water tower

water reservoir that supplies water to an entire area

A water tower or elevated water tank is a very large tank constructed for the purpose of holding a supply of water at a height sufficient to pressurize a water supply system. Many water towers were constructed during the industrial revolution and some of these are now considered architectural landmarks and monuments and may not be demolished. Some are converted to apartments or exclusive penthouses.
