About the Service

Septic System Replacement & Installation, Done Right

The right septic design depends on the home, the soil and the site. A soil evaluation decides what is allowed and what will work: a traditional trench system, a mound system, a drip distribution system or an aerobic system. We dig, set the tank and build the field to the approved design.

We coordinate with the county or state permitting process and the soil professional, and we protect the drain field area during construction. Our free Septic System Planner gives you a first look at what to expect.

Music City Excavation brings septic system replacement & installation to homes, farms and businesses in Nashville and across 16 Middle Tennessee cities.

Good to Know

Questions About Septic System Replacement & Installation

Still have a question?

Call 615-357-7797

How do I know which system I need?

A soil evaluation by an authorized professional decides what is allowed on your site. We work with that design and explain the options.

Do I need a permit?

Yes. Septic systems are permitted through state and local authorities, and we help with the process for your county.

How long does a septic system last?

It depends on the system, the soil, the use and the care. Pumping regularly and protecting the drain field help.
