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 contain harmful bacteria unhealthy for people and pets.
• Sewer water may spill into the gutter and storm drain system and contaminate local waterways.
• Untreated sewage that reaches waterways can cause foul odors, kill wildlife, and cause illness in people and pets.

Report sewage bubbling up from a maintenance hole or pooling in a grassy area to the City immediately by calling the 24-Hour Emergency Service Center.    

Prevent SSOs

At Home

• Never pour grease down sinks, drains, or toilets.
• Collect cooking fats, oils, and grease into a closed container and dispose of them in the garbage.
• Before washing, wipe grease from pans with a paper towel.
• Catch food scraps with baskets or strainers in sink drains; throw scrapes in the Organics (green/food waste) cart.

• Visit the Residents page for more ways to prevent SSOs.

Restaurants and Building Owners

• Recycle grease and oil.
• Dry wipe pots, pans, and dishware before washing.
• Do not pour FOG down sinks, floor drains, or onto parking lots or streets.
• Check and maintain grease traps regularly.
• Never put solids into grease traps or interceptors.
• Provide regular employee training on the proper disposal of FOG.
