Grease trap pumping removes accumulated fats, oils, and grease (FOG) before it exceeds the trap's capacity and causes backups or a permit violation. Metro Water Services requires Nashville restaurants and commercial kitchens to keep grease interceptors maintained on a regular schedule -- most kitchens need pumping anywhere from monthly to quarterly depending on volume and trap size. Metro's minimum service intervals differ by unit type: smaller under-sink grease traps must be serviced at least every 30 days, while larger in-ground grease interceptors must be serviced at least every 90 days, regardless of how full they appear.

  • Scheduled or on-demand pumping
  • Proper FOG disposal and manifest documentation
  • Sized for both small under-sink traps and large in-ground interceptors
  • Meets Metro's minimum service intervals (30 days for traps, 90 days for interceptors) even between full-based cleanings
