What should I do in a septic or sewer emergency in Grayson, GA?
Stop using water first. Then work out which system you have: Grayson mixes Gwinnett sewer with many septic homes. Sewage from a manhole or the street goes to Gwinnett DWR at 678.376.7000. A backup inside, or a flooded tank or drain field, is private. Call us now; we'll tell you how fast we can be there.↗↗

Sewer or septic?
Step one: which system are you on?
The fastest check during an emergency is your last Gwinnett water bill. The county's septic page says a Sewer Amount Charged of $0.00 means you are almost certainly on a tank. Grayson's comprehensive plan explains why so many are: sewer simply was not available here until recent years.↗↗
How to tell which one you have
- Bill shows a sewer charge: you are on county sewer.
- Bill shows $0.00 for sewer: you almost certainly have a tank.
- A green lid or riser in the side or back yard marks a tank.
The Grayson story
If you are on sewer: right now
Shut off appliances that drain, stop flushing, and look at the street and the grass strip by the curb. Gwinnett routes sewer backups and spills, overflowing manholes and sinkholes to its dispatch line. A clog in the main or in the short piece of lateral inside the right-of-way is the county's to clear; the rest of the line back to the house is yours.↗↗
Split-level houses and basements take the worst of it. If the lowest fixture sits below the next manhole upstream, the plumbing code requires a backwater valve, and the county does not accept liability for backup damage without one. We check for it on every basement call in Grayson.↗

More about Grayson
If you are on septic: right now
Cut water use to the minimum, keep children and pets off wet ground over the drain field, and do not open or lean over the tank. Then gather what helps us move quickly: where the lid is, when it was last pumped, and whether the trouble followed heavy rain. If you do not know where the tank sits, Gwinnett Environmental Health keeps septic records going back to 1959.↗
A pump-out gives relief, but a tank that fills again within days points to a drain field problem, and a failed field repair needs a GNR permit before work begins. We tell you which one you are facing once the tank is open.
