Grease Trap Cleaning Fort Worth TX under the Water Department's pretreatment rules
Grease rules here are enforced by Pretreatment Services, a division of the Fort Worth Water Department working out of the Fournier Street offices. Restaurants and other designated food service establishments must hold a restaurant wastewater discharge permit before sending kitchen wastewater to the sanitary sewer, and anyone installing a new trap has to coordinate with Pretreatment Services and the Plumbing Inspection Section first. The governing rules sit in Chapter 12.5 of the City Code, the environmental protection and compliance chapter.
The city does not lean on a 25 percent measurement the way some neighbors do. Instead, Fort Worth requires every grease trap to be pumped out completely, 100 percent of its contents, at least once every 90 days, and more often when the load demands it. Pretreatment staff can order a shorter interval for any site they believe is putting the collection system at risk. A partial skim of the top layer does not meet the rule, which is why our grease trap pumping always goes down to the floor of the tank.
Only city-permitted liquid waste transporters may remove trap waste, and each one must first be registered with TCEQ. Before anything leaves your property, the hauler presents a five-part Scantron Liquid Waste Trip Ticket, which you complete with your city-issued business ID number. You keep the yellow copy as a receipt until the goldenrod copy comes back from the disposal facility, then file that final ticket on the premises for at least five years.
Section 12.5-731 also bars enzymes, bacteria and other bioremediation products unless the city approves them in advance. Missed pump-outs, unpermitted haulers and sloppy records can each draw penalties of up to $2,000 per violation per day, so we treat the paperwork as seriously as the vacuum hose.
