Frequently Asked Questions (FAQ)

Question:
We are designing a commercial kitchen for the Army Corp which will have a LA County approved grease trap (2,000 gallons). Right now we have the dishwasher and garbage disposal connected to the grease trap. Is this arrangement allowed?

Answer:
Thank you for your inquiry. Is the commercial kitchen within the Unincorporated Area of LA County or in any contract city that referred you over to LA County DPW? If so, then the dishwasher and garbage disposal unit are not allowed per the Uniform Plumbing Code.
