How backups happen in Flushing
Combined sewers serve most of the Flushing Bay area, so rain and household waste share the same pipes. DEP built a 43 million gallon underground retention facility on Flushing Bay to reduce overflows, yet heavy rain can still overwhelm the system. After the July 18, 2026 flooding, residents said clogged drains made street water rise and back up through toilets and bathtubs into basements.
- Water rising through the lowest floor drain in the basement.
- Toilets and tubs overflowing as street water backs up.
- A blocked service pipe between the building and the street sewer.
From removal to a clean, dry room
The crew seals the work area, wears protective gear and removes the carpet, pad, lower drywall and insulation the water reached, because porous materials cannot be made safe. Hard surfaces are cleaned and treated with an EPA-registered antimicrobial before any drying begins.
- HEPA air scrubbing while materials come out.
- Bagged waste carried out without crossing clean rooms.
- Drying and daily readings once cleaning is complete.
Who owns the pipe, and the next backup
DEP says the property owner owns and must maintain the service pipe from the building to the sewer main in the street. It also says a backflow device can help, though the law does not require one for most NYC homes. The basement backup risk check is a quick way to size up a building, and toilet overflow cleanup covers single-fixture spills.

Sewer Backup Cleanup questions in Flushing, NY
Why is sewage handled differently?
Sewage is Category 3 the moment it appears. Porous materials it touched are removed, the area is contained and surfaces are treated with an EPA-registered antimicrobial before any drying.
Why did water come up through my tub?
Combined sewers carry rain and waste together. When street water rises faster than the system can take it, the mix backs up through the lowest openings, which can be a basement floor drain, a toilet or a tub.
Who is responsible for the sewer pipe?
DEP says the owner owns and must maintain the service pipe from the building to the street sewer. In a co-op that is usually the building, so the super and the board should hear about a backup right away.
Can the City help?
DEP inspects a reported backup within six hours of the 311 complaint. A claim against the City goes to the NYC Comptroller within 90 days, so keep the complaint number, photos and drying records.
Is a sewer backup covered by insurance?
Often only with a sewer backup endorsement. What is covered depends on your own policy, so ask your insurer before the job starts.
Will a backflow device stop it?
DEP says backflow devices can help, although the law does not require them for most NYC homes. Keeping valuables off the basement floor helps as well.
