30 years.
One owner. Same number.

Ray Pennington has been pumping septic tanks and cleaning grease traps across the tri-state area since 1996. Owner-operated from day one — you call, he picks up.

Our story

It started in Dearborn County.

Ray Pennington started Tri-State Liquid Waste in 1996 with a straightforward idea: do honest work, show up when you say you will, and don't leave a mess. Three decades later, that's still the whole business model.

Operating out of 761 W Eads Pkwy in Lawrenceburg, Tri-State serves residential and commercial customers across Indiana, Ohio, and Kentucky — the tri-state area that defines this corner of the country. Homeowners, restaurants, contractors, municipalities — they all call the same number and get the same commitment.

This is an owner-operated business. When you call (812) 537-3888, you're reaching a company where the person making decisions is the same person whose name is on the truck. That means accountability on every job — no layers, no excuses.

How we work

"Dependable liquid waste service — no surprises, no mess left behind."

Four principles we've kept since 1996.

Straight Talk

We tell you what the job costs and what we found. If it needs a repair, we say so. If it doesn't, we say that too.

Owner-Operated

Ray Pennington runs this company. The buck stops with him. You'll never be bounced to a call center or a subcontractor on the fly.

Local Knowledge

We know Dearborn County soil, the regulations in Indiana, Ohio, and Kentucky, and the quirks of tanks in this part of the country.

Reliability

30 years of showing up. Scheduled service, emergency calls, and everything in between — we're there when you need us.

By the numbers

A Lawrenceburg institution with deep roots.
