Every commercial kitchen requires a grease interceptor to remove the grease from the sanitary system. However what a lot of restaurant owners do not know is that grease interceptors need cleaning and maintenance.
Photo below is of a grease interceptor that has been left for months uncleaned. Odour, corrosion, insects and vermin are a result of this fail.
As per Metro Vancouver GVSDD Bylaw No. 365, 2023:
10. Grease Interceptor Maintenance
10.1 Every grease interceptor must be examined and cleaned in accordance with this section 10.
10.2 A grease interceptor must be examined, and cleaned:
a. at least once every 90 consecutive days; or
b. when the total thickness of fats, oils and grease and solids in the grease interceptor is equal to 25% or more of the wastewater depth, whichever occurs earlier, or at any time or frequency that a Sewage Control Manager, by order, deems either sufficient or necessary to meet the purposes of section 1 of the Sewer Use Bylaw.
