How It Works

1. Submit Your Property Information
Provide your property address, and any available documents such as a survey or site plan.

2. Site Evaluation & Project Review
We evaluate your property, soil conditions, and project needs to determine the most suitable system.

3. System Design & Permitting
We prepare a code-compliant septic system design and handle the permitting process with the appropriate county.

4. Permit Approval
Once approved, the county issues a permit for installation.

5. Installation by a Licensed Installer
After the permit is issued, a licensed installer can construct the system according to the approved design.
