noun. An aqueduct in France. An aqueduct in France. In anatomy, an aqueduct is defined as a tube that liquids pass through.
Aqueducts also provided water for mining operations, milling, farms and gardens. Aqueducts moved water through gravity alone, being constructed along a slight downward gradient within conduits of stone, brick or concrete. Most were buried beneath the ground, and followed its contours; obstructing peaks were circumvented or, less often, tunnelled through.
