Running a successful restaurant in Bellingham requires more than great food—it demands proper grease management to avoid costly plumbing disasters, health code violations, and business interruptions. Understanding grease trap maintenance and disposal requirements protects your investment and reputation.

Understanding Grease Trap Requirements

Whatcom County Regulations: Local health departments mandate grease management systems for all food service establishments.

Required installations:

  • Grease traps: For smaller operations (under 50 seats)
  • Grease interceptors: High-volume kitchens
  • Capacity sizing: Based on fixture count and flow rates
  • Location requirements: Accessible for maintenance
  • Inspection standards: County health department oversight

Sizing Requirements:

  • Small café: 20-40 lb. trap
  • Family restaurant: 50-100 lb. trap
  • Full-service dining: 750-1,500 gallon interceptor
  • Fast food: 1,000-2,000 gallon interceptor
  • Institutional kitchen: 1,500+ gallon interceptor


Undersized traps cause frequent backups and code violations, while oversized units waste money and space.

Grease Management Failures: More Than Just a Mess

Direct Financial Impact:

  • Emergency plumbing repairs for blockages
  • Fines from the health department
  • Daily revenue loss from business closures
  • Expensive sewer line replacements
  • Damage to your business reputation, which can be priceless

Hidden Costs Often Overlooked:

  • Increased pest problems
  • Employee overtime during emergencies
  • Customer compensation for disruptions
  • Higher insurance premiums
  • Lost repeat business


One preventable backup can cost more than years of proper maintenance.

Best Practices for Daily Operations

Kitchen Staff Training Essentials:

Proper Disposal Methods:

  • Scrape plates before washing
  • Wipe pans with paper towels
  • Use strainer baskets religiously
  • Never pour oil down drains
  • Cool and contain grease for disposal

Temperature Management:

  • Run cold water when draining greasy equipment
  • Hot water liquefies grease temporarily, causing downstream problems
  • Maintain water heater at 140°F for sanitization
  • Train dishwashers on proper techniques

Cleaning Protocols:

  • Empty drain screens every shift
  • Clean floor drains nightly
  • Maintain grease trap baffles
  • Document all cleaning activities
  • Assign specific responsibilities

Grease Trap Maintenance Schedule

Daily Tasks:

  • Seasonal variations


25% Rule: When combined grease and solids reach 25% of the interceptor capacity, pumping is required.

Keep records for minimum three years for compliance verification.

Ask The Experts

  • How often should our 75-pound grease trap be pumped if we serve 200 meals daily?

    With that volume, monthly pumping is minimum, but you'll likely need bi-weekly service. The real answer depends on your menu—high-grease items like fried foods and creamy sauces require more frequent service. Start with bi-weekly and adjust based on accumulation rates.

  • Can enzyme treatments replace mechanical cleaning and pump-outs?

    No, enzymes supplement but don't replace mechanical cleaning. While enzymes help break down grease between services, they can't remove solids or handle heavy accumulation. Think of enzymes as preventive medicine and Hot Jetter service as necessary surgery—both have important roles.
