Lift Station and Sewer Line Grease

It’s no secret where grease comes from that builds up in lift stations, wet wells, and sewer lines.  Who does not like to eat greasy food?   Whether it comes from cooking a steak or frying bacon and eggs, the grease has to go somewhere. Some of us collect it, some rinse it off.  Many restaurants have undersized grease traps and the scalding hot water just moves the grease down the line.  For many of us, getting a pump truck to suck the grease out of a lift station just isn’t practical.   As operators we need methods that are affordable and wonderfully effective.

Aquafix’s grease control products
are great alternatives to Red Hot Sewer Solvent. Red Hot is an extremely dangerous granular or liquid hot solvent that uses caustic soda to heat up and melt grease. This proposes problems downstream as the grease will cool, solidify, and enter the wastewater treatment plant. We strongly recommend our products as safe alternatives.


7 Facts about Grease in Collection Systems and Sewer Lines

  1. The harder and colder the water, the harder the grease will set up on the walls.
  2. Generally animal fats are more difficult to break up than vegetable fats with the exception of coconut oils.
  3. The thicker the grease is on the walls of a lift station, the more grease in the sewer lines, especially in hilly areas.
  4. Grease coats the lines and creates anaerobic pockets for converting sulfate salts into hydrogen sulfide gas.  Sulfide causes rotten egg odors and sulfuric acid corrosion of sewer lines.
  5. The less BOD in a sewer line, the less sulfide gas formation.
  6. 1/2 inch of grease in an 8” line reduces your flow by 25%.   Then your pumping costs go up accordingly.
  7. Grease causes 30% of sewage backups.
