Septic tank pumping in Auburn is mostly for homes outside the reach of the Auburn Sewer Department, which the state's water resource database credits with about 741 serviceable households in and around town. Auburn sits at 642 feet on the sinkhole plain that covers the southern half of Logan County, so septic systems here need to work. Tell us whether your Auburn home is on sewer or septic and we will follow up by phone.

Auburn-area homes can use each of these services, depending on sewer or septic:
The Kentucky Geological Survey describes the southern half of Logan County as a sinkhole plain at about 600 to 650 feet, set apart from the higher, hillier north by the Dripping Springs Escarpment. Its Logan County karst page warns that sewage entering a karst aquifer is not filtered.
In town, the Auburn Sewer Department runs a treatment plant that discharges to Blacklick Creek and serves 864 customers, 782 of them residential, according to the state's water resource database. The same database lists plans to replace a stretch of old gravity sewer on West Main and Roosevelt streets and to fix 14 failing lift stations.
The state's water resource database lists 1960 as the year the Auburn Sewer Department was established, and its treatment plant is designed for 0.350 million gallons a day against an average daily flow of 0.199 million gallons. Besides its 782 residential customers, it serves 65 commercial, 16 institutional and 1 industrial customer. Over the year the database reports, the plant treated about 86.5 million gallons, and the city's approved facility plan, last revised in 2018, is listed as about 80 percent built.
The plant discharges under a state permit issued in June 2026 that runs through July 2031. The West Main and Roosevelt Street project covers old pipe serving nearly 20 customers and aims to cut the inflow and infiltration that send extra water to the plant, and a separate plan addresses the failing lift stations to prevent sewer overflows.
The 2020 Census counted 1,589 residents and 710 housing units in Auburn, and the Census Bureau's survey puts the median home's build year at 1967. Many Auburn house lines are therefore decades old, which is why a camera run is worth doing before a sale. The Auburn Historic District was added to the National Register in 1994.
Logan County's landscape sets the stakes. The Kentucky Geological Survey says streams on the southern sinkhole plain are cut about 50 to 75 feet below the surface, and that the Dripping Springs Escarpment rises 150 feet above the plain to about 750 feet. By its 2008 estimate, 99 percent of Logan County residents were on public water, up from 80 percent in 1999, and Russellville, the county seat where septic permits are handled, sits at 595 feet.
At the other end of the county, the Mud River drains the northwestern part of Logan County and leaves it at about 395 feet, the county's lowest point.
Auburn sits on US 68 and KY 80, which also run as bypasses around town, with KY 103 and KY 1039 reaching into the countryside. McCutchen Meadows, a National Register property, lies off US 68.
The Auburn Historic District runs roughly along East and West Main, North Lincoln, Perkins, Pearl, Caldwell, Wilson, Maple and Viers streets, and the 42206 ZIP code reaches into Simpson County as well as Logan.
