Understanding Westminster's Grease Interceptor Regulations
The City of Westminster has clear ordinances governing the installation and maintenance of grease control devices. Compliance begins with understanding the type of equipment you have and its specific requirements.
Interceptor Type and Placement: The city strongly prefers external grease interceptors that are easily accessible for service vehicles 1 2. These are typically larger, underground units located outside the building. Internal grease traps, which are smaller and located inside the kitchen, require prior approval from the city and are subject to much more frequent servicing schedules 3 4. A key rule is that no single grease interceptor may serve multiple business entities, ensuring clear accountability for maintenance 2.
Accessibility Requirements: Your interceptor, whether internal or external, must be readily accessible for inspection and pumping without moving equipment or using ladders 2. This means keeping the area around an external lid clear and ensuring indoor units are not blocked by storage or fixtures.
Mandatory Pumping and Cleaning Schedules
Adhering to a regular cleaning schedule is the cornerstone of compliance. Westminster's general guideline is that interceptors should be pumped when the combined grease and solids accumulate to 25% of the unit's volume 3. For most establishments, this translates to a cleaning frequency of every 1 to 3 months, or at least quarterly 1.
The schedule varies significantly by interceptor type:
- External Grease Interceptors: Typically require service every 1-3 months, depending on volume and usage.
- Internal Grease Traps: Due to their smaller capacity, these often require weekly to monthly cleaning and maintenance 1 5.
The most reliable method is to have a licensed hauler assess your specific operation and recommend a formal schedule, which you must then document and follow.
Record-Keeping and Documentation
Maintaining detailed records is not just good practice-it's a regulatory requirement for Westminster businesses. You must keep logs of all grease interceptor pumping, cleaning, and maintenance activities 1 5. These records should include:
- Date of service
- Name of the licensed hauler or company performing the work
- Volume of waste removed
- Disposal location or manifest number
- Signature of the service provider
It is advisable to retain these invoices and logs for a minimum of three years 6. They are your first line of defense during a city inspection, proving due diligence and regular maintenance.
Inspection, Enforcement, and Penalties
The Westminster Public Works Department is responsible for monitoring compliance with FOG regulations 1. Inspections can be routine or triggered by sewer line issues upstream from your business.
Common violations include:
- Failure to maintain a regular pumping schedule.
- Lack of required maintenance records.
- Improper interceptor placement or accessibility issues.
- Allowing grease to bypass the interceptor.
Penalties for non-compliance can include fines and mandatory corrective actions 2 7. Often, the most significant financial penalty is the need for an emergency cleaning of a severely neglected trap, which costs far more than routine service and may still be accompanied by city fines.

Cost of Grease Trap Services in Westminster
Service costs vary based on the size, type, location, and condition of your interceptor. Prices are generally higher for outdoor units due to their larger capacity and the equipment required.
Typical Cost Ranges:
- Regularly Maintained Indoor Trap: $175 - $475 per service visit 7 8.
- Regularly Maintained Outdoor Interceptor: $325 - $1,040 per pump-out 7 8 9.
- Emergency or Neglected Clean-Out: Costs can escalate quickly to $800 - $1,200 or more, as heavy sludge and solidified grease require more labor, time, and disposal fees 7 10.
Investing in routine maintenance is the most effective way to manage these costs. A consistently cleaned trap is faster and easier to service, keeping your per-visit fees at the lower end of the scale and preventing massive emergency bills.
Choosing a Licensed Service Provider
All grease waste must be handled by a licensed hauler permitted to operate in Westminster 1. When selecting a provider, ensure they are properly licensed and insured. It's wise to obtain multiple quotes that detail the scope of service, frequency, and all associated costs. A reputable provider will help you establish a compliant schedule and provide the detailed documentation you need for your records.
Actionable Steps for Compliance
- Identify Your Equipment: Confirm whether you have an internal grease trap or an external interceptor and verify its accessibility.
- Review Local Mandates: Contact the City of Westminster Public Works Department or review their online resources to confirm the exact requirements for your business 3 2.
- Schedule an Assessment: Have a licensed grease hauler evaluate your interceptor and recommend a formal pumping schedule.
- Establish Service Contracts: Secure a reliable service provider and set up a regular maintenance plan.
- Organize Documentation: Create a dedicated file or digital log for all service records and maintain them for at least three years.
Proactive management of your grease interceptor is a straightforward path to compliance, operational efficiency, and environmental stewardship in Westminster.
