GREASE……really is a problem!
Grease is “hydrophobic” which means it prefers to cling to surfaces that are free of water.
Large amounts of oil and grease in wastewater can cause sewer lines to clog, sewer lift station failures, wastewater treatment plant problems and environmental concerns. Grease builds from the top down in the sewer line while heavier debris collects on the bottom as the wastewater flows through the sewer pipe. Grease build-up restricts the flow of wastewater. Sometimes, grease layers will break off and create a downstream plug. Eventually, grease will lead to costly and dangerous backups. When sewer pipes get clogged:
Residual fats, oils, and grease (FOG) are by-products that food service establishments must constantly manage. Typically, FOG enters a facility’s plumbing system from washing dishes/pots, floor cleaning, and equipment cleaning.
Sanitary systems are NOT designed or equipped to handle the FOG that accumulates on the interior of the sewer collection system pipes. Over 30% of our 2000 sanitary sewer blockages were the result of FOG build-up from residential, institutional, and commercial sources.
