What is an overflow vs. a release?

The City of Franklin received an updated NPDES permit that became effective July 1, 2017 that defines a difference between a release and overflow.  In each below definition, the permittee is defined as the City of Franklin.

Release: the flow of sewage from any portion of the collection or transmission system owned or operated by the permittee other than through permitted outfalls that does not add pollutants to waters.  In addition, a release includes a backup into a building or private property that is caused by the blockages, flow conditions, or other malfunctions originating in the collection and transmission system owned or operated by the permittee.  A release does not include backups into a building or private property caused by blockages or other malfunctions originating in a private lateral.

Overflow: an unpermitted discharge of pollutants from the collection or transmission system owned or operated by the permittee other than through a permitted outfall, and reach receiving waters. 

For either situation, the discharge of wastewater can be attributed to the following causes:

  • Blockages of sewer lines often due to grease, rags, or other materials wrongfully put into these sewer lines.
  • Infiltration/inflow of excessive stormwater into sewer lines during heavy rainfall.
  • Malfunctions of pumping stations, either equipment, or electrical outages.
  • Broken sewer lines, caused by construction, line failure, or geologic conditions.

The City is required to initially notify releases and overflows to the Tennessee Department of Environment and Conservation within 24 hours. Basic information will be reported here within two (2) business days of the event.
