Installing a new septic system is one of the most important investments you'll make in your property. Done right, it will serve your home or business reliably for 20 to 30 years or more. Done wrong, it can mean costly repairs, failed inspections, and potential health hazards.
Walls Excavation and Septic handles every step of the installation process — from soil evaluation and system design through permitting, excavation, installation, and final inspection. We work with conventional gravity-fed systems and pressure-dosed systems, selecting the right fit for your site and soil conditions.
We serve homeowners, builders, and developers throughout Coffee, Franklin, Moore, and Bedford counties. Whether you're replacing a failed system or installing on a new lot, we'll design a solution that meets state and county requirements and fits your site.
What's Included
Frequently Asked Questions
How do I know which type of septic system I need?
The right system depends on your soil type, lot size, setback requirements, and local regulations. We perform a soil evaluation and perc test to determine what will work on your specific site, then design accordingly.
How long does a new septic installation take?
Most residential installations take 1 to 3 days of on-site work once permits are approved. Permitting typically takes 2 to 6 weeks depending on the county. We handle the permit process and keep you updated throughout.
How long will a new septic system last?
A properly installed and maintained septic system typically lasts 25 to 30 years or more. Regular pumping every 3 to 5 years is the single most important thing you can do to extend its life.
Can you install a system on a lot with poor soil?
Often yes. Mound systems and pressure-dosed systems are designed specifically for sites with slow-draining or shallow soils. We will evaluate your lot and walk you through the available options.
