Sewer back-ups and overflows are frequently caused by improper materials such as fats, oils and grease (FOG) being placed into the sewer system. Since fats, oils and grease are lighter than water; they tend to accumulate at the top and sides of sewer pipes and can build up until a blockage occurs. They also tend to solidify as they cool inside pipes. If a blockage occurs, the sewer backs up or overflows resulting in property and environmental damage.
Keeping FOG from going down the drain isn't just about the sewer system, though. It can save you money too! Most sewer back-ups occur between the house and the City's sewer main, where the property owner is responsible for correcting the problem.
