Quick answer

Keep everyone out of the area, stop using water and toilets, and do not try to clean sewage yourself. The City of Gainesville maintains sewer lines inside city limits, so call the city if the blockage may be on its side. Standard homeowners policies do not cover sewer backups unless you added a water backup endorsement.

  1. Stop using water in the house. Every flush or load of laundry adds to the backup.
  2. Keep children and pets away from the affected area.
  3. Do not touch it without protection. Sewage carries bacteria and viruses. Wear rubber gloves and boots if you must go near it.
  4. Check whether neighbors have the same problem. If they do, the city's main is the likely cause. Call Water Resources.
  5. Photograph the damage, then call for professional sewage cleanup.

Is the sewage backup in your line or the city's?

The City of Gainesville provides and maintains sewer lines for customers inside city limits. If you are outside city limits, your sewer may be run by Hall County Sewer Services or a town like Flowery Branch, even if the bill comes from Gainesville (City of Gainesville).

  • The building sewer from your house to the city's cleanout, usually at the curb or right-of-way, is generally the owner's to maintain and repair (summary of Gainesville Code Sec. 5-1-95).
  • Main backups or breaks go to the water and sewer repairs shop at 770-535-6881 on weekdays, or the emergency line at 770-535-6877 after hours (City of Gainesville).
  • Basement fixtures below street level: Georgia plumbing code requires a backwater valve if a fixture in your home sits below the next upstream manhole (Gwinnett County). If you do not know whether you have one, ask a plumber.

Can storms cause sewage backups in Gainesville?

The July 24, 2026 storm caused about 1,200 gallons to overflow from a manhole near Autumn Lake Drive, on top of the larger spill at the Flat Creek plant (AccessWDUN). Georgia's spill report lists both under heavy stormwater (Georgia EPD). When sewer lines fill with stormwater, homes on the line can back up even when their own plumbing is fine.

What does proper sewage backup cleanup look like?

  • Workers in protective gear remove the sewage and contaminated water
  • Porous items that were soaked, like carpet, pad, and the lower part of drywall, are usually removed and thrown out
  • Hard surfaces are cleaned and disinfected
  • The area is dried with dehumidifiers and air movers, with moisture readings until dry

Sewage is Category 3 water, the most contaminated kind. See clean, gray, and black water.

Is sewage backup covered by homeowners insurance?

Standard homeowners policies do not cover sewer or drain backups. That coverage comes from a water backup endorsement, usually added for a modest cost (Insurance Information Institute). Check your declarations page. See what homeowners insurance covers.

Common questions

Is it safe to stay in the house?

Usually yes if the backup is contained to one area and you avoid it. Anyone with a weakened immune system, young children, and pregnant women should stay away from the affected area until it is cleaned.

Can I clean up a small toilet overflow myself?

A small overflow from the bowl can often be cleaned with gloves and disinfectant. A backup from a floor drain or one that soaked carpet or drywall needs professional cleanup.

How much does sewage cleanup cost?

Water damage jobs average about $3 to $7.50 per square foot, and sewage sits at the top of that range because it is the most contaminated water (Angi). The total depends on how much carpet, pad, and drywall has to be removed, so a basement sewage cleanup costs more than a single bathroom. Ask for a written estimate before work starts, and check whether you have water backup coverage.

How do I know if the problem is the city's main?

If neighbors are backing up too, or the city's cleanout at the curb is full, the main is the likely cause. Call Water Resources.
