Sewer capacity reduction, increased maintenance costs, shortened infrastructure lifespan, sewer overflows and backups, odor and many other issues to the environment are a few of the reasons why FOG is a problem.

Most wastewater collection system blockages can be traced back to FOG as the cause. Blockages in the wastewater collection system are serious, causing sewage spills, manhole overflows and sewage backups in homes and businesses.

Large amounts of FOG in the wastewater causes decreased pipe capacity in the collection system, resulting in increased maintenance costs and premature pipe replacement.

FOG also can cause treatment issues at the wastewater treatment plant. In a liquid form, it does not appear harmful. As the liquid cools and the grease congeals, it creates thick grease mats on tanks, piping and equipment, which causes treatment problems and higher maintenance costs.
