Blonde Girl Reveals In The Backyard Garden At The Fountain

How Fountains Work
From Roman times until the 20th century, fountains operated by gravity, requiring a source of water higher than the fountain itself to make the water flow. The greater the difference between the elevation of the source of water and the fountain, the higher the water would go upwards from the fountain.
In Roman cities, water for fountains came from lakes and rivers and springs in the hills, brought into city in acqueducts and then distributed to fountains through a system of lead pipes.
