Thin soil over limestone
Canyon Lake and the Hill Country above the escarpment
Shallow soil on Glen Rose and Edwards limestone leaves little depth for a drain field. Aerobic systems and careful design are common.

I was extremely pleased with the customer service and the work provided by Shawn. Shawn and his wife were very pleasant and friendly! I only asked for a septic tank pump out. Shawn came out and not only pumped out my tank but also inspected it for any cracks. They are definitely my go to now for any septic issues! I highly recommend Christian Septic Pumping!!!

Showed up exactly when they said they'd show and he was very polite. Answered all of my questions and even gave me a short school on how the system works. He made me feel very assured about his work.

Local knowledge
Three kinds of ground, one escarpment.
The service area straddles the Balcones Escarpment. West of it, thin soil over limestone; east of it, deep blackland clay; along it, the springs and the Edwards Aquifer. Each asks something different of a septic system.
02 · The line
The escarpment line
New Braunfels, San Marcos and the Schertz area along I-35
The Balcones faults run right through here. Springs, the Edwards Aquifer recharge zone and stricter septic rules sit along this line.
03 · East
Blackland clay
Marion, Geronimo, New Berlin and Seguin below the escarpment
Deep black clay swells when wet and cracks when dry, and water moves through it slowly. Drain fields here need room, and aerobic spray systems are common.

Straight answers
Septic questions, answered.
How often should a septic tank be pumped in Texas?
For a conventional system, the TCEQ recommends pumping every three to five years. The right interval for your home depends on tank size, how many people live there and how much water you use.
What are the signs my septic system needs attention?
Slow drains throughout the house, gurgling in the pipes, sewage odor in the yard, wet or unusually green ground over the tank or field, and toilets that back up are the common signs.
What is the difference between a conventional and an aerobic septic system?
A conventional system is a tank plus a drain field: solids settle in the tank and the liquid soaks into the soil, which treats it. An aerobic system adds air and bacteria to treat the wastewater before it leaves, then usually sprays or drips it over the yard.
What is the Balcones Escarpment, and why does it matter for septic?
It’s the line of faults where the Texas Hill Country drops to the coastal plain, running past San Marcos, New Braunfels and the San Antonio area. West of it the soil is thin over limestone; east of it, deep blackland clay.
What is an effluent filter, and how often should it be cleaned?
An effluent filter sits in the tank outlet and stops solids from leaving the tank and clogging the drain field. Most need cleaning at every pump-out, and some households need it more often.
Do I need a septic inspection when buying a house in Texas?
Texas has no statewide rule requiring a septic inspection at sale, but buyers, lenders and agents often ask for one, and it’s worth doing.
