The Pont du Gard: The Finest Example of a Roman Aqueduct The measurement of allowances was basically flawed; officially approved lead pipes carried inscriptions with information on the pipe's manufacturer, its fitter, and probably on its subscriber and their entitlement; but water allowance was measured in quinaria (cross-sectional area of the pipe) at the point of supply and no formula or physical device was employed to account for variations in velocity, rate of flow or actual usage. Water from aqueducts was also used to supply villas, ornamental urban and suburban gardens, market gardens, farms, and agricultural estates, the latter being the core of Rome's economy and wealth.[5].
