Grease Trap Cleaning That Keeps You Inspection-Ready
In the Atlanta area, grease trap maintenance plans should be tailored to comply with local FOG regulations. Inspections are often unannounced, and just having a recently cleaned trap doesn’t guarantee a passing grade.
Southern Green Industries provides grease trap cleaning with documentation and consistency in mind, helping facilities stay prepared for inspections with:
Cleaning frequency that aligns with actual usage and local requirements
Adherence to the 25 percent rule
Complete and accessible manifests
Full removal of grease and solids during service
Consistency across service visits
With predictable scheduling and thorough service, your facility will be better positioned to stay compliant, avoid re-inspection fees and reduce the risk of operational disruptions tied to grease management issues.
Grease Trap and Interceptor Types We Service
Southern Green Industries provides grease trap cleaning and maintenance for a wide range of system types, from small indoor units to large outdoor interceptors. Service requirements vary based on design, capacity and location, and each system type requires a slightly different approach to ensure it is fully cleaned and functioning as intended.
Common systems we service include:
Under-Sink Grease Traps (Hydromechanical Units)
Typically found inside kitchens near sinks or dishwashing stations. These smaller units fill quickly and often require more frequent service to remain compliant.
Indoor Grease Interceptors
Larger than under-sink traps and often located in utility rooms or floor-level access points. These systems handle higher flow rates but still require consistent maintenance due to limited capacity.
Outdoor In-Ground Grease Interceptors
High-capacity systems designed to serve full commercial kitchens. These interceptors separate and store large volumes of fats, oils, grease and solids, and must be serviced at regular intervals to remain compliant with local FOG regulations, including the 90-day minimum and 25 percent rule.
Multi-Tank and High-Volume Systems
Facilities with heavy production, multiple kitchens or shared infrastructure may operate multi-compartment or multi-tank interceptors. These systems require coordinated service to ensure each chamber is fully evacuated and inspected at the necessary frequency to avoid compliance penalties.
If your facility operates more than one system, or if your layout includes a combination of indoor and outdoor units, Southern Green Industries can build a service plan that accounts for each component without disrupting operations.
Commercial Facilities We Serve
Southern Green Industries works with a broad range of commercial and institutional kitchens throughout the Atlanta area, including:
Restaurants, from quick-service to full-service dining
Ghost kitchens, commissary kitchens and shared kitchen spaces
Hotels and hospitality facilities
Healthcare facilities and hospital kitchens
Schools, universities and large cafeterias
Food halls and multi-tenant retail properties
Catering operations and production kitchens
Facilities with shared plumbing systems, high-volume production or nontraditional layouts often face additional challenges, including increased grease load, limited access or coordination between multiple tenants. In these environments, consistent service and clear documentation become even more important to avoid backups, disputes or compliance issues.
Frequently Asked Questions About Grease Trap Cleaning in Atlanta
What are the Atlanta metro area’s primary grease trap regulators?
- Atlanta: City of Atlanta Watershed Protection Grease Management
- Fulton County: Fulton County Commercial Pretreatment
- Clayton County: Clayton County Water Authority
- Cobb County: Cobb County Water System Grease Management
- Dekalb County: Dekalb County FOG
- Gwinnett County: Gwinnett County FOG
How often does a grease trap need to be cleaned in Atlanta?
Indoor grease traps are generally required to be cleaned at least every 14 days in Atlanta, while outdoor interceptors must typically be serviced at least every 90 days. High-volume kitchens often need more frequent cleaning to stay within the 25 percent capacity compliance limit.
What is the 25 percent rule for grease traps?
The 25 percent rule means that the combined volume of FOG cannot exceed 25 percent of the trap’s total capacity. If it does, the system is considered noncompliant, even if it is still draining properly.
What happens if my grease interceptor fails an inspection?
You may receive a notice of non-compliance and be required to correct the issue within a set timeframe. Re-inspection fees, increased scrutiny and potential fines can follow if the issue is not resolved.
Do I need to keep grease trap cleaning manifests on-site?
Yes. Inspectors often request manifests during inspections, and they must be accessible for review. If you cannot show that cleaning has been performed at the required frequency, you can face violations even if the trap is currently in acceptable condition.
How long should grease trap records be retained?
Most facilities are expected to keep records for at least three years. Keeping organized, accessible documentation helps demonstrate consistent compliance during inspections.
How do I know if I need more frequent grease interceptor pump-outs?
Frequent odors, slow drainage or grease accumulation approaching capacity between service visits are common indicators. Your grease interceptor service provider should also be able to measure grease and solids levels and advise if your system is nearing or exceeding the 25 percent threshold and needs a shorter cleaning interval.
What happens if a grease trap is not cleaned regularly?
Grease and solids can build up, reducing capacity and allowing FOG to enter sewer lines. This can lead to backups, odors, compliance issues and potential fines.
Why does my grease trap smell even after cleaning?
Persistent odors after service may indicate structural issues, excessive solids buildup or improper flow within the system. In some cases, odors are tied to venting or hydraulic conditions rather than cleaning frequency alone.
Can a full grease trap cause backups or downtime?
Yes. When a trap reaches capacity, grease and wastewater can back up into sinks or floor drains. This can disrupt kitchen operations and may require emergency service.
Will grease trap issues affect my business insurance coverage?
They can if grease trap and FOG issues lead to damage. Many policies exclude damage caused by poor maintenance or gradual buildup, which means claims for FOG-related backups may be denied. If a failure affects neighboring units or shared plumbing systems, it can also lead to liability claims depending on the circumstances and policy coverage.
What’s the difference between a grease trap and a grease interceptor?
Grease traps are typically smaller, indoor units located near fixtures, while interceptors are larger, often outdoor systems designed to handle higher volumes. The terms are often used interchangeably, and both serve the same function of separating fats, oils and grease from wastewater.
Do indoor grease traps need to be cleaned more often than outdoor interceptors?
Yes. Indoor traps are smaller and fill more quickly, which makes more frequent cleaning necessary in practice. This is also why they are subject to shorter required service intervals. Outdoor interceptors have greater capacity but still need regular service to remain compliant.
Do I need to shut down my kitchen during service?
In most cases, full shutdown is not required, but limiting water use during pumping is often necessary. Scheduling service during slower periods or after hours can help minimize disruption.
Can service be scheduled after hours or off-peak?
Yes. Many facilities choose after-hours or off-peak scheduling to avoid interfering with kitchen operations. Availability may depend on site access and service requirements.
What access is required for grease trap pumping?
Pump trucks need clear access to the interceptor or trap, including reachable lids and unobstructed hose paths. Locked gates, blocked access points or long distances from parking areas can affect service time.
Can I switch grease trap service providers without compliance issues?
Yes, but the transition should be handled carefully to avoid missed cleanings or gaps in documentation. Maintaining service continuity and transferring records is key to staying compliant.
