When FOG is dumped down the drain, it forms large, thick grease balls that clog pipes. Clogged pipes can result in sewer backups and spills, create environmental problems, and damage property leading to costly repairs. FOG includes items such as cooking oils, salad dressings, sandwich spreads, meat juices, meat fat and other similar products, eventually results in sewer backups that can overflow onto streets and even into the home, damaging properties and the environment. Remember that every household plays an important role in preventing neighborhood sewer blockages.
