Grease Interceptor Maintenance Program

Disposing of grease, oils and fats improperly turns municipal sewer systems into a greasy underworld. Not only are these smelly messes hazardous to public health, they can make a mess of streets, or even back up into your restaurant and shut you down. City Ordinance Number 2012-176 proactively prevents problems before they happen, by requiring restaurants to keep their grease interceptors in good working condition.

Here's what you must do to comply with the ordinance:

  • Have your grease interceptor pumped at least once every 90 days
  • Use a company permitted by the city
  • Sign the manifest (or trip ticket) provided by the maintenance company for each pump-out, and keep it on-site for at least three years
  • Do not use additives in your grease interceptor unless you receive written authorization from the city
  • Maintain your grease interceptor in effective operating condition


A city industrial pretreatment inspector will visit your restaurant to verify that your grease interceptor is serviced at least once every 90 days by a permitted Liquid Waste hauler. The inspector can issue a notice of violations and citations for:

  • Failure to service your grease interceptor at least every 90 days
  • Not having manifests on-site
  • Using a non-permitted transporter

25 Percent Rule

Ordinance Number 2012-176 requires that all grease interceptors must be pumped at least once every 90 days, or when the grease and solids reach 25% of the wetted height of the interceptor. Using a long pole, an inspector will measure the layers in your interceptor.
