressor is available.
