WHAT YOU SHOULD KNOW ABOUT
Commercial Septic Design
What Kind Of Septic System Will Best Fit My Business?
The short answer for the local conditions here in the Hill Country is that an aerobic septic system will likely be the best fit for you and your business needs. The longer answer is that if you get in touch with us, our goal is to design the right system — aerobic or conventional — that fits your current and future business needs, your property size and access, water table factors, state and local codes, and a whole list of other things.
We're your professional septic design team, and our job is to get you a system you'll be happy with now and down the road.
How Long Should My Commercial Septic System Last?
It truly does depend! If your employees and customers do their part by not flushing stuff they shouldn't, and if you have a solid regular maintenance plan in place — with regular pumping, inspections, and upkeep — your system can realistically last 20+ years depending on usage. But if you skip the proactive care, how long it lasts becomes a lot less predictable.
Our Commercial HomeField Advantage Plans are designed to make the whole maintenance thing easy for you (and easy on your budget).
How Much Space Will My Commercial Septic System Need?
There's no cookie-cutter answer to this one. A lot of factors go into the square footage of your system's design. Aerobic systems (which are the most common here in the Hill Country) typically take up less space than conventional systems — that's one of the perks.
How much you plan to use your system, your soil and property layout, and your future growth plans all factor into how big your system needs to be. Give us a call and we'll get you a detailed estimate for your specific property.
How Much Will My Septic System Cost To Install?
Once you've got the perfect commercial septic system designed, it's time to get it in the ground. From a cost standpoint, think of it like buying a new vehicle for your business. The type of system, the size of your tank and drain field, and how easy it is to get to your property are all major factors in the final installation cost.
When it comes to septic, there really is no one-size-fits-all price. Give us a call and we'll work with you to find a solution that makes sense for your business and your budget.

Super friendly, super professional! This will be the only company that I ever use again. They are honest, hard working and very knowledgeable. #1 in my book.
Had a septic issue and they were the only company able to make it out the next day. Highly recommend this company. Really friendly and knowledgeable.
Love the service of this company! Very professional and the people are so knowledgeable and nice. Would recommend their services to anyone.
They came out to our property to diagnose why the alarm was going off. They fixed the problem and educated me on best practices. I highly recommend their services because of their friendly professionalism and expertise!
I’ve been extremely satisfied with their service. I’m a monthly service plan member and recently had an issue with my aerobic system on a Friday afternoon. I called and was impressed with the speed of getting a technician onsite to repair my system. They communicated via SMS in a very timely manner and resolved my issue very quickly. Highly recommend!!
Love love love this company!! They always have done a great job!! Very knowledgeable! They always get the job done! They are reliable and very honest! I could not recommend them more!! Great company! Thank you!
We have a service contract, and everyone we deal with has always been so helpful. They are quick to respond, and help us learn about our system.
I am a professional builder and Brian is the best. He is fair in his pricing and he does an excellent job from design to installation. You can rely on Brian for a trouble free construction experience.
Excellent service, in a timely & professional manner, at a fair price. They have excellent service for our aerobic system with a yearly contract at a fair price. Definitely recommend to anyone. A company you can count on consistently!
Showed up on time…in the middle of a severe storm and performed the work anyway. The young man had a positive attitude and the rain didn’t seem to phase him. Nasty conditions but performed like it was a beautiful sunny day. He took photos like I asked and documented the process. Thank you for your professionalism
Wonderful customer service, came out and fix the problem on the septic system and gave me a quick training on how to maintain good working order. Thank you for your excellent customer service!
These guys are real professional. They know their stuff. They even suggest ways that you can make your septic tank last longer and work more efficient. I will recommend them as the best septic tank company that I have ever used!!
I had an issue with my aerobic system at my home in Cedar Hill and called them at 8am. They came and had my issue fixed shortly around noon. I signed up for their annual maintenance service at a very reasonable price.
I called on the 16th of January in the midst of a hard freeze due to my septic system alarm going off. Even with the weather and its associated workload, the techs arrived the same day and resolved the issue. Awesome service seems to be the norm for this company and their techs!
Great service. We received service within a few hours of calling in. They came in and found the issue immediately and provided great tips and feedback. We know nothing about the septic tank so the info gathered was very helpful.
OUR PROCESS
The Game Plan For Your Septic System Design
Designing your commercial system means discovering what your septic needs are (and will be), matching that with the right type of system, to making it all to code
Location. Location. Location.
We’ll visit your prospective septic site to take a deep dive into its topography, soil type, soil permeability, and a host of other factors
Determine Your Needs
We look at household size, expected water usage, and also your potential future needs to calculate your septic tank and drain field sizes.
Find The Right Type
Based on your expected usage, soil conditions, space available, and local regulations, we’ll help you land on the right system type and size.
Design The Right Layout
We’ll find the perfect place to put your septic tank, drain field, and additional parts of your system for correct flow and max accessibility.
Permits And Approvals
Once your system is designed and approved by you, we need to submit it to your local authorities for review, permitting, and code compliance.
