What Is a Grease Trap?
A grease trap—also known as a grease interceptor—is a plumbing device designed to capture fats, oils, and grease (FOG) from kitchen wastewater before it enters the sewer system. When water flows from sinks and dishwashers into the plumbing, FOG rises to the top of the trap, while solids settle at the bottom. Only the clearer water in the middle passes through to the sewer.
Over time, these traps fill up and need to be cleaned out. If neglected, they can overflow or clog, causing sewer backups, foul odors, and serious hygiene issues.
Why Grease Trap Cleaning Is Critical in Miami
- Health and Sanitation Compliance
Miami-Dade County has strict health codes requiring food establishments to prevent FOG from entering the municipal sewer system. An overflowing or neglected grease trap can result in unsanitary conditions, health code violations, and even temporary closure.
- Avoid Plumbing Emergencies
Clogged grease traps can cause wastewater to back up into sinks, dishwashers, and kitchen floors. This not only disrupts your business operations but can also lead to costly plumbing repairs.
- Prevent Foul Odors
As grease and food particles accumulate, they decompose and create an unpleasant stench that can waft through your kitchen or dining area—creating a poor customer experience and unsafe working conditions.
- Environmental Responsibility
Improperly maintained grease traps can contribute to sewer overflows, which pollute local waterways like Biscayne Bay. Regular maintenance helps your business operate responsibly within the community.
- Legal and Financial Risk
Failing to comply with Miami-Dade grease management regulations can result in hefty fines, permit revocation, or lawsuits. Regular cleanings ensure you stay on the right side of the law.
How Often Should Grease Traps Be Cleaned?
The frequency of grease trap cleaning depends on several factors:
- The size of the trap
- The volume of food prepared
- Local health regulations
- Type of cooking (fryer-heavy menus produce more grease)
A general rule of thumb is to clean the trap every 1 to 3 months, or when the trap reaches 25% of its capacity in FOG and solids. Miami-Dade County recommends cleaning at least quarterly for most commercial kitchens.
What Happens During a Grease Trap Cleaning?
A professional grease trap cleaning service in Miami will typically follow these steps:

Choosing a Grease Trap Cleaning Company in Miami
Here’s what to look for in a trusted service provider:
- Licensed and Insured: Ensure they are certified to operate in Miami-Dade County.
- Experience with Local Regulations: Familiarity with city and county FOG ordinances ensures proper disposal and recordkeeping.
- Emergency Services: Some companies offer 24/7 response for grease trap overflows or backups.
- Proper Waste Disposal: The service should legally dispose of FOG at licensed facilities—not just dump it down a drain.
- Regular Maintenance Plans: Look for companies that offer scheduled cleanings, so you never fall behind on compliance.
Miami-Dade Grease Ordinance: What You Need to Know
The Miami-Dade Water and Sewer Department (WASD) enforces the FOG Control Program, which mandates that all food service establishments install and maintain grease traps or interceptors. Key requirements include:
- Regular cleaning logs (must be kept for at least three years)
- Proper disposal of FOG
- No chemical additives or enzymes that break down grease into the sewer
- Scheduled inspections by city or county officials
Businesses are subject to both announced and unannounced inspections, and failure to maintain your system can lead to enforcement actions.
Signs Your Grease Trap Needs Cleaning
Watch for these red flags:
- Slow draining sinks or dishwashers
- Gurgling noises in the pipes
- Strong, persistent odors near drains
- Visible grease overflowing from the trap
- Backups in floor drains
If you notice any of these issues, schedule an inspection immediately.
Grease Trap Cleaning for Small and Large Businesses
Whether you operate a food truck, a family-owned diner, or a large hotel kitchen in downtown Miami, grease trap cleaning is not optional. In fact, high-volume establishments may need monthly cleanings, while smaller operations might get by with quarterly service.
Even ghost kitchens and catering companies must adhere to grease management practices if they use commercial kitchen space.
Final Thoughts
Grease trap cleaning in Miami isn’t just a behind-the-scenes chore—it’s a vital part of running a clean, safe, and compliant food service business. Ignoring this responsibility can result in plumbing disasters, financial penalties, and damage to your brand.
