Septic Design & Engineering in Inola, OK
Every dependable septic system in Inola begins with a plan built on measurable site data instead of guesswork. Martin Septic evaluates your soil, your lot dimensions, and your household demand before recommending any system type. Our crews are DEQ certified for both aerobic and conventional systems, so the design you receive matches your land rather than a sales pitch. Rogers County ground carries heavy clay in many areas, and that reality shapes which systems will actually perform here. We handle the soil testing, the sizing calculations, and the permitting paperwork so you never have to navigate state requirements alone. A design from Martin Septic accounts for setbacks, drainage patterns, future construction plans, and the layout of your entire property. Because we install the systems we design, our plans are practical and buildable, never theoretical drawings that fall apart at excavation. You get honest recommendations from professionally trained crews who explain the reasoning behind every single choice. Our membership in the Tulsa Home Builders Association keeps us connected to local construction standards and the needs of new development. Estimates are always free with no obligation, so getting real answers about your Inola property costs you nothing.

Customer Testimonials
A contractor that does what he says, always answers the phone, and extremely fair pricing. You can’t ask for better than that.
Had a major issue with my aerobic septic system. They came out the same day, got my system working great for a good price. Super nice, even gave some things to try over the phone before they came out. A week later, had a sprinkler bust and they came back and fixed it at no charge. Would def recommend.
They are an amazing company. They are honest and very fair on prices. You have a lifelong customer.
Have used him multiple times and always takes care of us. He is the only one we will call about any septic issues
10/10—highly recommend! They sent me a same-day quote and got us on the schedule super quick. They installed our in-ground storm shelter and worked on our aerobic system. They showed up on time, cleaned everything up afterward, and were both super friendly and professional throughout the entire process. They also beat every other quote we received. It’s rare to find both top-quality work and great pricing—these guys are both!
I recently contacted Martin Septic and was impressed from the beginning. Now, after meeting the crew, watching them work, answering all my questions and paying the bill, I highly recommend them to everyone!! Professional, honest, hard working and staying in constant contact was so important and followed through until the end. Great company and so glad I choose them!
We had a great experience with Martin Septic in Inola! When we woke up and realized we had a problem, they responded almost immediately and were out to us much faster than we expected! Same day service is so rare these day. Much less to make the call and have help within a few hours. They were extremely knowledgeable and took the time to explain what was going on and what needed to be done. It never felt rushed or confusing. They were friendly, respectful, and easy to work with the whole time and that meant so much to us! It may sound cliche but what impressed us most was how much they genuinely cared about doing the job right. They went above and beyond to make sure everything was handled properly before they left and that all our questions were answered. You can tell they take pride in their work. We would absolutely use them again and highly recommend Martin’s Septic to anyone!
I was having trouble with my high water alert and called Martin Septic. They were extremely helpful, answered all my questions, showed up when they said they would and fixed my issue quickly. I will absolutely be using Martin Septic in the future.
Quick response. Work done timely and properly. He was highly recommended and didn’t disappoint.
Very prompt to reply after I texted. I called Josh on a Friday and he came out within an hour for an inspection. He was in contact before he left my house with PrimeFlo to have the septic tank pumped out and they actually called me within 10 minutes to service my tank on the same day. I also like that they are a family business and local to my hometown.
Very responsive, knowledgeable and finished job on time. They were very easy to deal with and friendly. I highly recommend using their service.
Josh and his grew did an outstanding job for us on new septic system. Would highly recommend if you are in need of any septic problems!
They did a great install for a customer I referred them to on a new house! Reliable and affordable
Martin septic is reasonably priced, his quality of work and attention to detail is top notch. I definitely recommend his work for future projects.
Josh is one of the most honest businessmen I know! He takes great pride in his work and treats his clients like family. He’s always my GO TO person when I have septic questions!! I highly recommend Martin Septic!!
Martin Septic LLC is my go-to crew for NEW septic installs — and I wouldn’t trust anyone else to bury thousands of dollars in the dirt for me. I build homes for a living, so I deal with a lot of sub-contractors… and let’s just say some of them couldn’t find their own toolbox with a map. Martin Septic is the complete opposite. These guys show up on time, do clean work, and install new systems like they’re assembling high-end plumbing Legos. Their communication is solid, the work is efficient, and the jobsite is always left looking like professionals were actually there — not raccoons with excavators. Every install I’ve had them do has been smooth. No drama, no surprises, no “hey man, we’re gonna need another $2,000 because the moon is in retrograde.” Just clean, reliable work. If you need a new septic system installed in Inola or anywhere nearby, call Martin Septic. They make the dirty jobs easy — and make me look good as a builder. Five stars. They get it done.
Josh came over and found a leak in our septic lines and replaced it. He was quick to respond and was very professional. I highly recommend him!
They have done a great job every time we have used them. Professional, competitively priced, and easy to work with. Highly recommend.
Josh and his team are great, honest, and very knowledgeable. Josh is super friendly and answers all your questions. He's a pleasure to do business with. Highly recommend.
The team at Martin Septic is awesome! Super friendly & honest! Definitely recommend!
Josh and his team work as hard as they can until the job is finished the right way!
Our family is very grateful for the hard work and diligence that Martin Septic provides. Their honesty and kindness surpassed our expectations and we can’t thank them enough for what they do and how they do it!
Josh Martin installed an aerobic system for us. He communicated well with us was responsive to any attempts we made to make contact with him, He was very Informative it was a parent that he knew what he was talking about. He was timely and presented when he said that he would. He completed the job in a timely fashion and was in general a very pleasant person to deal with. But what impressed me the most is that when he showed up at our home, he had his teenage daughter with him. This young lady was present the entire time during the two day job, Worked hard and helped where she could. I personally think it’s important for children to understand how hard their parents work for the things they have And where the money comes from.
Excellent service. Great communication. Very easy to do business with and great work.
We've had outstanding service from them, twice! They installed my father’s shop septic system, so we reached out to them when our lender requested a last-minute septic inspection for our home purchase. From the initial phone call, Josh was particularly helpful in explaining the process, answering my questions, and quickly providing us with our inspection report. We look forward to using Martin Septic to help us maintain the system and highly recommend them for all septic needs!
I would recommend 100x over. They are extremely professional, their communication is spot on and they do quality work. Give them a call and see for youself!
Josh and his daughter installed an aerobic system at my house a few days ago and did a great job! Super helpful people and quick.
He came out on a Saturday and not only fixed the problem but took the time to checkout the entire system! I would highly recommend for any of your septic needs!
After the May tornado I had an estimate by another company but wasn’t pleased with the options they gave so I found Martin septic and called him he came out gave me a new estimate with the option I was hoping for and was here and work was completed within a few days saving me thousands of dollars. So nice and kept me updated through out the whole repair. I’m pleased with his thorough job and the information provided to me.
Would highly recommend and use again. To this day he will still reply back to any questions I have. The rock they encountered didn’t stop them from completing the job.
Josh and his team couldn’t have been more professional. We needed work done fast and he came through with flying colors. His prices were very competitive and the work was done to perfection. Thanks for the hard work we couldn’t be happier. The Smiths
Great customer service, knowledgeable and all around awesome to work with!
Would recommend 365/365! Josh and his crew drove an hour and a half to get me out of a bind to get my aerobics system put in! Called for advice on a few trouble shooting issues and he walked me through them on the phone! When my plumbers messed up and dug out my line he came in and put a new pump in! Great work and great dude!
These people are the best to work with. They got my septic done so fast. Their price was amazing too
Prompt, courteous, and professional are just a few words I'd use to describe my experience with Martin Septic. Josh and his team are fantastic.
10/10 would recommend this crew they are extremely knowledgeable and honest!
After our home inspection process on a home purchase, my wife and I were informed that the septic was outdated and it needed to be replaced. Mr. Joshua Martin was hired to completely replace and install an Aerobic septic system. It was installed professionally and on time for our closing. His communication about the process was appreciated. Highly recommend supporting local 👌
Highly recommend Martin Septic for any Septic system issues. Professional, timely, and helpful service.
We called Martin septic for pump out service. We try to use local businesses when possible. Josh was very responsive from the first contact. He followed up within a few days and the job was completed to our satisfaction. He is a very friendly and a hard working young man. He cleaned up the site after the service. This is not a pleasant job, but he is knowledgeable and professional.

