Preferred Pumper Program

The Preferred Pumper Program is a voluntary association of grease interceptor pumping companies that have agreed to provide services in accordance with criteria established by multiple regional municipalities. Following standardized procedures ensures that grease interceptors are cleaned correctly to reduce fats, oils and grease (FOG) in the sewer system. Preferred Pumpers also assume responsibility for record keeping and making sure that required reports are submitted correctly and on time to meet city requirements.

Preferred Pumper Program Criteria

The preferred pumper agrees to:

  • Submit a list of facilities pumped out on a regular basis for baseline data collection.
  • Notify the municipality of the weekly/monthly pump-out schedule and notify them of any schedule changes the day before.
  • Accurately complete the FOG Pump-Out Reports and submit them to the respective municipality and to the FOG-generator in a timely manner.
  • Perform pump-outs that meet grease interceptor inspection standards.

Preferred Pumper Program Benefits

  • The Preferred Pumpers membership list provides up-to-date contact information for member companies in a single source.
  • Preferred Pumpers use standard registration and pump-out report forms in all municipalities.
  • Preferred Pumpers are responsible for completing and submitting pump-out reports and assume consequences for discrepancies.
  • Preferred Pumpers maintain current information about the designated FOG contact person for each participating municipality.
