Understanding Local Grease Trap Regulations
In Billings, as in most municipalities, all food service establishments connected to the public sewer must have an approved grease removal system. This is typically a grease trap for smaller fixtures or a larger grease interceptor for high-volume kitchens 1 2. The primary goal of these regulations is to prevent FOG from entering and solidifying in the city's sewer lines, which can lead to severe blockages, sanitary sewer overflows, and expensive public works repairs.
The Billings Public Works department sets the standards for these systems and their maintenance 3. Compliance isn't optional; it's a condition of your operation. Local providers familiar with Billings' codes, such as Cotter's Sewer and Andersen Sewer Service, can help you determine if your current setup meets specifications and advise on any necessary upgrades 4 5.
Mandatory Cleaning Frequency and Compliance Triggers
How often you need professional grease interceptor pumping is not a guess-it's defined by both capacity and accumulation. The universal rule requires cleaning when the combined FOG and solids accumulate to 25% of the unit's volume 1 2. For many establishments, this point is reached approximately every three months, making quarterly service a common standard.
However, high-volume kitchens, such as those in busy restaurants, cafeterias, or bakeries, will likely require monthly or even more frequent service to stay compliant and functional 1. The only way to know for sure is through regular inspection. Neglecting this schedule until a drain backs up is a recipe for an emergency service call, potential health code violations, and significantly higher cleaning costs.
The Critical Role of Record Keeping
One of the most overlooked yet vital aspects of grease management is documentation. Billings Public Works or health inspectors can request to see your maintenance records at any time 1 3. A proper service record should include:
- The date of each grease trap cleaning or pumping.
- The volume of grease and solids removed (in gallons).
- The name and contact information of the service provider.
- The disposal method or location for the collected waste.
Maintaining a detailed logbook or file of invoices from your service provider is your first line of defense during an inspection, proving due diligence and ongoing compliance.
What to Expect During a Professional Service Visit
A thorough grease trap cleaning involves more than just skimming off the top layer of oil. A professional service from a local Billings company will typically follow a process designed for complete waste removal and system inspection:
- Pumping: Using a vacuum truck, the technician will remove all liquid and solid contents from the trap, including water, grease, and food solids.
- Scraping and Cleaning: The interior walls and baffles of the trap are scraped and cleaned to remove hardened grease buildup.
- Inspection: The trap, its components, and the inlet/outlet lines are inspected for damage, leaks, or potential issues.
- Proper Disposal: The collected FOG is transported to an approved facility, such as a wastewater treatment plant or rendering facility, for legal disposal or recycling.
- Documentation: You receive a detailed service report for your records.
Companies like Andersen Sewer Service and others in the area may offer inspection services as part of a regular contract, providing peace of mind 5 6.

Cost Factors for Grease Trap Pumping in Billings
The price for grease trap maintenance in Billings varies based on several key factors. Understanding these can help you budget effectively and avoid surprises.
- Trap Size and Type: A small under-sink grease trap costs less to clean than a large, in-ground concrete interceptor.
- Accessibility: Easily accessible traps in a kitchen or directly outside a building are less expensive to service than those buried under concrete or located in tight, difficult-to-reach areas.
- Level of Maintenance: A trap cleaned on a regular schedule will be far less costly than one that is severely neglected and requires extensive scraping and possible repairs.
- Service Frequency: Committing to a regular monthly or quarterly schedule often comes at a lower per-visit rate compared to one-time emergency calls.
- Volume of Waste: The amount of grease and solids to be removed directly impacts the time and disposal costs for the provider.
For a well-maintained, standard indoor grease trap on a scheduled service plan in Billings, you can expect costs to start in the range of $175 to $225 per visit 1 7. One-time cleanings for smaller units may range from $125 to $240+, while larger, neglected, or hard-to-access systems can cost $475 or more for a single service 1 8 9 10. The most accurate way to determine your cost is to get a site-specific quote from a local provider.
Consequences of Non-Compliance
Failing to maintain your grease trap has serious repercussions. Inspections by Billings Public Works can result in violations if your trap is overfull or records are missing 1 3. Enforcement actions typically begin with warnings but can escalate to significant fines and, in persistent cases, orders to cease operations until the issue is rectified. Furthermore, a grease-caused sewer backup on your property or into the city main can lead to costly cleanup bills, damage to your reputation, and even liability issues.
Choosing a Service Provider in Billings
When selecting a company for grease interceptor pumping, consider more than just price. Look for a provider with:
- Local Knowledge: Familiarity with Billings Public Works requirements is essential.
- Reliability: Consistent, on-time service is crucial for maintaining your schedule.
- Proper Licensing and Insurance: Ensure they are licensed to handle and transport liquid waste in Montana.
- Transparent Documentation: They should provide clear, detailed service reports for your compliance file.
- Range of Services: Some companies, like Cotter's Sewer, also offer related services such as septic system maintenance, which can be convenient for some businesses 4.
Taking the step to contact local providers for an assessment and quote is the best way to ensure your establishment remains in good standing 3 4 5 11.
