The person who made your barrel watertight before 'quality control' was a department.

means A craftsman who makes or repairs wooden casks and barrels by fitting and binding shaped staves together.

from From Middle English couper, borrowed from Middle Dutch/Middle Low German kūper, itself built on kūpe meaning 'cask' or 'tub' — a word going back to Latin cupa, 'tub, vat' (the same root that gives us 'cup'). The surname Cooper comes straight from the trade, one of many English last names (Smith, Baker, Mason) that simply announce what your ancestors made for a living.
