Grease Trap Pumping Near Houston, Texas: What Restaurants and Commercial Properties Need to Know

Running a restaurant or commercial kitchen in the Greater Houston area comes with a unique set of challenges, and managing fats, oils, and grease (FOG) is at the top of the list. The City of Houston enforces strict regulations to protect its sewer system from blockages that cause sanitary sewer overflows. For food service operators, understanding and complying with these local rules is not just about avoiding fines; it is about keeping your kitchen running smoothly and protecting the local environment.

Whether you operate a bustling restaurant in downtown Houston or a commercial kitchen in a neighboring county, proper grease trap maintenance is a legal requirement. This guide covers the essential facts about grease trap pumping, local regulations, and what commercial properties need to know to stay compliant.

Understanding Houston's FOG Regulations

The Houston Public Works Department manages a Special Waste Program that requires every restaurant or food facility generating special waste to obtain a permit. Special waste includes fats, oils, and grease, which can solidify in pipes and cause severe blockages. According to Houston Public Works, 70 percent of sewer overflows in Houston are caused by clogs from fats, oils, and grease poured down drains.

To combat this, the City of Houston Code of Ordinances (Section 47-512) mandates that commercial kitchens install a properly sized grease trap or interceptor. Furthermore, these businesses must use a transporter permitted by the city to handle and dispose of the waste. Violating these regulations can result in Notices of Violation, citations with fines ranging from $250 to $2,000 per offense, or even the suspension of water and sewer services.

The 90-Day and 25 Percent Rules

One of the most critical aspects of grease trap compliance in Houston is the cleaning frequency. The city requires that every interceptor be fully pumped and cleaned at least once every 90 days. This applies unless the facility has applied for and received a written Notice of Waiver from the Houston Public Works department allowing for a different schedule.

In addition to the 90-day rule, many Texas municipalities and industry best practices follow the "25 percent rule." This rule states that a grease trap must be pumped when the total volume of floating grease and settled solids reaches 25 percent of the trap's total liquid depth. Even if 90 days have not passed, reaching this 25 percent threshold means the trap is no longer functioning efficiently and must be serviced immediately to prevent grease from escaping into the city sewer lines.

Manifests and Record Keeping

Compliance does not end when the pump truck drives away. Record keeping is a major component of Houston's Special Waste Program. Every time a grease trap is pumped, a waste manifest must be generated. This document tracks the waste from your facility to its final disposal site.

As a restaurant owner or manager, you must inspect the trap to ensure it is completely empty before signing the generator portion of the manifest. The city requires businesses to keep both the generator copy and the returned copy of these manifests on-site for a period of five years. During routine or complaint-driven inspections, health department investigators will ask to see your original FOG permit, copies of these manifests, and records of previous inspections. Failing to produce these documents can lead to immediate citations.

Protecting Your Business and Plumbing

Regular grease trap pumping does more than satisfy city inspectors; it protects your business infrastructure. When a grease trap is neglected, the FOG hardens and builds up, leading to slow-draining sinks, foul odors in the kitchen or dining area, and eventually, raw sewage backing up into your facility. A plumbing backup can force a restaurant to close its doors during peak hours, resulting in lost revenue and a damaged reputation.

Implementing best management practices in the kitchen can help extend the life of your grease trap between pumpings. Staff should be trained to dry wipe pots and pans before washing them, use sink strainers to catch food particles, and never pour cooking oil down the drain. Partnering with a licensed and experienced septic and excavation professional ensures that your grease trap is not only pumped correctly but also inspected for damaged baffles or failing seals that could cause future emergencies.
