Above-ground vs underground grease traps: which suits the site better?
This decision is usually driven by layout, access, capacity and servicing practicality. The right answer depends on the kitchen and the wider site, not just on which option sounds bigger or more specialist.
Above-ground
Often easier when access, servicing and internal layout still work well
Above-ground systems can be a strong fit where the site has usable internal or plant-room space and where straightforward maintenance access matters as much as the initial installation.
Underground
More relevant when capacity, layout or external positioning push the job that way
Underground arrangements are often considered on larger or more constrained sites where a buried external system is more practical than forcing the whole solution inside the building.
What usually decides it
The real comparison factors
A sensible choice usually comes from comparing capacity, site layout, drainage arrangement and how the system will actually be emptied and serviced over time.
