Grease Interceptor Requirements


​Metro Vanc​ouver’s Food Sector Grease Interceptor Bylaw 268 requires commercial and institutional kitchens to install and maintain a grease interceptor to reduce fats, oils and grease (FOG) in the sewer system.

Fats, oils and grease in the sewer system costs the region over $2.7 million each year. They can clog sewers and cause back-ups into homes and businesses, and overflows into the environment.

​Who does the​ bylaw apply to?

This bylaw applies to commercial kitchens and operations that prepare, package, serve, sell or otherwise handle food in a way that ​produces fats, oils and grease. This includes: restaurants, fast-food operations, cafeterias, hospitals, bars, grocery stores, bakeries, coffee shops, butcher shops, and other similar operations that handle food.

Main ​bylaw requirements

If you operate a commercial or institutional kitchen, you must:

  • Install a correctly sized grease interceptor that is connected to all required fixtures
  • Maintain the grease interceptor by having it pumped out by a service provider
  • Ensure that what is coming out of the grease interceptor meets bylaw limits
  • Keep records of grease interceptor cleanouts and maintenance activities

Viola​tions may result in re-inspection fees of up to $300 or a fine. Certain violations — such as not having a grease interceptor — carry a minimum fine of $2,000.​
