Grease Trap Cleaning Dallas TX under Dallas Water Utilities' liquid waste rules
Grease rules in this city are enforced by Dallas Water Utilities through its Pretreatment and Laboratory Services Division, which runs the Liquid Waste Program. The legal backbone is Chapter 19, Article X of the Dallas City Code, which covers how grease traps are installed and operated and how grease waste is hauled and disposed of. Any commercial or institutional food service operation is expected to have a trap or interceptor sized under the Dallas Plumbing Code.
The service trigger is written into Section 19-126.2. An interceptor has to be fully emptied and cleaned by a licensed hauler at least every 90 days, and sooner whenever floating grease, oils and settled solids reach 25 percent of the unit. For a busy kitchen, the calendar is a ceiling, not a target. Partial skimming does not count; the city wants the whole volume removed, which is why we treat grease trap pumping as a full evacuation every time.
Haulers working inside the city must hold a TCEQ registration plus a city liquid waste transporter permit, issued per vehicle and renewed yearly. Every load moves on the city's five-part trip ticket, a manifest recording the generator, hauler, volume and disposal site, and transporters file those tickets with the Liquid Waste Program monthly. Keep your copy on site where an inspector can see it.
The city also takes part in the regional Defend Your Drains North Texas campaign: fats, oils and grease belong in a container, not the sink. Inspectors who find an overdue trap or missing tickets can issue a notice of violation, so steady grease trap cleaning is the cheapest way to stay off their list.
