Where in a building would a grease trap be located?

Generally it's directly under the space it serves (i.e. a kitchen or garage). Grease traps are typically cast into a slab. I have seen one case where it was outside the building, but that was because of a diesel sprinkler pump that was located away from the building that shared the trap.

does the location have anything to do with the inverts of the sewer system that serves the building ? or it doesn't matter and its always in the kitchen and if you need a ejector pump to make it work thats what you need to install?

What about an exterior grease trap?

Location can depend on a number of factors. Generally though, if it is for a small commercial kitchen, it is located in the kitchen.. either above ground or cast into the slab (assuming a main floor kitchen). It is best if they can flow into the sewer/drain via gravity and not require a force main. This limits long term maintenance and allows it to be used in the event of a power failure. If the facility creates a significant amount of grease, then an exterior grease trap can be used. The mechanical engineer would size the grease trap based on the plumbing loads and that may tell a team if it fits inside the building or if it requires so much space it needs to go outside. The inside/outside is typically driven by the size of the trap itself.

They can be small or big. small ones go under a sink with proper filters to reduce maintenance. Restaurants typically have a huge sludge bin outside to catch grease.
