How Does Trevi Fountain Work

Water supply

Trevi Fountain is one of the most famous fountains in the world. It is located in Rome, Italy and its water is supplied from a natural source. The fountain’s water source is the Aqua Virgo, an ancient aqueduct built in 19 BC. The aqueduct follows the route of the Virgin aqueduct, which was built following the path of a Roman aqueduct by Pope Nicholas V. The Aqua Virgo or the Aqua Vergine, as it is commonly known, originates from the Salone Springs, located in the laziness hills 20 km south of Rome. From there, it is redirected to the city through many underground tunnels, tunneled above ground. From the fountain’s main tank, water is distributed to other tanks located in the city of Rome such as the Piazza Navona, the Bocca della Verità and the Monumento ai Caduti.


Trevi Fountain is a masterpiece of Roman architecture that has been a source of inspiration for many artists throughout the centuries. Built in the early 18th century, the fountain was designed by Italian architect Nicola Salvi, and was later completed by Pietro Bracci. The fountain is the largest Baroque fountain in Rome, measuring 85 feet in height and 55 feet in width. It is composed of several sculptures, depicting different scenes from mythology and Biblical stories. The most iconic figure is Neptune, the Roman god of the sea, which stands as the central figure of the fountain. Other statues and figures include Oceanus and Abundance, two river gods that are located at the two sides of Neptune, as well as two ancient goddesses: Salustia and Triton.

Mechanical underpinnings

Trevi Fountain is not only visually stunning, but mechanically impressive as well. Despite its age, the fountain is still able to bring to life a beautiful display of water, thanks to its complex pumping system. The fountain is driven by an underground mechanical system, composed of a series of pumps, tanks and a network of pipes that allow water to flow through different levels of the fountain basins. This system is powered by electric and pneumatic motors, which pull the water from the Aqua Vergine aqueduct and distribute it to the various tanks and basins of the fountain. In addition, the fountain also has a reservoir, which stores excess water, and a water filter system that cleans water as it passes through the pipes.


Trevi Fountain, in addition to its impressive water display, is also illuminated with an impressive lighting system at night. The fountain is lit up with a set of 288 lights that are positioned in such a way, as to highlight the different sculptures and figures of the fountain. In this way, the fountain’s beauty is highlighted during night time and gives the illusion of motion in the water. The lights can be adjusted for different occasions and events that take place in the town.


The fountain is regularly maintained by a team of engineers and technicians who are in charge of maintaining the complex mechanical and electrical systems of the fountain. This includes regular cleaning of the fountain, as well as maintenance of the pumps, motors and pipes. The fountain is also inspected annually, to ensure that it is safe and properly functioning.

Public access

The fountain is open to the public, and visitors can enjoy its majestic beauty anytime throughout the day. However, it is important to note that the fountain is also a popular spot for tourists and many visitors throw coins into the fountain as a symbol of good luck. In recent years, this practice has become very popular, and to help protect the fountain, the city of Rome has installed cameras that monitor visitors and prevent them from damaging the fountain.

In addition, the fountain is connected to a wastewater treatment plant and all wastewater is treated before it is released into the environment.
