How a New System Gets In
A septic system is decided by the ground it sits on, not by a catalog. Here's the order it actually happens in.
-
Soil & Site Evaluation Before anything is designed, the ground gets tested. A site and soil evaluation is the first line on the list for a reason: it decides what a lot can actually support.
-
Design & Permit The soil results decide the design, conventional or aerobic, and where it sits on the lot. The paperwork goes in before a shovel moves.
-
Tank Poured at Our Yard Most installers buy their tanks from a supplier. Wilton Krause Septic manufactures its own concrete septic tanks, so the tank that ends up in your yard was poured at theirs.
-
Install & Final Inspection The tank and lines go in, get backfilled, and the system goes through its final inspection.

Where We Work
Wilton Krause Septic serves seven counties: Guadalupe, Wilson, Bexar, Comal, Caldwell, Gonzales, and Hays. Out past the New Braunfels city line, most of this ground runs on well and septic, not city sewer, and the system has to match the soil it sits on.

Septic Questions, Answered Plainly
What does a septic system do?
It treats and disperses the wastewater from a home that isn't on a city sewer line. Solids settle out in the tank, and the liquid that's left drains out through a drain field into the soil.
How does a soil evaluation decide what system I need?
Different soils drain at different rates. A soil evaluation tells an installer whether a lot can support a standard system that relies on gravity and the ground, or needs an aerobic system that treats the wastewater further before it ever reaches the soil.
Can heavy rain affect my septic system?
Heavy rain and snowmelt can saturate a drain field and slow how fast it absorbs wastewater, which is part of why a system has to be built for the actual ground it sits on, not a generic lot.
What's the difference between a conventional and an aerobic septic system?
A conventional system relies on gravity and the soil itself to treat wastewater. An aerobic system adds a treatment step before the water reaches the drain field, usually where the soil can't do that work alone.
