Why Grease Trap Regulations Matter in California
California enforces some of the strictest environmental and wastewater regulations in the United States. That’s because grease-related sewer overflows are one of the leading causes of wastewater pollution, property damage, and public health hazards across the state.
On entry of the fats, oils and grease in the sewer system:
They harden and stick to pipes
They restrict water flow
They cause sewer backups
They create foul odors
They attract pests
They contaminate waterways
According to municipal wastewater authorities, FOG-related blockages account for more than 70% of sewer overflows in some California cities.
That’s why grease traps and proper used cooking oil collection are not optional.
What Is a Grease Trap and Why Is It Required?
A grease sap (grease interceptor, grease trap) is a plumbing equipment that is intended to:
Capture fats, oils, and grease
Prevent FOG from entering sewer lines
Separate grease from wastewater
Protect municipal sewer systems
Grease traps are legally required for food-service establishments because dishwashing, cooking, and food prep generate large amounts of grease-laden wastewater.
Without a grease trap, your kitchen would be directly violating California plumbing and environmental laws.
California’s FOG Problem Explained
California’s dense population, high restaurant volume, and aging sewer infrastructure make it especially vulnerable to FOG-related damage.
Major cities like Los Angeles, San Francisco, San Diego, and Sacramento spend millions of dollars every year repairing sewer lines clogged by grease.
To combat this, California introduced aggressive FOG control programs that include:
Mandatory grease traps
Required cleaning schedules
Strict disposal methods
Enforcement inspections
Heavy fines for violations
These regulations work hand-in-hand with waste cooking oil collection service providers to keep grease out of drains.
Statewide vs Local Grease Trap Regulations
California sets statewide standards, but local municipalities enforce their own specific requirements.
Statewide Oversight Includes:
California Plumbing Code (CPC)
State Water Resources Control Board
Environmental Health Departments
Local Authorities May Regulate:
Grease trap size
Cleaning frequency
Disposal methods
Documentation requirements
Approved service providers
This means a restaurant in Los Angeles may have different rules than one in Fresno even though both follow state law.
Who Is Legally Required to Have a Grease Trap?
If your business prepares, cooks, or serves food, you almost certainly need a grease trap.
This includes:
Restaurants
Cafés
Fast-food chains
Bakeries
Food trucks
Commercial kitchens
Catering facilities
Hotels with kitchens
Schools & universities
Hospitals
Grocery store delis
Even low-volume kitchens may still require grease control systems.
Grease Trap Size and Installation Requirements
California regulations require grease traps to be:
Properly sized for kitchen output
Installed by licensed professionals
Accessible for inspection and cleaning
Designed to handle peak flow
An undersized grease trap is considered non-compliant, even if it’s cleaned regularly.
Improper installation can also lead to:
Failed inspections
Immediate citations
Forced retrofits
Temporary closure
Grease Trap Cleaning & Maintenance Laws
One of the most critical regulations you cannot ignore is cleaning frequency.
Most California municipalities require grease traps to be cleaned:
Every 30–90 days
Or when grease reaches 25% capacity
Failing to meet cleaning schedules is one of the top reasons restaurants are fined.
Cleaning must be done by licensed professionals, and waste must be disposed of properly not dumped or rinsed away.
Record-Keeping and Documentation Requirements
California law requires businesses to maintain grease trap service records.
These records must include:
Date of service
Service provider name
Amount of waste removed
Disposal method
Technician signature
Records must be available during inspections.
Lack of documentation = non-compliance, even if cleaning was done.
Fines, Penalties, and Legal Consequences
Ignoring grease trap regulations can be extremely costly.
Common Penalties Include:
Fines ranging from $500 to $10,000+
Mandatory plumbing repairs
Sewer damage liability
Business license suspension
Temporary or permanent closure
Environmental violation records
Repeat offenders face escalating penalties.
The Role of Used Cooking Oil Collection
Many restaurant owners mistakenly believe grease traps handle all oil waste. They don’t.
Grease traps capture FOG from wastewater, but used fryer oil must be handled separately through professional used cooking oil collection services.
Pouring fryer oil into sinks even with a grease trap is illegal.
Proper used oil handling:
Prevents trap overload
Reduces cleaning frequency
Keeps you compliant
Supports recycling efforts
Waste Cooking Oil Collection Service vs Grease Trap Cleaning
These two services work together but are not the same.
Waste Cooking Oil Collection Service
Handles fryer oil
Uses sealed containers
Oil is recycled into biodiesel
Scheduled or on-demand
Grease Trap Cleaning
Removes grease from wastewater systems
Prevents sewer blockages
Required by law
Using both services ensures full compliance.
