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.
INTERCEPTORS AND GREASE TRAPS
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
