Fats, Oils & Grease (FOG)

When Fats, Oils, and Grease (FOG) go down the drain, they build up in pipes to cause clogs. These clogs can cause a sewer pipe to break or back up into the street, causing a Sanitary Sewer Overflow (SSO). SSOs are trouble for everyone.

  • They contain harmful bacteria unhealthy for people and pets.
  • They sometimes spill into the gutter and storm drain system before we can get there.
  • Raw sewage in waterways can cause foul odors, kill wildlife, and make waterways unsafe.

See how FOG affects our sewers with our "Fats, Oils, Grease" video in the City's Video Archive.

Help Us Keep It Off the Streets

If you see water and sewage bubbling up from a maintenance hole or pooling in a grassy area, please report it immediately by calling the Emergency Service Center
