Under Wisconsin Plumbing Code (SPS 382), food establishments here must control fats, oils & grease (FOG) with a grease interceptor or trap, and typically register with the local sewer/wastewater authority. Grease interceptors are required under the Wisconsin plumbing code, with FOG limits set by the municipal sewer utility.
Size the interceptor with our grease-trap sizing calculator, compare units in the grease-trap catalog, and confirm the local FOG permit with Waukesha County Department of Parks and Land Use - Environmental Health Division (licensing Agent of the WI Dept of Agriculture, Trade and Consumer Protection / DATCP) (contact above).
Hood fire suppression (Wisconsin adopts the IFC via SPS 314): commercial cooking under a Type I hood needs a wet-chemical suppression system to NFPA 96, permitted and inspected by the local fire marshal. Commercial kitchen hood suppression follows NFPA 96 as adopted through Wisconsin's fire and building codes, inspected by the local fire authority. See do I need a hood? and the hood CFM calculator.
Backflow prevention: Restaurants must install a testable backflow preventer (typically an RPZ) that is tested annually and reported to the local water utility. A certified backflow assembly (often an RPZ) on the water service, tested annually, is standard — confirm with your water utility.
