The Aqueduct: Beginning of Nowadays Water Supply
Once collected in the distribution tank, the water was carried out to various places through lead or tile pipes (fistulae), that were connected to the castellum by a "delivery nozzle" (calix). An interesting phenomenon, regarding the distribution tank, is the law governing the hierarchy of delivery. Vitruvius' treatise on architecture explains the chain of delivery
The "public sector" philosophy regarding distribution patterns was indeed socialistic. The aqueduct's primary purpose, in theory, was to provide the masses with bountiful supplies of water. Naturally their was a water tax, and this was determined by the size of the calix that was connected to the distribution tank. Furthermore, a premium was instituted for all private deliveries.
What will become increasingly more apparent are the scope and scale of the benefits that the aqueduct yields. For example, other than pure monetary gain, the aqueduct allowed for the implementation of impressive monuments, buildings and fountains. These examples allude to the propagandistic nature of the aqueduct; for an emperor could not only rally around his contribution of an augmented water supply, but also utilize that water to fuel recreational areas for the public.
