Removal of grease from greasy wastes is necessary if the sewage system is to function properly. One way grease is collected is by ceramic or cast-iron grease interceptors installed inside mess halls. Among the types of interceptors you may encounter is the Zurn interceptor shown in figure 5-8. Another way of collecting grease is to use concrete or brick grease traps outside of buildings. Mess personnel usually clean the inside interceptors but you may have to clean the outside traps. When inside grease interceptors are maintained properly, they should collect most of the grease from the waste. They may need cleaning once each day.
Remember that outside grease traps are intended to serve kitchen plumbing fixtures and equipment only. So they should never be connected to soil and waste lines from toilet rooms. To help ensure proper functioning, clean grease traps at least once a week. Since accumulated odor-forming solids cause septic action within a short time, remove all solids each time the traps are cleaned.
The steps of the procedure for cleaning outside grease traps include the following:
1. Skim grease from the surface of the trap using an ordinary perforated sewer scoop, and place it in suitable containers for disposal.
