Old Piedras River Aqueduct

This aqueduct dates to the mid 19th century and it was important for the urban development of Río Piedras.

The waterworks were critical for their supply of clean water which was fundamental to the city's growth along a main corridor that still exists as Ponce de León Avenue.

The waterworks went through many upgrades since then done by American British engineers that were completed by the time of the Spanish-American War of 1898, with some main components installed some years later, between 1917 and 1918.
