Fats, Oils & Grease Program
Grease is a problem. In the sewage collection and treatment business, grease is singled out for special attention because of its poor solubility in water and its tendency to separate from the liquid solution. Large amounts of oil and grease in the wastewater cause trouble in the collection system pipes and the wastewater treatment plant. It decreases pipe capacity and, therefore, requires that piping systems be cleaned more often and/ or some piping to be replaced sooner than otherwise expected. Grease in a warm liquid may not appear harmful. But, as the liquid cools, the grease or fat congeals and causes nauseous mats on the surface of settling tanks, digesters, and the interior of pipes and other surfaces which may cause a shutdown of treatment plant units or messy backups in your home or business.
