Recognizing Septic System Warning Signs
Homeowners can identify potential issues with their on-site sewage management system by monitoring specific symptoms. However, diagnosing the root cause requires professional evaluation, as many signs overlap with other plumbing or environmental factors.
Common Warning Signs
Warning signs requiring prompt professional review include slow drains, plumbing backup, gurgling sounds, sewage odors indoors or outdoors, wet or mushy soil, gray standing water, and unusually green or fast-growing grass over one area.
Bacteria detected in well water is also a critical indicator. Georgia prohibits sewage seepage to the ground surface, ditches, storm drains, wells, groundwater, or surface waters.
Maintenance and Prevention
Regular inspection and pumping are essential. UGA recommends inspection every 3–7 years and pumping typically every 3–5 years, depending on household size and usage.
Homeowners should conserve water, spread laundry across the week, repair leaks, limit garbage disposal use, and flush only human waste and toilet paper.

Post-Flood Protocols
After flooding, do not use the system until soil-absorption-field water has receded. Pumping while the drainfield is saturated can cause an emptied tank to float or 'pop out'.
Keep children and pets away from surfaced sewage. Reduce wastewater use and seek professional and Environmental Health guidance immediately.

System Components and Terminology
The system includes the tank, drain/discharge lines, and soil treatment area. A distribution box may divide flow among lines.
Alternative systems may include pumps, controls, or other components and generally require more frequent inspection, commonly annually.

Digging and Utility-Locate Safety
Do not probe or excavate around a septic system before utility locating. Contact Georgia 811 for participating utility lines and confirm responses before digging.
Owner-installed or other private lines may not be marked through 811 and can require a separate private locator. Leave tank opening, probing, and excavation to qualified professionals.

Frequently asked questions
What are the signs of a failing septic system?
Slow drains, backups, gurgling, sewage odors, wet soil, standing water, unusually green grass, or bacteria in well water are warning signs that require professional evaluation. They do not identify the failed component or required repair by themselves.
Can I pump my septic tank after a flood?
No. Do not pump while the drainfield or soil is flooded or saturated, as an emptied tank can float. Wait until water recedes and consult a professional.
How often should I inspect my septic system?
UGA Extension recommends inspection every 3–7 years, and pumping typically every 3–5 years, depending on usage and system type.
Are septic additives necessary?
No. UGA says no additives are needed, and DPH discourages their use. Additives do not eliminate the need for pumping.
What should I avoid doing over my septic field?
Do not drive or park over the tank/drainfield, avoid structures or impervious paving over the field, and direct stormwater away from the system.
