Inside the Commercial Grease Trap: A Complete Overview

Understanding What Lies Beneath the Kitchen Floor

Though often overlooked, this essential device keeps kitchens running smoothly while preventing environmental damage.

In Sacramento, CA, where the restaurant scene thrives, proper grease management isn’t just a best practice—it’s a legal requirement. A neglected commercial kitchen grease trap can cause plumbing issues, foul odors, and even health code violations.

By the end of this guide, you’ll understand:

• What a commercial grease trap is and how it works
• How often it needs cleaning and maintenance
• Sacramento-specific compliance and inspection rules

Let’s take a look inside this vital kitchen system and see how it protects your business, your pipes, and the planet.

What Is a Commercial Grease Trap and Why It Matters

A commercial grease trap (also known as a grease interceptor) is a plumbing device designed to capture fats, oils, and grease (FOG) before they enter the public sewer system. When mixed with wastewater, these materials can harden and cause severe blockages in both restaurant plumbing and municipal lines.

In Sacramento, the Environmental Utilities Department requires all food establishments to install properly sized grease interceptors to prevent sewer contamination.

Key benefits of a well-maintained grease trap include:

• Prevents costly pipe blockages and backups
• Protects the environment by keeping grease out of waterways (EPA)
• Ensures compliance with Sacramento wastewater regulations
• Reduces unpleasant kitchen odors
• Improves long-term plumbing efficiency

However, without regular care, even the best-installed grease traps for commercial kitchens can fail, resulting in emergency costs and possible restaurant shutdowns.

How a Commercial Grease Trap Works Step-by-Step

Understanding how a commercial grease trap functions will help you appreciate the value of consistent maintenance and cleaning.

Step 1: Wastewater Enters the Grease Trap System

When dishwater and wastewater flow down sinks or floor drains, they carry solids, grease, and hot water. This mix enters the inlet chamber, where the flow slows, allowing separation to begin.

Purpose: Slow flow encourages natural separation of fats and solids.
Pro Tip: Installing sink strainers before the inlet minimizes buildup and reduces commercial grease trap cleaning frequency.

Step 2: Separation of Fats, Oils, and Grease from Water

Inside the main chamber, lighter grease and oil rise while solids sink. The cleaner, grease-free water remains in the middle layer.

Purpose: Allows clean water to exit while trapping harmful FOG.
Pro Tip: Temperature matters—hot water cools inside the trap, aiding grease solidification.

Step 3: Clean Water Exits, Waste Stays Behind

The middle layer of treated water exits through an outlet pipe into the main sewer system. Floating grease and settled solids remain in the trap.

Purpose: Ensures only treated water enters Sacramento’s public sewer.
Pro Tip: Schedule commercial grease trap cleaning near me every 1–3 months to avoid overflow or compliance issues.

Step 4: Routine Cleaning and Pumping Services

When the trap reaches 25% capacity, it must be cleaned. Professional commercial grease trap cleaning services use vacuum trucks to remove solids, FOG, and water, thoroughly cleaning the trap walls.

Purpose: Maintains flow efficiency and prevents odors.
Pro Tip: Keep a grease trap maintenance log—Sacramento inspectors often request service records during checks.
