Understand how grease trap pumping differs from septic pumping for licensing and compliance documentation

Steps

1. Recognize grease traps/interceptors serve food-service facilities to capture fats, oils, and grease (FOG) before wastewater reaches the sewer, while septic tanks treat/dispose of household or facility wastewater on site - these are different waste streams with different disposal pathways
2. Confirm local licensing separately - a septic pumper license does not automatically authorize grease trap/interceptor hauling in every jurisdiction, and some localities regulate FOG haulers under their sewer-use/pretreatment program rather than the septage program
3. Check the destination facility requirements: septage typically goes to a permitted treatment facility or approved land-application site under septage rules, while grease trap waste is commonly directed to a facility equipped to handle FOG (e.g., rendering, anaerobic digestion, or a wastewater treatment plant accepting FOG loads)
4. Maintain separate service/compliance documentation for each waste stream, since grease trap service events are typically tracked under a local sewer-use/pretreatment recordkeeping requirement rather than a state septage manifest
5. Confirm service frequency expectations differ substantially - grease traps at active food service establishments are commonly serviced monthly or more often, while septic tanks are commonly serviced on a multi-year cycle
