Georgia's OSMS Regulatory Framework
Georgia regulates onsite sewage management systems under the Georgia On-Site Sewage Management Systems Law (O.C.G.A. 31-2A-7 and 31-7) and Georgia EPD's rules at Chapter 391-3-5. The Georgia Environmental Protection Division establishes the statewide rules, while county environmental health departments administer permits locally.
Gwinnett County Environmental Health, part of the Gwinnett County Board of Health, manages OSMS permits for properties in the county outside municipal sewer service areas. The county operates under Georgia EPD rules with any locally adopted additions or variations. Gwinnett's high growth rate has made its environmental health office one of the busiest in the state for OSMS permitting.

The Georgia OSMS Two-Permit System
Georgia uses a two-permit process for onsite sewage management systems, similar to North Carolina's approach:
Construction Permit: The first permit in the process, issued after a site evaluation confirms the property can support an OSMS. The Construction Permit specifies the approved system type, design parameters, and the area designated for system installation. It authorizes construction to proceed.
Completion Certificate: After the system is installed per the Construction Permit specifications, Gwinnett County Environmental Health inspects the installation and issues a Completion Certificate confirming the system was built as permitted.
For new construction projects, the OSMS Construction Permit is typically required before a building permit can be issued.
The Site Evaluation Process
Gwinnett County Environmental Health evaluates sites before issuing a Construction Permit. The evaluation covers:
- Soil texture, structure, and drainage characteristics at multiple test locations
- Depth to seasonal high water table or limiting soil conditions
- Available space for primary and reserve system areas
- Setback compliance from wells, buildings, property lines, and surface water
- Topographic factors affecting system function and drainage
Gwinnett County's growth-related high application volume means that site evaluation scheduling and permit review timelines can be extended. Contact Gwinnett County Environmental Health at the start of your project to understand current timelines.
Reserve area: Georgia requires that permit applications include a reserve area for future system repair or replacement. The reserve area must be protected from development during construction. Failure to protect the reserve area is a common issue on high-growth construction projects.
Licensed Installer Requirement
Georgia requires that OSMS installations be performed by a licensed contractor. Gwinnett County enforces this requirement. Your installer must hold a valid Georgia OSMS installation license. The permit application will require the contractor's license information.
Common System Types in Gwinnett County
Gwinnett County's predominantly red clay soils and suburban topography create a particular design environment. Many Gwinnett County properties have clay soils with slower percolation rates that affect system design:
Conventional septic systems with drainfield: The standard approach for sites where soil evaluation supports conventional absorption.
Chamber systems: Widely used in Georgia for their flexibility in varying soil conditions.
Low-pressure pipe systems: For sites where soil conditions benefit from pressure distribution.
Alternative systems: For sites where conventional approaches aren't feasible, Georgia EPD rules permit alternative system types with appropriate design.

Frequently Asked Questions
What permits does Gwinnett County require for residential septic installation?
Gwinnett County Environmental Health requires a Construction Permit for all new onsite sewage management system installations. The process begins with a site evaluation application where the property owner or contractor requests a site evaluation from the county. An Environmental Health Specialist visits the property, evaluates soil conditions and site factors, and determines whether the property is suitable for an OSMS and which system type is appropriate. If suitable, a Construction Permit is issued specifying the approved system type and design. A Georgia-licensed contractor installs the system per the permit specifications, protecting the designated reserve area during construction. After installation, Environmental Health issues a Completion Certificate following a satisfactory final inspection.
How long does Gwinnett County septic permit review take for new installations?
Gwinnett County's very high permit volume from the county's rapid population growth means that review timelines are longer than less-active counties. From application submission to Construction Permit issuance, plan for several weeks to a few months depending on the current application queue and site complexity. Contact Gwinnett County Environmental Health at the start of your project for the current estimated timeline. Complex sites, systems requiring alternative designs, or applications with incomplete documentation take longer to process. For new home construction, coordinate the OSMS permit timeline with your overall construction schedule, since a building permit typically can't be issued until the OSMS Construction Permit is in hand.
