We want to be connected, quickly, on ever-smaller devices. They wanted to dominate, not share or learn from others. How could the Romans make this happen on such a large scale? Why did the Romans want to devote their resources to large monuments? In today's technology, engineers design for The Small. Superior military installations and camps frightened the opponent. The Romans were saying: "Look at us: we have all the resources and we will be here forever." About 1000 cities were created or transformed by the Romans. The city center of even the most modest showcased the civic buildings that Rome prized: temples, the forum, theater, library, baths and other waterworks, sometimes an amphitheater, basilicas, and the agora (market.) Note what the Romans did not build: schools, hospitals, or public housing.At this tower, the turning angle is about 55 degrees.Additional technical details below: The longest of the eleven aqueducts for Rome, the Marcia, covered 56 miles (91.4 km).Though the Romans did not calculate flows, we know the "carrying capacity" of ten of the aqueducts for the City of Rome was around 300 gallons of water per Roman per day.In comparison, San Francisco, CA, which today is similar in size, terrain, climate, and source of water, uses only 83 gallons per resident per day (2009). Roman technology was all about power, displayed very publicly.
One, the Aqua Marcia, continued to supply Rome with water well into the Middle Ages. If invaders cut off the water supply, the Romans repaired them when the invaders moved on.The aqueducts declined mostly from lack of demand as cities de-populated and shrunk.In the hinterlands, a lack of engineering skills among the few who remained in a city made it too difficult to maintain them. At the end of a Roman aqueduct, castella received and stored the water.A consistent, gentle slope was the goal of the Roman engineers.The slope of the Pont du Gard aqueduct in Southern France drops only 2 feet per mile along its length of 31 miles.
