Trevi Fountain controls its artful waterplay with precise engineering

In Italy, the Trevi Fountain stands as a monumental representation of baroque artistry, drawing millions of tourists each year who marvel at its intricate sculptures and cascading waters. This iconic fountain not only captivates admirers but also relies on a hidden water management system critical for its operation. The water supply originates from the Aqua Virgo, an ancient Roman aqueduct positioned 16 kilometers away. To ensure consistency in the water flow, two electric pumps recycle a total of 126 liters of water per second, rigorously monitored by ACEA, Rome's water management authority. The careful regulation of this water is vital; even minute variations can affect the beautiful water displays and thus the structural integrity of the fountain itself. Lurking behind the ornate facade are maneuvering chambers housing both modern and historical equipment that have been in play since the 18th century, including a hydrometer that measures water levels. This chamber serves as a stark contrast to the lively atmosphere of tourists who come to toss coins, a traditional gesture thought to guarantee their return to Rome. Visitors are generally oblivious to the behind-the-scenes workings that ensure the fountain's mesmerising performance, illustrating the blend of old and new technologies. In this way, the Trevi Fountain not only serves as a cultural icon celebrating Rome's rich history but also exemplifies the engineering feats that continue to sustain its legacy.
