§ 18.21.210 — Design standards for grease traps

18.21.210 - Design standards for grease traps.

A. Installation. Grease traps shall be used on kitchen wastelines from institutions, hotels, restaurants, schools with lunchrooms, and other places that may discharge large amounts of greases and oils to the sewer. However, wastes from garbage grinders must not be allowed to enter a grease trap. The trap shall be installed near the plumbing fixture that discharges greasy wastewater and should be easily accessible for cleaning. When maximum efficiency grease removal is necessary, a dual chambered trap that separates, then stores grease shall be utilized. If the dual chamber trap is installed as close as possible to the source of hot greasy wastes, the separated grease can be conveyed to the secondary chamber, where it accumulates, cools, and solidifies. B. Sizing. Grease trap sizing will depend on the particulars of the application. Building code authorities and trap manufacturers should be consulted prior to sizing the unit. Grease interceptors shall be sized using Chapter 18.20 of this Code.
