Rules change; verify with your city. Summaries are plain-English restatements of the official source linked below; “Source says” shows the exact wording. Blank rows mean the sources we checked did not state that rule, not that there is no rule.

Required trap / interceptor type
Northbrook is in the Metropolitan Water Reclamation District of Greater Chicago (MWRD) service area, so the MWRD Sewage and Waste Control Ordinance applies along with the Illinois Plumbing Code. Northbrook adopts the Illinois Plumbing Code without a local grease amendment.
Illinois Plumbing Code (77 Ill. Adm. Code 890.510): commercial kitchens must have a grease interceptor with all grease-carrying fixtures directed to it; food waste disposers may not discharge into it, and water-cooled interceptors are prohibited.
MWRD Sewage and Waste Control Ordinance: discharges to MWRD sewers may not exceed 250 mg/L total fats, oils and greases (FOG).

Sizing rule
Illinois Plumbing Code minimum: the interceptor must hold at least half the liquid capacity of the connected fixtures on the same floor (60% if it sits on a floor below); fixture capacity in gallons = length × width × depth in inches ÷ 231.

Pumping / cleaning frequency
