Bund

A bund is an embankment or wall of brick, stone, concrete or other impervious material, which forms the perimeter and floor of a compound and provides a barrier to retain a liquid.

Since the bund is the main part of a spill containment system, the whole system (or bunded area) is colloquially referred to as the ‘bund’.

Bunds should be designed to contain spillages and leaks of liquids used, stored or processed above ground and to facilitate clean-up operations, as well as being used to prevent pollution of the receiving environment, bunds are also used for fire protection, product recovery and process isolation.
