The legal answer
East Baton Rouge sets two hard limits (Sec. 2:273): clean at least every 90 days no matter how light your use, and never let grease and solids exceed one-third of the first stage. Whichever you hit first wins — and for most working kitchens, the one-third line arrives well before day 90.
The practical answer, by kitchen
| Kitchen type | Typical trap | Typical interval |
|---|---|---|
| Coffee shop / deli, little frying | 20–50 gal indoor | 4–8 weeks |
| Full-service restaurant | 50–100 gal indoor | 2–5 weeks |
| Heavy fry — seafood, wings, cajun | indoor trap | 1–3 weeks |
| Restaurant on an interceptor | 750–1,500 gal in-ground | 60–90 days |
| School / institutional kitchen | 1,000–3,000 gal | quarterly |
Typical ranges from industry practice, planning at 25% accumulation — a deliberate margin below the parish’s 33% ceiling. Your menu and covers decide your real number.
Your answer
The pumping frequency calculator turns trap size, daily covers, and menu grease-level into an estimated interval — and your first pump-out confirms it against what actually comes out of the tank. Signs you’ve waited too long: smells, slow drains, or in the worst case an overflow.
Set the interval once, never think about it again
