While most communities have instituted FOG abatement programs at the commercial level and education programs for consumers, few are addressing what happens to Grease trap waste once it is collected. This can result in grease getting dumped untreated into sewer systems and causing sanitary sewer overflows. Rising disposal costs have led some municipal governments to subsidize tipping fees in an attempt to prevent illegal dumping, with limited success. In the U.S., approximately one of every two dollars allocated to sewer line maintenance is spent to repair grease clogs and other grease-related damage. This translates into a $25 billion headache annually.
