Grease Interceptors & Traps 

Grease traps, also known as grease interceptors, are concrete vaults (hollow six sided structures) are placed below ground with piping.  Two manhole cover access points are placed at ground level.  The vault has a division down the middle that separates grease from water before allowing the water to continue on to the septic system or sewage lines.  Separating grease from water is crucial to prevent the grease from clogging the water pipes.  Grease traps are placed outside, generally in a roadway or parking lot, and are used with commercial kitchens or anywhere a large amount of grease and water are commingled.

Oldcastle Precast’s grease traps are manufactured in a variety of standard and custom sizes.  Knockouts, castouts, and special accesses can be added to your grease trap to to suit your particular project.
