The Latest in FOG News

Hot grease being poured directly from a cooking pan down the drain of a kitchen sink.

It’s long been known that the place to dispose of fats, oil, and grease for private individuals or small businesses is not down the kitchen sink or other plumbing, whether that plumbing is connected to a sewer system or a septic system. And yet, the issue of FOG (fats, oil, and grease) clogging up wastewater systems remains a worldwide issue. 

For those involved in the wastewater field, the unpleasant reality of FOG buildup and the massive fatbergs it can lead to is part of day-to-day life, and it probably isn’t something anyone wants to spend more time thinking about than necessary. But widely sharing the stories of why FOG pollution is such an issue might be one of the best things we can do to help homeowners and industries to reverse the tide of inappropriate substances flushing into wastewater systems. And, as technology advances, more and more technological solutions for FOG management are being explored!

In this post, we’ve collected links to recent news stories covering FOG challenges in municipal sewer systems, both domestically and internationally. Consider sharing them with people you meet who might not know why they shouldn’t put bacon grease down the drain or flush their wet wipes, and find some hope in the pursuit of technological fixes!

Featured Video: Lift Station 2 Pump Cleaning

Lift stations are designed to move sewage from a lower to higher elevation through pumps and pipes. Once pumped to a higher elevation, sewage continues to move through the collection system via gravity to reach the wastewater treatment plant. Utilities typically install one of two types of lift stations. Submersible pump lift stations, also called wet well lift stations, contain the pumps, sewage, and floats all in one vault. Dry well lift stations use two vaults to separate the pump system and wastewater. To learn more about lift station operations, components, sizing calculations, inspections, maintenance, emergency response, and pump selection for both types, check out the U.S. EPA’s Wastewater Utility Operation and Management for Small Communities – Lift Station Overview webcast recording.

Learning the theory behind lift station operations, maintenance, and emergency response is an essential component to any wastewater operator’s training, however hands-on experience is also important. While we can’t give you hands on experience in a blog post, the following video offers a real world example of lift station maintenance. In this video, a Minnesota operator demonstrates how to remove debris from a clogged pump at his facility’s lift station. He also overviews the various components on the lift station control panel. Please note that when troubleshooting lift stations you should first be trained in operator safety. Safety topics to review before working with lift stations include lock out tag out, confined space, electrical safety, fall protection, crane safety, and tail gate safety.