Septic System Design & Engineering
Septic design and engineering is the planning discipline that determines how an onsite wastewater system will collect, treat, and disperse everything your household sends down the drain. The work happens before any equipment is purchased and before a single trench is opened, which is exactly why it carries so much weight. A qualified designer studies the property in person, measures the available space, evaluates the soil at the proposed field location, and estimates the daily wastewater flow the home will produce. Those findings become a documented plan showing the system type, the tank capacity, the treatment components, and the precise layout of every line on the lot. Oklahoma requires this level of planning because a failed system contaminates groundwater, damages neighboring property, and creates health hazards that spread well beyond one yard. Around Inola, where clay soil and rural acreage shape most projects, careful design separates systems that last twenty years from systems that fail in five. Martin Septic approaches design as an engineering problem grounded in measurable data, never as a formality to rush past on the way to excavation. Every calculation is documented, every assumption is checked against site conditions, and every plan is built to pass DEQ review the first time.
Soil evaluation sits at the foundation of every competent septic design, because soil performs the final stage of treatment in a conventional system. A profile analysis examines the layers beneath the proposed drain field, recording texture, structure, color patterns, and the depth to any restrictive feature. Evaluators look specifically for seasonal groundwater indicators, bedrock, and dense clay pans, since each one limits how effluent can move through the ground. The results establish a soil application rate, which is the single number that controls how many square feet of absorption area your system requires. Ground around Inola ranges from workable loam to tight clay that accepts water slowly, and two lots on the same road can test completely differently. Slow soils demand larger absorption fields, shallow groundwater forces alternative designs or shallow placement, and some sites rule out conventional lateral lines entirely. Ignoring these realities does not make them disappear; it simply schedules a failure for a few years after installation. Martin Septic tests where the field will actually go, documents the findings for DEQ, and explains in plain language what your land can support.

Why a Licensed, DEQ-Certified Septic Designer Is Important
Septic design in Oklahoma is regulated for good reason, and DEQ certification proves a designer has been trained and tested on those regulations. An uncertified designer can hand you a plan that looks professional and still fails state review, wasting weeks of your construction schedule. Certification means the person planning your system understands soil application rates, setback rules, and sizing formulas exactly as DEQ enforces them today. It also creates accountability, since certified professionals answer to the state for the quality of their work. Inola properties often sit on clay soils where the margin for design error is thin, and only a trained evaluator can read those conditions correctly. A DEQ certified designer knows when a conventional system is viable and when an aerobic unit is the honest answer. Mistakes in this trade contaminate groundwater, spark disputes between neighbors, and create genuine health hazards for families. Certified design work protects your property value by producing a documented, approved system that survives inspections and appraisals. Martin Septic carries DEQ certification for both aerobic and conventional systems, backed by professionally trained crews who give straight answers to every customer. Hiring certified expertise in Inola is not a luxury; it is the difference between a system that lasts and a liability buried in your yard.
