Equalization Stations
Decreasing the Sanitary Sewer Overflows (SSOs) is among Clear Chattanooga’s goals. SSOs occur during heavy rain events when there’s not enough storage capacity in the City’s wastewater system to handle the wastewater and increased amount of stormwater. SSOs are a significant environmental and public health risk.

Equalization stations create capacity, prevent overflows and help equalize the flow through the system. The stations will temporarily store the excess wastewater and stormwater until the system has the capacity to handle it. These facilities are generally emptied within 48 hours.

Many factors go into selecting the site for an equalization station.

Connection access to the large sewer pipes underground
Close proximity to the overflow locations to help prevent Sanitary Sewer Overflows
The site cannot be in a Flood Zone.
Terrain suitable for construction
Hamm Road Equalization Station

Hamm Road Equalization Station

Construction on the Hamm Road Equalization Station project began in Spring 2019. The project is designed to address SSOs in the area including the West Bank of the Tennessee River the near Moccasin Bend Wastewater Treatment Plant. A total of three stations will be built at this location..
