Professional Septic Tank Installation Across Marshall & Blount Counties
New construction and failed-system replacement require an approved site, design, permit, excavation plan, installation, and inspection sequence. Stephens Septic can review the project and confirm which parts of that sequence the crew will perform or coordinate before providing an estimate.
A new septic installation is a coordinated site, design, permitting, excavation, and inspection project. The correct system cannot be selected from bedroom count alone; property conditions and the applicable county health-department process determine what can be approved and built.

When Is Installation the Right Next Step?
Use these service-specific conditions to decide whether to request this work or start with a different diagnosis:
- New construction will not connect to a municipal sewer.
- A documented system failure cannot be corrected with a component repair.
- A property change requires a new or revised approved onsite system.
- The owner needs help understanding the sequence from site evaluation through installation.
What Changes the Scope or Estimate?
A useful estimate starts with the property, access, symptoms, and requested outcome. These are the service-specific factors Stephens will need to understand:
- Approved design, tank capacity, distribution method, and drain-field layout
- Site access, clearing, excavation, material, and restoration needs
- County review, permit, and inspection timing
- Existing utilities, structures, setbacks, and the condition of any system being replaced
What to Share Before the Appointment
Collect the property survey, building plan, bedroom count, prior septic records, and any county correspondence. Do not schedule excavation until the required site and permit steps are clear.
What this page cannot determine
Stephens should confirm its exact responsibility for design, testing, permits, inspections, and restoration in the written estimate. Timelines and prices vary too much by approved system and property to promise from a generic webpage.
