Current WWTA Sewer Rehabilitation Project Information

Click here to access the construction notification letter for the Signal Mountain Infrastructure Rehabilitation Plan 7-17-24.

The Signal Mountain sewer improvements plan consists of a three-phase approach of treatment plant upgrades, gravity line rehabilitation, pump stations, and low-pressure sewer conversions. These projects are being funded by a combination of American Rescue Plan Act (ARPA) grants, Tennessee State Revolving Fund (SRF) loans, and WWTA Capital Improvement Funds.  The ARPA grants are time-sensitive and will be lost if it is not spent by September 2026. It is of utmost importance that the WWTA use the available ARPA grant to the maximum extent possible on the sewer rehabilitation portion of this project. Although the other phases of this project are still being considered, redirecting the focus to the rehabilitation of the gravity sewer system on Signal Mountain in the selected priority areas is relatively straightforward and can be performed pursuant to the ARPA timeline.

The current sewer rehabilitation project will involve trenchless cured-in-place pipe rehabilitation for gravity sewer with diameters between 6-inch and 15-inch with an approximate total linear footage of 33,300. Approximately 209 laterals will also be rehabilitated using trenchless pipe methods. Approximately 110 manholes will be rehabilitated using either polyurethane/polyurea or epoxy coating methods. Approximately 51 manholes will receive a new watertight frame and cover and approximately 47 manholes will receive a new standard frame and cover. In addition, approximately 11 external point repairs, 3 spot repairs of CIPP liner and 10 lateral seal connection liner installations may be required. Additional repairs may be required as the work progresses.  A map of the current construction area in enclosed. A preliminary construction schedule will be available soon.  As with any construction project, the schedule is subject to modification. Here’s a map of the current construction area. The construction schedule will be available upon finalization by the contractor. 

The WWTA, EPA, and TDEC recently finalized the Consent Decree which stipulates that failure to meet regulatory requirements and deliverable deadlines will result in fines for non-compliance. Regulatory requirements aside, the chronic overflows of wastewater into creeks and streams on Signal Mountain are unacceptable. The WWTA is working to solve these non-compliance issues in a fiscally responsible manner.  

Please visit the Signal Mountain section of the “In Your Community” heading near the top of the WWTA website for a timeline of previous presentations and project communication regarding this project.  Updates will be added to the website as that become available.
