Cleaning Frequency for Grease Interceptors
Depends on facility’s service volume
Depends on size of grease interceptor
At a minimum, pump complete contents of interceptor every 90 days
Based on studies conducted for pollutant concentrations, depth of FOG layer and food solids layer effecting efficiency of interceptor
Some facilities will have to pump every 60 days or every 30 days
Make sure plumber and grease waste hauler leave the grease interceptor with all proper components…Outlet T, Inlet T, Midwall baffle sweep. Its not just about pumping the interceptor
For facilities that have excess flour, dough, batter…will need to pump interceptor more often. Observe the 25% rule.
Also, food grinders are definitely discouraged. They contributeto pipe blockages and fill up the interceptor with food solids and make it inefficient
