All servicesIn their own words
“We are a Christian-based business that values integrity, quality, and honesty.”
Larry started the business “on Godly principles with honesty and integrity at its core.” The family company still describes itself the same way.
Competitively priced work with the price up front. That’s been the promise on every page they’ve published.
Site evaluator, Installer II and maintenance provider licenses under one roof, so the same company can evaluate, build and maintain a system.
Larry Goodwill put his name on the business in 1993. The family company still carries it, and answers to it.

Reviews
Word for word, from Google reviews shown on Larry’s own website.
First time using a septic service. Cody was amazing and knocked our aerobic system out in 1 day. Communication was great and guided us in the right direction with an engineer and the permits. I won't be calling anyone else.
We worked with Cody on a new septic system installation. He was communicative and honest throughout the planning and preparation and executed the project end to end in one day with high-quality results. Would definitely recommend to others!
Such quality service!! Cody was so nice and informative and he showed up right on time. He gave many helpful tips and put us on a service schedule. Would highly recommend!
Office was very friendly and responsive. Jacob was on time and very professional, highly recommend, I will reach out as needed!!
Great experience with Larry’s Tank Service! Showed up perfectly on time, did great work, was super informative, and very professional.
Went with Larry's another time and was very well pleased both times. Very professional vet Small Town friendly. Thank you for getting us out of a bind.
Local knowledge
The septic system you can build depends on what’s under your feet. Around Bastrop that changes within a few miles.
Deep sandy ground under the loblollies around Bastrop and Smithville drains fast. Sometimes too fast, and sometimes onto a clay layer below.
North and west toward Elgin, Manor and Lockhart the soil turns to black clay that swells, cracks and drains slowly. Aerobic spray country.
West of I-35 near Bee Cave and Buda, thin soil sits on limestone over the Edwards Aquifer, and stricter rules apply.
Getting started
Call (512) 212-9821 or text (512) 985-6570. Tell us the system type if you know it, whether the lid is exposed and whether a truck can reach it.
A licensed tech checks the tank, the field and, on aerobic systems, the compressor, pump, chlorinator and sprinklers.
You hear what we found and what it costs before we start. No hidden fees.
Pumped, repaired or built to Texas OSSF rules, with the paperwork your county or city needs.
Straight answers
For a typical conventional system, every three to five years. That’s the TCEQ guideline and the interval Larry’s has recommended for decades.
Slow drains, gurgling pipes, sewage odors inside or outside, soggy ground or standing water over the field, unusually green grass over the field, sewage backing up, or an alarm going off.
An aerobic system pumps air into the wastewater so oxygen-loving bacteria break it down far more than a plain septic tank. The treated water is disinfected with chlorine and then sprayed or dripped over a lawn area.
The soil finishes the treatment. It has to accept water at a steady rate and filter it before it reaches groundwater.
Texas doesn’t have a statewide rule requiring one at every sale, but you should get one. Lenders and buyers often ask for it, and a standard home inspection doesn’t open the tank or test the field.
The Texas Commission on Environmental Quality (TCEQ) sets the rules for on-site sewage facilities (OSSFs) in 30 TAC Chapter 285 and licenses the people who work on them. Local authorized agents, usually the county or a city, issue permits and inspect.
