Fats, Oils and Grease

  • Fats, oils and grease (FOG) clog pipes and can cause sewer backups. Sewer backups are a risk to human health and the environment. FOG also creates unnecessary wear on private and public sewer pipes. Help keep FOG out of sewer pipes.

    Prevent FOG 

    Food service businesses use grease removal devices to separate FOG from their wastewater. Keeping FOG out of the sewer system helps avoid dangerous sewage spills and costly cleaning.

    • Grease removal devices work best when serviced regularly.
    • Pump-out and service reports sent to the City meet compliance monitoring and limit business and grease removal device inspections.

    Preferred Pumper Program 

    Most food service businesses hire a pumping company to clean out and maintain their grease removal devices. 

    • Using a service provider from the City’s Preferred Pumper Program is recommended.  
    • Preferred Pumpers meet certain service requirements and send service reports to the City.
