Frankfort's first wastewater treatment plant was originally constructed in 1955-57 with grit removal, primary settling basins, a sludge thickener and two-stage anaerobic digestion with sludge drying beds. Chlorine was used for disinfection prior to discharge into the Kentucky River. In 1978-80, a new secondary activated sludge "oxidation ditch" type wastewater treatment plant was constructed and the disinfection process was changed to Ozone, which is more efficient and environmentally safe. This was a state-of-the-art design, and the first of its kind in Kentucky.

The recent 2001 expansion increased the plant from a 6.6 MGD (million gallons per day) facility to a 9.9 MGD facility. This increase provides additional capacity to serve the needs of the Frankfort community for the immediate future.

The Sewer Department currently has a Long-Term Control Plan for its Combined Sewer System (CSO) and a Sanitary Sewer Overflow Plan (SSOP) for its Sanitary Separate Sewer System. Both of these programs will require large expenditures to meet Federal and State regulatory requirements.

It is illegal to connect a storm water drain, downspouts, foundation sump pump, or any other storm water to a separate sanitary sewer. Any person, firm or corporation connecting surface or subsurface storm water to a separate sanitary sewer shall be guilty of a misdemeanor and, upon conviction, shall be fined.

NOTE: Although there is no extra charge for our service (work is financed by sewer bills), we will not assume the cost of your contractor's call, regardless of the location of the stoppage.

The City of Frankfort Sewer Department has a fats, oils and grease (FOG) program to reduce the amount of these materials entering our sewer system. FOG can cause backups in your lateral lines or in the Sewer Department mains that can send sewage into your home or business. For more information on the Sewer Information link to the right, then look for the FOG Program.
