Quality. Water. Life.

Chattanooga in 50 years has gone from being the most polluted city in America to a celebrated renaissance community. The natural resources that frame the city – the Tennessee River, Lookout and Signal Mountains – combined with an 18-mile Riverwalk make Chattanooga a great place to live, work and play. 

The revitalization of Chattanooga began with a focus on water through the construction of the country’s only freshwater aquarium. This development on the shores of the Tennessee River sparked a multi-year commitment to use the natural resources of the community as the foundations for revitalizing the downtown, restoring the relationship between natural resources and a great mid-size city.

Overflowing Manhole

The Current Problem

Portions of our wastewater infrastructure system are reaching the end of their useful life. This contributes to failures in the wastewater system. These failures mostly occur during heavy rain events when there is not enough capacity in the wastewater system for the high volume of stormwater and wastewater. This can lead to sanitary sewer overflows (or SSOs) SSOs pose a potential threat to public health, the environment, and the City’s economic development.

Committed to Change

The City of Chattanooga is committed to providing the best water quality and wastewater service. Clear Chattanooga is the City’s community-wide improvement plan to decrease the number of SSOs and to meet the terms of its Consent Decree agreement with the Environmental Protection Agency, the State of Tennessee and the Tennessee Clean Water Network (TCWN). 

The Solution

Clear Chattanooga includes major upgrades and revisions to portions of the wastewater system including pipe rehabilitation, pump station improvements, upgrades to the Moccasin Bend Wastewater Treatment Plant and comprehensive operational audits.

Clear Chattanooga’s Comprehensive 3R Approach:
3R - Restore

Restore

optimal functionality and capacity to the wastewater system.

3R - Repair

Repair

the system and prevent chronic overflows.

3R - Replace

Replace

aging infrastructure that is beyond good use.

Clear Chattanooga’s 3R approach is being managed in two major phases.

Phase 1 involves the rehabilitation of high-priority wastewater pipelines, upgrades to pump stations, reliability and capacity improvements to the wastewater treatment plant and the installation of high-priority equalization stations in areas with recurring SSOs. These stations will temporarily store the excess wastewater and stormwater following heavy rain events until the system can handle it.

Phase 2 includes the continued repair and replacement of wastewater pipelines throughout the system and the installation of the remaining planned equalization stations.
