History
As a series of islands surrounded by a salt-water lagoon, Venice lacks natural sources of freshwater. As a result, Venice has found alternative ways to obtain freshwater for the city. As far back as the 6th century, Venetians built well systems to collect and filter rain to be stored as freshwater.
Venetians depended on this system for their fresh water supply until 1884, when a modern water supply system was established [2]
Function
The general design of a well and cistern typically includes a clay basin that stores rainwater. This water collects through street-level drains, filters through fine river sand, and then accumulates in the basin. There is a brick or stonewall well shaft that allows access to the water from the street level. These wells served as sources of fresh water in Venice. The water is retrieved from a structure called a wellhead.
