There is FOG in the sewers –but it’s not that misty stuff that fills the air. The term “FOG” stands for fats, oils and grease. Originating in our kitchens, it clogs sanitary sewer systems across Hampton Roads and is a harmful threat to the environment. When poured or washed down the drain, FOG builds up on pipe walls, restricting the flow of wastewater exiting our home’s plumbing. Over time, FOG leads to blockages that result in overflows into our homes or onto our streets, down storm drains, and into local waterways, all posing a serious risk to public health.
