The Tip Of The Fatberg: How FOG Affects Our Sewer System
Fats, oils, and grease (FOG) are significant contributors to sewer blockages, originating from both residential and commercial kitchens. When FOG is washed down the drain, it solidifies in cooler water, sticking to the pipes and leading to blockages. Over time, this can result in fatbergs—hardened masses formed when FOG combines with nonorganic materials like flushable wipes. While degreasers can temporarily liquefy FOG, they aren’t a long-term solution. Larger fatbergs often require hydro-jetting, a process using high-pressure water to break them apart.
Preventive measures are crucial for managing FOG buildup, such as proper grease trap maintenance and regular inspections. Innovative tools like the SL-RAT (Sewer Line Rapid Assessment Tool) help utilities quickly assess sewer conditions by using sound waves to detect blockages. This allows municipalities to identify problem areas before they lead to costly repairs or system failures. Regular evaluations and proactive cleaning, especially in high-risk areas, are key to preventing fatberg formation and maintaining a functioning sewer system.
