Recent changes to grease interceptor sizing by Metro Vancouver have led to a relaxation of what may connect into a grease interceptor. Below is a short list of what DOES NOT need to connect into a grease interceptor any longer:
- Bar Sinks
- Glass Washer
- Espresso Machine
Further on online sizing app allows the user to calculate the size of their new grease interceptor. Here is the link to Metro Vancouvers grease interceptor sizing chart: http://www.metrovancouver.org/Includes/grease/index.html
We get a lot of questions about this. Simply put a non-simultaneous load means that the fixture must still connect to a grease interceptor but DOES NOT ADD to the size of a grease interceptor. Below is a list of fixtures that must connect to a grease interceptor but does not add to the total size. Only exception is if the fixture below has a LARGER flow rate than the other fixtures draining to the grease interceptor then IT’S low rate must be used.
- Floor drain
- Trench drain
- Mop sink
- Self-Cleaning kitchen exhaust hood
Exception to this is if the floor drain has a dedicated sanitary discharge say from a wok. The understanding here is that the floor drain (and trench drain) are used after hours for cleaning.
