Grease in Pipes: Fats - Oils - Grease

Facts about Fats, Oils and Grease

Fat – Oil – Grease (FOG). Fats, Oil & Grease can accumulate in a building’s private sanitary sewer lateral or a City owned public sanitary sewer pipe in the street. This can cause blockages in pipes, as well as causing a sewage back-up into your property. When hot dishes and pans containing Fats, Oil or Grease are washed without proper removal processes, this will harden downstream, causing blockages, and reducing the capacity of the pipes. This can lead to expensive maintenance & repair costs!
