Massive sewer accumulations of fats, oils and grease are on the rise. The system impact of FOG is greatly exacerbated by a vast array of solid consumer products, namely so-called “flushable” wipes, that also accumulate in the sewer.
Often, the FOG deposits combine with the improperly disposed solid debris (including personal care products, wipes and trash) creating a heterogeneous conglomeration — called a fatberg — that can evolve into a significant blockage of the sewer, causing backups and sewer overflows, exposing humans and the environment to raw sewage.
