  • Sewer Backup to report water or sewage coming out a toilet, sink drain, or bathtub drain as a result of heavy rainfall or flooding

New York City provides information about how to clean a home after a flood or sewage overflow.

It is important to thoroughly clean and disinfect inside your home after a flood or sewage overflow. Flood water may contain sewage water and germs. Direct exposure may infect your eyes, skin, stomach or intestines.

These basic clean-up guidelines and health precautions are recommended:

  • Do not eat or drink anything exposed to flood or sewer water.
  • Wear rubber boots, gloves and protective goggles during cleanup.
  • Discard any clothing or household items that can't be thoroughly cleaned, disinfected and dried.
  • Keep children, pets and people with compromised immune systems out of contaminated areas until cleanup is complete.
  • Seek professional cleaning help for homes with extensive flood damage.
