Sewage Backup: What to Do First in New York
A sewage backup is one of the most serious water problems a home can have. Sewage is Category 3 black water and a health hazard, and the first steps are entirely about keeping people away from it.

There is no DIY sewage cleanup advice in this guide, because there should not be. The right response is to avoid contact, stop adding water to the system, and call a professional.
Avoid contact with sewage
Do not touch sewage or water that may contain it, do not step in it, and do not let children or pets near it. If sewage has backed up into a basement, a bathroom or a shower, stay out of the affected rooms entirely.
If the backup is still rising, leave the area and call for help from outside the room. Do not try to bail it out, mop it up, or clear a drain yourself while sewage is present.
Do not enter contaminated water
Contaminated water can hide hazards you cannot see, including sharp objects and electrical risks. Wading through it to reach a valve, a drain or a belonging is not worth the risk, and it can spread contamination to other parts of the house.
If you need to reach a shut-off, do so only from a dry place. If the only route is through contaminated water, leave it and let a professional handle it.
Shut off water use in general terms
Stop using water in the house: do not flush toilets, run taps, use the washing machine or run the dishwasher. Every litre that goes down a drain can add to a backup while the sewer is blocked, so keeping water use to zero matters.
If you can safely reach the main water shut-off from a dry place, turn it off. Our page on sewage cleanup explains what professional cleanup covers once the backup is stopped.
Call a professional
Call a professional and describe where the sewage appeared, how far it spread, and whether it is still rising. Take photos from a safe distance if you can, and note when you first noticed it.
In the west of the state, sewage backup help in Buffalo follows the same professional-only response, and emergency water removal covers the removal stage once the contaminated water is dealt with. Do not re-enter the affected rooms until a professional has advised it is appropriate.
