SIGNS YOU MIGHT NEED
When You Need A Design
For septic design in Austin's hills or on acreage out US-290, your soil decides what the system can be, so we check it before anything is drawn. Quick check west of I-35: if a spade hits rock a few inches down, plan on an aerobic design.
Any Of These Happening To You?
Building a new home on septic?
Replacing a system that failed?
Adding a bedroom or guest house?
Buying land and need a soil test?
Planning a pool near the tank?
Tell us the address and what's going up, and we'll say what the soil likely means before a line is drawn.

Design And Permit, One Job
What a Septic Design Includes
Septic design in Travis County means a plan sized to your soil that the permit office can sign off on. We handle the soil, the layout and the permit as one job, and because it's part of all our home septic services, we can maintain the system once it's in.
About three in four new Travis County permits are aerobic, because thin soil or tight clay leaves no room for a drainfield. When your lot can take conventional, we design it that way.
When You're Changing a System You Already Have
A new bedroom or a failed field can mean the old design no longer fits. Tell us what you know about your current system, and have its as-built septic plan handy if you kept one. We'll sort out what the new design needs from there.
How It Works
From Test Holes to an Approved Plan
01
Evaluate The Site
The septic site evaluation starts with test holes where the system will sit, because soil has to be seen, not guessed.
02
Read The Soil
A licensed evaluator classifies the soil from the test holes, and that septic soil test shows which systems your lot can take.
03
Draw The System
We size the system to your home and lay it out around the rock or clay and the setbacks, so it fits before anyone digs.
04
Handle The Permit
The plan goes to the office your land answers to, and we handle the permit there, so you aren't left chasing a reviewer.
WHAT TO EXPECT
What Sets Your Design Price
No two lots take the same work: the soil, the setbacks and the office reviewing the plan all change what a design involves. Call us about your address, and we'll explain what yours needs.
Your soil
Two feet of usable soil is the line. Less in the test holes, and the design goes aerobic, which changes the drawing more than anything else.
Your office
Several offices review plans here, and the one over your land sets what the drawing includes. On the Edwards recharge zone, that adds a geologic assessment.
Your lot
Setbacks from the house, a well, a pool or a second dwelling shape the layout. A tight lot takes more drawing than an open one.
The Ground In Travis County
The Ground Decides the System
If your land is west of I-35, along the Balcones line, you're likely on thin soil over limestone. That's why septic system design around Lakeway and Bee Cave usually ends in an aerobic unit with spray heads.
East of I-35 it's the opposite. Around Del Valle and Mustang Ridge, Houston Black clay drains so slowly the state rules out a standard drainfield, so we design a treatment unit feeding a buried drip field (drip dispersal with secondary treatment, in the rulebook).
What the Edwards Recharge Zone Adds
If your land sits over the Edwards Aquifer recharge zone, the rules are tighter: at least an acre per home, extra distance between the system and any sinkhole or fracture, and a geologic assessment. Any of those can move where the system sits, so we leave room for it from the first sketch.
Which Office Reviews Your Plans
The address picks the office. Unincorporated land goes to Travis County TNR, Austin Water takes the city and Lake Austin frontage, the LCRA reviews land near Lake Travis, three cities run their own programs, and the Hays towns follow Hays County septic rules. We work out which one is yours at the start, so the plan is drawn for it.
Near Lake Travis, LCRA's resale inspection rule explains what a future sale means for your system.
