Understanding Carmel's FOG Regulations
Carmel's wastewater ordinances are designed to prevent sewer overflows and infrastructure damage caused by accumulated grease. The primary rule mandates that facility owners and users are responsible for maintaining their grease control equipment to prevent discharges that could interfere with the sewer system 1 2. This means all kitchen wastewater from sources like pot sinks, prep sinks, three-compartment sinks, dishwashers, mop sinks, and floor drains must be routed through an approved grease interceptor or trap 3 4. These devices must be easily accessible for service and inspection; outdoor interceptors cannot be located in a public right-of-way 1.
A cornerstone of the local code is the "25% rule." Both indoor grease traps and larger outdoor grease interceptors must be pumped out before the combined volume of FOG and settled solids exceeds 25% of the unit's liquid capacity 1 5 6. Allowing accumulation to exceed this level is a violation and increases the risk of grease escaping into the sewer lines. Furthermore, the use of chemicals, enzymes, or other additives designed to dissolve or emulsify grease is strictly prohibited, as these substances simply pass the problem downstream where the grease can re-solidify and cause blockages 7 3.
Required Cleaning Frequencies for Traps and Interceptors
The required pumping schedule is not one-size-fits-all; it depends on the type and size of your equipment and your kitchen's volume.
- Indoor Grease Traps: These smaller units, typically located under sinks, require much more frequent attention. The Carmel Utilities FOG manual recommends cleaning indoor traps weekly or as needed to ensure compliance with the 25% accumulation limit 1 8. For high-volume kitchens, weekly service may be a necessity.
- Outdoor Grease Interceptors: These larger, in-ground tanks are subject to a minimum pumping frequency of at least every 90 days (quarterly) 1 5. However, this is a minimum standard. Many establishments, especially those with high grease production, will require service more often-monthly or bi-monthly-to stay under the 25% threshold. The key is to have the interceptor pumped completely each time and refilled with clean water from the building's supply, not from the service truck's tank 1 6.
Best Practices for FOG Management
Beyond scheduled pump-outs, proactive in-house practices are vital for effective grease control and can extend the time between professional services.
- Scrape and Separate: Scrape all food solids from dishes, pots, and pans into the trash or compost before washing. Collect excess fryer oil and pan drippings in a separate container for recycling, rather than pouring them down the drain 2 3.
- Use Absorbent Materials: For grease spills in the kitchen, use absorbent pads or materials instead of hosing the grease into a floor drain 9.
- Maintain Access: Keep the manhole lids and access ports to outdoor interceptors clear of debris, equipment, or landscaping to ensure service technicians and inspectors can reach them easily.
- Clean Filters and Mats: Regularly clean grease filters in hood vents and grease-retaining mats in sink drains to prevent excess grease from entering the wastewater stream.
Inspection, Logs, and Enforcement
Carmel utilities officials conduct inspections to ensure compliance with FOG regulations 1 5. To prepare for these inspections, you are required to maintain a detailed logbook or manifest for your grease control equipment 1 7. This log should include records of every pumping service, showing the date, the company performing the work, the volume of waste removed, and the disposal location. Keeping these records on file is non-negotiable.
Enforcement actions can be taken for non-compliance. Consequences may include formal notices of violation, monetary fines, or mandates for increased maintenance frequency 1 7. In severe or repeat cases, the city may even require the removal of garbage disposals if they are contributing to the problem 2.

Cost Factors for Grease Trap Pumping in Carmel
The cost for professional grease trap and interceptor cleaning in Carmel varies based on several key factors. Generally, you can expect the following price ranges:
- Small Indoor Traps (15-50 gallon capacity): $150 - $300 per cleaning 10 11.
- Large Outdoor Interceptors (750+ gallon capacity): $350 - $1,000 or more per service 10 11.
The final price is influenced by the size and capacity of your unit, the level of buildup (heavily impacted units cost more), and physical accessibility. Additional costs can include local disposal fees and premium charges for emergency or after-hours service. Many service providers offer preventative maintenance contracts, which can provide significant savings-often between 10-20%-compared to scheduling one-time services, while also helping to ensure you never miss a required pumping date 10 11.
The Importance of Proper Disposal and Environmental Stewardship
Professional grease trap cleaning does more than keep you in regulatory compliance. Reputable service providers ensure that the collected FOG waste is transported and disposed of or recycled at approved facilities, such as rendering plants or anaerobic digesters. This process transforms a potential pollutant into resources like biodiesel, animal feed, or renewable energy. By choosing a responsible service provider, your business contributes to a circular economy and demonstrates a commitment to environmental stewardship, which aligns with the community values of Carmel.
