We take on the permit so you don't have to, keeping your project moving and keeping you in control.

Types of Septic Systems We Install

Tennessee's varied soil conditions, from the red clay of Loudon County to the rocky terrain of Morgan County, require different system types. Clear Flow installs:

  • Conventional Gravity Systems, The most common type for lots with adequate soil depth and percolation rates.

The Septic Installation Process

1. Site Evaluation & Soil Testing

We visit your property to assess soil conditions, lot size, and setback requirements. For lots under five acres, TDEC typically requires a perc test performed by a licensed soil scientist. We coordinate this for you.

2. Permit Application

Clear Flow handles the TDEC permit application. We submit the required documentation, pay the permit fees on your behalf (reimbursed at project start), and track approval status. Most permits are approved within 2–4 weeks.

3. Excavation

Once permitted, our excavator opens the tank pit and drain field trenches to the precise dimensions required by your permit. We work efficiently to minimize disruption to your property.

4. Tank Placement & Drain Field Installation

We set the concrete septic tank, connect the inlet and outlet pipes, and install the drain field chambers with the required gravel bed. All work meets or exceeds TDEC specifications.

5. Inspection & Backfill

The county inspector reviews the installation before we backfill. Clear Flow coordinates the inspection appointment and is on-site to answer any questions.

6. Final Walkthrough

We walk you through the completed system, explain maintenance requirements, and provide documentation for your records.
