Managing a grease trap can feel tricky, but understanding this key rule could save you time, money, and headaches.

Whether you’re a restaurant owner, a facility manager, or someone responsible for grease trap cleaning, this guide will equip you with practical insights and actionable tips. By the end, you’ll know exactly how to stay compliant, avoid common pitfalls, and maintain an efficient drainage system that protects your business and the environment.
Understanding the Origins and Basics of the 25% Rule
Before we get into the nitty-gritty, it helps to know how the 25% rule came about and why it’s such a big deal in grease trap maintenance. The rule is a standard adopted by many municipal water and health authorities—including Sacramento—to regulate the amount of fats oils and grease (FOG) that accumulate in your trap.
Put simply, the 25% rule means that once the accumulated grease reaches one-quarter of the grease trap’s total capacity, it’s time for regular cleaning. This standard helps prevent grease blockages, foul odors, and costly damage to your plumbing system.
Over the years, this rule evolved from practical experience and environmental necessity. Grease traps not only protect your kitchen’s plumbing but also prevent grease from entering the city’s sanitary sewer system, where it can cause backups and sanitary sewer overflows. Sacramento’s regulations emphasize this rule because it balances operational efficiency and environmental responsibility.
Today, the 25% rule is enforced by local health inspectors and wastewater authorities, making it essential knowledge for anyone managing a grease interceptor. Staying ahead of this requirement helps you avoid penalties and keeps your kitchen running smoothly.
Breaking Down the 25% Rule: What You Need to Know
Let’s unpack the 25% rule in everyday terms so you can confidently apply it to your grease trap cleaning routine. Think of your grease trap as a bucket designed to catch fats oils and grease (FOG) before they enter the sewer system. The 25% rule is the indicator telling you when that bucket is getting too full.
Key Components:
- Capacity Monitoring — The total capacity refers to the entire volume inside your grease trap or interceptor tank.
- Grease Accumulation Threshold — When grease, food solids, and other solids reach 25% of that volume, it triggers the cleaning requirement.
- Cleaning Frequency — Depending on your kitchen’s size and usage, this might mean weekly, biweekly, or monthly grease trap cleaning.
- Inspection and Measurement — Regularly checking grease levels using inspection ports or professional services ensures compliance.
- Record Keeping — Documenting cleanings and inspections is crucial for health inspections and audits.
Understanding these components helps you make grease trap maintenance predictable rather than reactive. For example, a busy commercial kitchen producing high volumes of FOG may need more frequent cleanings, while a smaller café might have more flexibility.
Practical Examples of the 25% Rule
- A medium-sized restaurant in Sacramento measures grease at 20% capacity during weekly checks — no cleaning needed yet, but keep monitoring closely.
- A large catering kitchen hits 30% capacity within two weeks — time to schedule immediate cleaning to stay compliant and prevent blockages.
Mastering these practical details means fewer surprises and a smoother relationship with local regulators.
Why the 25% Rule Matters: Benefits of Compliance and Efficiency
Following the 25% rule isn’t just about avoiding fines—it also brings real benefits to your operations and the environment. When you keep your grease trap within this limit, you:
- Prevent Plumbing Issues — Avoid costly clogs and back up that disrupt business.
- Reduce Health Risks — Minimize foul odors and unsanitary conditions in your kitchen.
- Stay Regulatory-Compliant — Meet Sacramento’s legal standards and pass inspections with ease.
- Protect the Environment — Stop fats oils and grease from polluting waterways and the sanitary sewer.
- Save Money Long-Term — Regular grease trap pumping and maintenance costs less than emergency repairs or fines.
Beyond these, compliance builds your reputation as a responsible business owner committed to quality and sustainability.
