If you’ve worked in or managed a restaurant, cafeteria, or any commercial kitchen, you’ve likely seen—or smelled—a grease trap in action. These unassuming units sit calmly beneath sinks or floors, silently protecting your plumbing system. But when neglected, grease traps can quickly turn from protective fixtures into liabilities, causing clogs, foul odors, regulatory trouble, and costly repairs.
In this post, we’ll explain:
- What grease traps are and how they work
- The risks when they’re not cleaned
- Texas regulations you need to know
- How often cleaning should be done
- Why you should call a professional Houston plumber
Let’s dive in and discover why grease traps should never be out of sight or ignored.
What Is a Grease Trap?
A grease trap (or interceptor) is a plumbing device designed to capture fats, oils, and grease (FOG) before they enter the sewer system. As wastewater flows through the trap, grease floats to the top while heavier debris sinks, allowing only relatively clean water to pass downstream.
These traps are required in commercial kitchens, food trucks, and many institutions that use truckloads of cooking oil. Left unchecked, that settled grease solidifies, undermining the trap’s function and clogging pipes.
What Happens If You Don’t Clean Your Grease Trap?
1. Nasty Backups and Odors
As grease thickens and blocks the trap, wastewater starts pooling and overflowing. That means foul water could back up into sinks, floor drains, or restrooms—creating unsanitary conditions and health hazards.
2. Fines and Health Code Violations
Any establishment generating cooking grease must use a grease trap under municipal plumbing codes. Neglecting regular maintenance can result in citations, suspended operations, or even forced temporary shutdowns.
The TCEQ’s RG‑389 guidance explains that only registered transporters may pump these traps. The TCEQ grease trap regulations require proper management from grease generation to final disposal.
3. Clogged Sewer Systems
When a saturated grease trap overflows, FOG flows into public sewers. There, it contributes to large blockages—or fatbergs—that threaten city sewer infrastructure, causing backups and requiring expensive municipal repairs.
4. Costly Repairs and Lost Business
Ignoring a grease trap might save cash upfront, but downstream problems—plumbing line clogging, health inspections, or sewer line replacement—can end up costing far more than regular service. These emergencies also disrupt operations and damage your reputation.
How Often Should Grease Traps Be Cleaned?
Cleaning frequency depends on kitchen volume, menu, and local ordinances, but here are common guidelines:
Small establishments (like coffee shops): every 3 months or when FOG exceeds 25% of total capacity.
Busy restaurants: often monthly due to heavy oil use.
High-output venues: may require quarterly or even bi-weekly cleanings.
Common warning signs that cleaning is overdue:
- Slow drains or backups
- Foul odors near sinks
- Visible grease floating on the trap’s exit line
- Reports from city inspectors
Many cities require owners to keep records of pump-outs, waste disposal, and trap inspections. Partnering with a professional service like TX Hydrojet ensures compliance and clean operation.
Who Regulates Grease Trap Cleaning in Texas?
Several bodies play a role:
- TCEQ handles the transportation and disposal of grease trap waste.
- Local health departments enforce trap installation and maintenance in food service facilities.
- Texas Department of State Health Services (DSHS) may also oversee grease trap design during permitting.
- Businesses must use registered haulers—self-emptying is prohibited under TCEQ rules.

Frequently Asked Questions
What does a grease trap do?
A grease trap is a plumbing device that captures fats, oils, and grease (often referred to as FOG) from kitchen wastewater before it enters the main sewer system. It works by slowing down the flow of water, allowing lighter grease to float to the top while heavier solids settle at the bottom. The cleaner water then flows out through an outlet pipe.
How often should I clean it?
Most grease traps need to be cleaned every 1 to 3 months, depending on how much grease your kitchen produces. Smaller operations may go longer between cleanings, but busy commercial kitchens often need monthly service. Industry standards recommend cleaning once the trap reaches 25% of its capacity in grease and solids.
What happens if I don’t clean it?
Neglecting grease trap cleaning can cause serious issues. Clogs and backups are common, and they often result in foul odors, sink overflows, and even raw sewage entering your facility. Unmaintained traps can also lead to plumbing damage, health code violations, and in some cases, temporary business closures.
Can I clean a grease trap myself?
Not in Texas. State law requires that grease trap waste be pumped and hauled only by transporters registered with the Texas Commission on Environmental Quality (TCEQ). Attempting to clean and dispose of trap waste on your own could lead to fines or improper disposal, which can harm the environment and violate health codes.
Who regulates grease trap disposal in Texas?
The TCEQ oversees the pumping, transportation, and final disposal of grease trap waste across the state. Local wastewater authorities or health departments may also regulate how traps are installed, maintained, and inspected.
How do I tell when a grease trap is full?
There are a few common signs: slow-draining sinks, unpleasant odors near drains, or visible grease floating near the trap’s outlet. Some systems also have monitoring tools. A licensed technician can perform a visual inspection to confirm if cleaning is needed.
Are grease traps required?
Yes. Any commercial or institutional kitchen that produces cooking grease or oily wastewater is typically required to install a grease trap or interceptor. This includes restaurants, school cafeterias, hotels, and food preparation businesses located in areas that have adopted plumbing codes.
