How Often You Must Clean It in Milwaukee
State 90-day maximum (SPS 382.34) applies; MMSD may require more frequent service based on load (under MMSD Rules, Chapter 11 (Discharge Regulations)). The industry-standard 25% rule applies either way: clean before fats, oils, and grease reach a quarter of your trap's capacity, because past that point grease passes straight through to the sewer. High-volume kitchens (fryers, BBQ, seafood) often need service more often than the minimum.
