Subject: Grease Interceptor sizing methodology.
Dear Sir/Madam,
The Grease interceptor is collecting grease from one sink with 3 compartments.
Each compartment is 10"W x 16.125"L x 10"D. The volume comes out to about 22 gallons.
From IMC section 1003; Table 1003.3.4.1 ( See below) for a 25 GPM flow rate 50 lbs. of grease
retention capacity is required. We have specified a grease interceptor for 25 GPM/ 64.9 Ibs of
grease retention capacity.
