A routine pump-out of a 1,000 to 1,500 gallon tank in Greater Cincinnati and Northern Kentucky typically runs about $300 to $650. National 2026 cost guides put the average near $420. Buried lids, after-hours calls, extra compartments, and larger tanks push the price up.
More detail
Tank size is the first thing that moves the price. This Old House, using Angi data updated in May 2026, lists $225 to $400 for a 1,000-gallon tank, $275 to $500 for 1,250 gallons, and $345 to $600 for 1,500 gallons, with a national average of $420; HomeAdvisor's June 2026 guide runs higher, at $325 to $700 for 1,000 gallons and $450 to $1,100 for 1,500 gallons, with an average of $428. Use those bands as a sanity check on a local quote; a few regional costs explain where in the band it lands. Every load has to be unloaded somewhere, and the Metropolitan Sewer District of Greater Cincinnati charges haulers $8.00 per 100 gallons in 2026, so disposal alone is about $80 on a 1,000-gallon tank; Sanitation District No. 1 in Northern Kentucky lists a sludge dumping charge of $119 per 1,000 gallons. Clermont County's Regulation 415 does not permit land application of septage anywhere in the county. Access is the second driver: national guides add $50 to $200 when a tank is hard to find or reach, and a tank without risers means digging on every visit. Timing is the third, with after-hours or emergency calls running 50 to 100 percent above standard rates. Newer Ohio tanks for three or more bedrooms have two compartments, and a pump chamber adds another line. To keep the cost down without cutting corners, pump on schedule rather than waiting for a backup, install risers once (HomeAdvisor lists them at $300 to $600) so no future visit includes digging, book in fall before frozen ground slows access, and skip bacteria additive upsells, which Ohio State University Extension calls unnecessary and no substitute for pumping. Ask for an itemized quote that lists tank size, gallons, disposal, and any add-ons so two quotes can be compared line for line.
