Who issues/enforces it. Detroit Water and Sewerage Department (DWSD) (City layer).
When you need it. Ongoing.
How to comply. Clean the interceptor when it reaches 25% capacity ("25% rule") — high-volume Detroit kitchens typically clean every 1–3 months; use a licensed hauler and keep a waste manifest documenting proper FOG disposal after each pump-out. Confirm your specific requirements with DWSD (⟢ VERIFY).
Cadence. 25% rule (commonly every 1–3 months).
