Building a home in West Texas or replacing an old septic system? You’ve probably heard about conventional and aerobic systems. Each has its advantages, but a lot of the decision comes down to the soil on your property.
Here’s a quick breakdown:
🔹 Conventional systems
These use a septic tank and an underground drain field with pipe and gravel or leaching chambers. They’re simple, usually cost less to operate, and gravity systems don’t need electricity. The downside? They need suitable soil and enough room. Heavy clay or shallow rock can rule them out.
🔹 Aerobic systems
These use oxygen to help treat wastewater. With a spray system, the water is disinfected before going out through spray heads. They can be a good option where a conventional drain field won’t work, but they require electricity, regular maintenance and inspections. There are also more moving parts to repair over time.
Just because your neighbor has one type doesn’t mean it’s the right choice for your place. Soil can change from one property to the next. Soil depth, slope, available space and local requirements all play a part, too.
A soil and site evaluation is the starting point. From there, you can choose a system that fits your property and understand what it’ll take to maintain it.
