Roman aqueduct
Rome's first aqueduct was built in 312 BC, and supplied a water fountain at the city's cattle market. By the 3rd century AD, the city had eleven aqueducts, sustaining a population of over a million in a water-extravagant economy; most of the water supplied the city's many public baths. Cities and towns throughout the Roman Empire emulated this model, and funded aqueducts as objects of public interest and civic pride, "an expensive yet necessary luxury to which all could, and did, aspire".
Acueducto de Ponce
The Acueducto de Ponce (Ponce Aqueduct), formally Acueducto Alfonso XII, is the name of a historic gravity-based water supply system in the city of Ponce, Puerto Rico. It was designed in 1875 by Timoteo Luberza and built the following years. This aqueduct was the first modern water distribution system built in Puerto Rico.
