Trenchlesspedia Explains Grease Trap

The presence of fats, oils and greases (FOGs) in a sewer system can cause problems. The effects of FOGs in a sewer line include partial or complete blockages, sewage backup, water contamination and slow drains. Residents are encouraged to minimize the presence of used greases and oils in their pipes by pouring them into containers. Restaurants, which typically produce a large amount of FOGs, use grease traps for this purpose.

Three types of grease traps include hydromechanical, gravity and automatic. Hydromechanical grease traps are typically smaller and less expensive, while gravity grease traps may have a capacity of 500 gallons or more. These two types need to be pumped out regularly, while an automatic grease trap has a mechanism for removing the grease automatically.

Sewer systems may contain grease traps in the branch lines to prevent FOGs from moving into the main lines. Trenchless techniques may be used in sewage pipes to clean, rehabilitate or replace pipes where grease traps have been absent or ineffective.
