Backed-up drains and dirty water near Lilburn
Sewage Backup Cleanup in Lilburn, GA
Did a toilet, tub or floor drain push dark, smelly water into the house? For sewage damage, the EPA's advice is a professional experienced with contaminated water. Stay out of the room, keep others out too, and call (678) 835-3780.

Step back and get help if
Sewage on the floor: nobody wades in to look, and kids and animals stay in another part of the house.
Drains that keep pushing water up: quit using every sink, tub and toilet, then phone the sewer utility. That is 678.376.7000 in Gwinnett County or 770-270-6243 in DeKalb County.
Cords, outlets or appliances sitting in the water: keep your feet out of it, and 911 is the call if anything sparks or smells burnt.
Food, dishes or toys that touched the water: keep them away from children. The CDC's throw-away list includes food exposed to flood or storm water.
Local numbers and facts
Gwinnett's sewer lateral page makes the owner responsible for the private lateral up to the right-of-way line. Of the cleanouts on the lateral, the county looks after the one at that line, and the owner looks after any set nearer the house.
A basement toilet or sink that sits below the next upstream manhole brings in Georgia plumbing code, which requires a sanitary backwater valve between the house and the public sewer. The owner maintains it, and the county says it would not be responsible for damage if a required valve is missing.
Lilburn's stormwater page sends sewer overflows to Gwinnett County Dispatch, 678-376-7000. DeKalb's emergency page lists 404-294-2007 for sewage overflows and 770-270-6243 for sewage system emergencies.
Why two sewage jobs rarely match
No price appears on this site. The work is sized by how far the water spread, what it soaked, how long it sat and how much has to be removed and bagged. Protective gear and disposal go with it. Where the stoppage started, on the house side of the lateral or out in the county's pipe, decides who clears it. That is separate from the cleanup.
What people ask before they call
How serious is a sewage backup, from 1 to 10?
Eight to ten: sewage is still spreading, a drain keeps pushing water up, or wiring sits in the water. Get clear, dial 911 for shock, and phone the sewer utility. Four to seven: the backup has stopped but a room is soiled, so call (678) 835-3780. One to three: a slow drain with no overflow, which is a plumbing question.
Can I clean up sewage myself?
For a house soaked by sewage or other contaminated water, the EPA recommends calling a professional with experience in that cleanup. The CDC also warns that sewage and mold can be present in a flooded house. Until someone arrives, keep children and pets out.
Whose pipe is the blockage in?
Gwinnett's lateral page puts the private lateral under the owner's care all the way to the county's right-of-way line, with the county looking after the cleanout at that line. The utility can help work out which side of the line a blockage is on.
What is a backwater valve?
It is a valve between the house and the public sewer that closes when sewage backs up at the upstream manhole. Gwinnett says Georgia plumbing code requires one when the lowest fixture is below that manhole, and that an older house may be worth checking.
What happens to carpet that touched sewage?
Georgia's insurance office says soaked carpeting and padding get pulled up and discarded after a flood, since floodwater picks up sewage and chemicals along the way. The EPA adds that porous materials like carpet may have to be thrown away. Photograph everything before it goes.
Is sewage cleanup offered in Tucker and Snellville too?
Yes, Lilburn, Tucker and Snellville are all covered. The pages for water damage in Tucker and water damage in Snellville list the utility numbers for each town. Say which drain backed up, then call (678) 835-3780.
Before anyone goes in
- 1
Keep children, pets and visitors out.
- 2
Stop using drains and toilets.
- 3
Stay out of any room where cords or outlets touch the water.
- 4
Photograph from the doorway, not from inside the water.
- 5
Call (678) 835-3780 with the room, the flooring and when the backup began, and call the sewer utility about the source.
No month owns this problem
Gwinnett's backwater-valve page describes the public sewer taking a surge in flow, and no county page ties backups to a calendar month. For the rain side of it, the Atlanta airport normals show an inch or more falling on 1.0 to 1.6 days in every month. The station is the airport, not Lilburn. Tell the contractor the date the backup began.
Sewer work and who may do it
Digging up a lateral or adding a backwater valve is plumbing work with rules of its own. The offices to ask in Lilburn, Tucker and Snellville are on choosing a contractor.
Keep the address, the wet room and the flooring type handy, then call (678) 835-3780. For a rental, contact the landlord or property manager first.
